cans of Treading Lightly, Thorn's Keto IPA

Treading Lightly: Low-Carb & Keto-Friendly IPA

The words “low-carb” and “IPA” are not often seen together. In fact, when asked, most people can only come up with one low-carb beer in general and that’s Michelob Ultra. Recently, the Keto diet has been gaining popularity as many people have found success in losing weight by following its low-carb ways. Unfortunately for many keto beer lovers, they have either had to give up drinking beer or carefully budget one beer in that might take up their carbs for the whole day.

Luckily, our brewers have been working on something special for all of the carb-conscious beer drinkers out there. Treading Lightly is an IPA that’s both full of flavor and light on carbs. The secret is using amyloglucosidase enzymes which can be used to degrade starch polymers and maltose to glucose in the beer creating a low carb beer with a decent ABV still. This IPA is bright, crisp and very dry. The Citra and Amarillo hops burst through your palette creating a beautiful session IPA that rings in at about 104 calories for a 12 oz can and just 2.9 carbs while still maintaining a 4.3% ABV. As an added bonus, the beer is Gluten-Reduced making it easier for those who are sensitive to gluten.

Thorn brewmaster, Eric O’Connor, had a lot to say about Keto, low-carb diets and his philosophy on brewing a beer that everyone on any diet can enjoy:

“The concept of the keto diet is not necessarily new. Basically, similar forms of the diet such as Atkins, South Beach and more recently, Paleo, were all slightly different forms of Keto. Keto, short for Ketosis, basically centers on the science that in the absence of enough carbohydrates, your body uses fat for fuel. This is very useful for weight-loss since the most efficient way your body gets energy is to burn sugars. If you eat them directly, however, you will store the rest as fat, which can be difficult to burn off if your body has access to sugars. 

Your body keeps a sugar reserve in your liver in the form of glycogen and in the absence of dietary sugar, it will burn that until it is consumed, at which point it will start burning your fat for energy. It takes little ‘effort’ for your body to switch back and forth between dietary fat and burning body fat, whereas there is a lag between consuming sugar and then switching to fat. It usually takes the average person 3-4 days of eating under 50 grams of carbs per 24 hour period and then under 50 grams per day afterword to remain in ketosis. 

Atkins and Paleo diets are different in that they may replace carbs with proteins but are not necessarily high-fat diets. While alcohol technically takes you out of Ketosis, it does only long enough to burn the alcohol, then your body immediately starts burning fat again.

It should be noted that Keto is not healthy for everyone all the time, and it’s always wise to consult one’s doctor.  We also do not claim that a light, lower carb beer is a healthy diet food. But if you do want a real tasting IPA that will likely keep you burning fat if you limit other carb sources that day, our new beer could be for you.  It’s also just a damn tasty beer for those not on a diet but looking for a lower ABV option that’s not a lager.”

Treading Lightly IPA is available now in all three Thorn tasting rooms on draft and will soon be available in cans along with our other core beers. Now you don’t have to give up something you love to also achieve your weight-loss goals…Treading Lightly is here for you.

The Murky History of the IPA

With the triple IPA season upon us, we thought it would be a good time to revisit the origin story of the mighty IPA. What’s interesting is that the story of how IPAs got their start is somewhat hazy. The most well-known storyline appears to swing from muddled to exaggerated to outright wrong but it’s so well known it’s hard to sift through information and find out what is fact and what is a myth.

When Conventional Wisdom is Wrong

If you ask most people how the India Pale Ale style was invented, you will get something along these lines:

In the early 1800s, the East India Company was shipping supplies to British forces overseas, in India, on their way to fill their ships with spices, silks and other valuables from the Far East.  The popular beers to drink at the time in Britain were stouts and porters, both of which were subpar beers to ship across the violent seas, and they often ended up stale, spoiled or infected. Also, the heavy beer wasn’t what was craved in the hot Indian climate, so even if it did arrive unspoiled, it was met with a middling reaction. George Hodgson’s Bow brewery decided that instead of sending a porter, they would try to send what was called an “October Beer.” This strong, pale beer was brewed at harvest time and loaded with just-picked hops to keep a fresh taste even when it was aged, sometimes for years. Apparently, the rough ocean journey matured this beer much like it would taste after 2 years aged, so when it arrived, it was at peak flavor. The resulting brew was a hoppy success and created a taste for India Pale Ale in India as well as back in Britain.

This paragraph came from one of our blogs about IPAs from a couple of years ago and features claims that come from sources like Business Insider and The Guardian. According to Zythophile and other sources, however, there are some myths in this version of the IPA origin story.

The first issue is that there appears to be no evidence that Hodgson’s brewery invented IPAs or that IPAs were “invented” at all. It’s more likely that this style of beer developed over time starting in 1709 when pale ales first began being sold in London. Over the years, these beers became known as “Pale ale prepared for the India Market” because of their popularity over there and then shortened to India Pale Ale. Hodgson was definitely the most well-known exporter of pale ale to India in the early 1800s but the pale ale that Hodgson was shipping to India wasn’t termed India Pale Ale until 40 years after he started exporting the beer.

The second myth in this storyline is that the ale being shipped to India was not primarily consumed by British forces. The troops preferred a homey porter to other styles of beer and it was readily available in India. In fact, porters and stout shipped just fine and were no more likely to spoil than pale ales. The pale ales exported to India were most often consumed by the upper and middle-class European expats who lived in India. They also found their way to military officers and civilians who were working for the East India Company at the time.

The third and perhaps the biggest myth is that strong IPAs were shipped over other styles because they were better preserved over the long journey. Not only did beer not need to be “strong” for the seaward journey, but IPAs were not really strong at the time anyway, usually around 6%. Sure many beers arrived spoiled or infected but that had nothing to do with the style of the beer and mostly had to do with the packaging and how the barrels were treated on the ship. While it is true that many breweries added extra hops to the beers being sent to warmer climates, this was commonplace by the 1760s.

In the early 1900s, IPAs fell into the British beer background; brewed occasionally but not really focused on. Then in the 1970s, IPAs were brought back with gusto by American craft brewers. They took the English IPA and amped up the hops, the alcohol content and reduced the amount of malts, creating a bold, hop-forward beer that is best consumed fresh.

Go West (Coast IPAs)

Brewers here on the West Coast have tapped into an even more amped up version of the American IPA, with even higher alcohol levels, more intense hoppy aromas and serious bitterness that is loved by many but also can be too extreme for some palates. West Coast IPAs are sometimes accused of lacking subtle flavors after the bracing hoppiness that slaps your palate with the first sip but this slap is exactly what many beer-drinkers love, and one of the reasons that IPAs are still one of the fastest growing segments of the craft beer market.

While some beer connoisseurs lament the rise of the IPA and its palate blowing characteristics, IPAs aren’t going anywhere anytime soon. They are still far and away the most popular style of craft beer and their sales continue to grow with IPA sales rising by 10.1% in the US over the last 12 months. Now, with the additional style of hazy IPA becoming mainstream we have more hoppy beers than ever to kick our palates into submission.

A Most Brut-iful Beer

One of the most exciting aspects of craft beer is the sheer creativity displayed by brewers all over the United States. The sky is the limit and while not all experiments get the desired results or reactions from beer drinkers, each creative brew brings about opportunities for new ideas and ultimately new beer. Over the last few years, we have seen Hazy IPAs rise in popularity and production. Now, the newest kid on the block is the Brut IPA, an IPA that is bone dry, pale in color and ebulliently effervescent. Created at San Francisco’s Social Kitchen & Brewery by brewer Kim Sturdavant, this beer has caught the fancy of craft brewers all over the country who are trying their hand at this brand new style.

What Makes It A Brut?

Brut IPAs came about by experimenting with enzymes. Amyloglucosidase is an enzyme commonly used to break down the sugars from malts to cut down residual sweetness by reducing sugar levels. Most often used when brewing Imperial stouts to make them more drinkable, Sturdavant began using it in his triple IPA to cut down on the malty sweetness that can be a second-hand effect of such a high ABV beer. He decided to try using the enzyme in a regular IPA and the result was the birth of a brand new style IPA.

While this style hasn’t even been in existence for a year yet, brewers are excited to get in on the Brut IPA action. Brut IPAs are so dry and light that they are the perfect antidote to the dank, juicy hazy IPAs that are everywhere, right now. This style allows the hops in the beer to be highlighted in a brand new way by pulling out different flavors from the hops. At this point, many of the hops used in Brut IPAs are the more tropical varieties found in hops like Cascade, Citra, and Centennial which are all considered New World Hops.

Staying Power

While no one can predict if the Brut IPA style is here to stay, the fact that it’s an IPA is a good start. IPAs are still far and away the most popular beer style in terms of craft beer sales. While many industry insiders have expressed hop-fatigue, the fact of the matter is that the average craft beer drinker still goes for an IPA more often than any other beer style. In fact, right now there are 849 brut IPAs rated on Untappd. Not too bad for a style that has only been in existence since November of 2017. If anything, coming up with unique names for this style of beer seems to be somewhat of a challenge considering on Untapped there are no fewer than 46 brut IPAs named “I am Brut.”

thorn beer brut ipa

Here at Thorn Brewing, we wanted to get in on the brut IPA action and brewed up a batch with our friends over at Pure Project. Houblon Grand Cru Brut IPA comes in at 7.4% ABV and is delightfully bright and effervescent. We caught up with Doug Pominville, Barrio’s head brewer, in the brewhouse recently and asked him about this collab:

“When a new style emerges in the craft beer world and catches some legs it’s always fun to give a go at it while its still evolving into its own. When Winslow hit me up to brew a collab at a Thorn it was an immediate, yes, then he mentioned a brut IPA and it was a no-brainer that we needed to get this on the brew schedule. While most breweries have been using rice to lighten the body and color while still adding fermentable sugars, we decided to use wheat instead. The wheat adds some mouthfeel to a beer with minimal body while helping to produce that straw yellow color you expect from champagne.  The hops we chose were selected to help bring out the flavors of an outstanding champagne; Pear, apple, white grape, grapefruit, & peach. The beauty of this beer style is that it’s low in calories and carbs. The enzymes we add break down the maltose and starch polymers into glucose so they can be fermented out by the yeast. This leaves a very dry beer with little to no residual sugar and starches. Making this beer perfect for the hop head who is trying to cut back on the LBs while still enjoying a tasty brew.”

We are releasing Houblon Grand Cru on Friday, August 31st at our Barrio Logan location in 750 ml cork and cage bottles and they will be available until we sell out!

thorn brewing barrel aged beers

Barrel-Aged Beers

Barrel-aged beers are all over the craft beer scene and with good reason. Delicious, deep, and dark, just like your secrets, barrel-aged beers are a lovely addition to any brewery’s portfolio. They definitely aren’t for everyone, however. Someone looking for a light, refreshing, hoppy beverage isn’t going to find those characteristics in a barrel-aged beer, but they will find a sultry, rich, taste-explosion that is created by the use of wood barrels and their influence on the beer housed in them.

While aging beer in barrels is nothing new to the beer scene, using bourbon barrels is something that has jumped to the forefront since the mid-90’s. By most accounts, the first brewery in the U.S. to use bourbon barrels to age their beers was Goose Island. Now, if you are a follower of this blog, you know that Goose Island is owned by AB InBev, and in fact was one of the first craft breweries bought by big beer back in 2011. But one thing is for sure, their Bourbon County brand not only paved the way for hundreds of other breweries to follow the bourbon-barrel train but is also still killing it in this niche market.

Why Bourbon Barrels?

Barrel-aging has always imparted flavors into beer but bourbon barrels are something special. First, wood gives off chemical compounds that will be absorbed into the beer. Lactones, organic compounds in the ester group help impart a floral aroma and flavor. Phenolic aldehydes give off vanilla and the simple sugars in the wood help bring out caramel notes from the beer. In the start of its barrel-journey, the beers will absorb strong vanilla and caramel flavors as well as the leftover flavorings of the bourbon that used to live in that barrel. The cool thing is that over time, the beer becomes one with the barrel, in a way. It soaks deep into the staves before being pushed back out which helps it to absorb not only the rich flavors of the previous spirit but also the wood itself. That’s one of the fun things about bourbon barrels. It’s a bit like wild yeast, you don’t know exactly what you are going to get from the cocktail of compounds in the barrel.

Barrel-Aging Factors

There are a few major factors that are at play when one thinks about barrel aging a beer.

Type of Beer

While brewing is all about experimentation and probably all styles of beer have been aged at one time or another with varying degrees of success, beer best suited for barrel aging is strong, dark and of high alcohol content. Any beer that counts on “freshness” as a flavor (sorry IPAs) wouldn’t be a good fit. But this does make Imperial stouts and Belgian strong ales great candidates. For Thorn’s first barrel-aged bottles we used an Imperial Russian Stout and a Belgian quad ale. Both of these beers can stand up to the flavors that are imparted by the bourbon-barrel and they only get better as they get older as freshness is not really a huge factor in either of these beers when aged appropriately.

The Barrel

While most any barrel can be used to age beers some are better than others. This time around we are using bourbon barrels from Four Roses but previously we have aged beers in red wine barrels that made delightful sours like our Carneros Crush Sour. While bourbon barrels are the most popular to use because the flavors of bourbon already play well with the flavors of most dark beers, there is a rise in popularity of using tequila barrels to age beer too. Most barrels used to age liquor and then beer are made of white oak. Oak is an incredibly strong wood and also imparts flavors that work with liquor and beer.


How long beer is barrel-aged for is really dependent on what the brewer is trying to achieve, flavor-wise. Beer can be aged for as little as 1-2 months if wood and bourbon notes are the goal while aging for 6-12 months will bring out the deeper floral and vanilla notes from the barrel. The more time in the barrel the more time the beer gets to soak into the staves of the barrel and during temperature changes, this becomes really important.


Temperature is a crucial factor in barrel-aged beers. While conventional barrel-aging wisdom says that it’s ideal to keep barrels at a constant temperature between 55-60 degrees, that’s not necessarily the case for many barrel-aging programs. Variations in temperature will make the wood contract and expand which helps in the staves absorb and extract the beer throughout the aging process, lending all the delicious flavors that we know and love. In fact, many breweries, including Thorn don’t use any temperature controls in their barrel warehouse precisely to get the substantial temperature swings provided by the natural climate.

Thorn Barrel-Aged Beer

We are releasing our first bottled, barrel-aged beers on July 29th and are throwing a party to celebrate! Not only can you come and pick up a bottle of both the barrel-aged Dark Tsar Imperial Stout and the barrel-aged Abbey Roof Abbey-style ale, but you will be able to taste these two beers as well as three other barrel-aged beers that we have had cooking in the back over the last year. There are only a few tickets left for our VIP experience where you get two bottles, a glass, a guided tasting through all five of our barrel-aged beers, BBQ lunch, brew tour and $5 beers the rest of the day (which is a smoking deal for barrel aged beers). Or just stop by and taste through the beers, listen to live music, enjoy food from the Meat Locker BBQ and grab a couple of bottles to go. For more info on the event head to Eventbrite or the Facebook event page.

Haze Craze: Hopster Pot, the Juiciest Beer in San Diego?

Chase away June Gloom with some haze of your own; Thorn’s Hopster Pot Hazy IPA. Now, you can get this delicious beer in six-packs all over San Diego and L.A.! We are so excited for this can release because not only is Hopster Pot the juiciest beer around, but it also brings many of the Thorn team back to their roots.

Let’s Get Hazy

Let’s be clear about this cloudy trend: Hazy IPAs are here to stay. While some may have thought this style was a flash-in-the-pan, it is showing some serious hop-legs. Not only did GABF add a hazy beer category this year, but the BJCP just released style guidelines for New England Style IPAs. Their comments on this type of beer:

“An American IPA with intense fruit flavors and aromas, a soft body, and smooth mouthfeel, and often opaque with substantial haze. Less perceived bitterness than traditional IPAs but always massively hop forward. This emphasis on late hopping, especially dry hopping, with hops with tropical fruit qualities lends the specific ‘juicy’ character for which this style is known.”

The “substantial haze” is created through a few different brewing steps. First, the beer is aggressively dry-hopped. Dry-hopping is when hops are added to the tank after fermentation but before packaging. Adding hops at this stage doesn’t add bitterness, but it does add delicate hop aromas and tastes that can otherwise be lost in the boil. While the addition of tons of hops at the end helps with the haziness, this isn’t the only factor. It also can depend on the use of high protein grains like flaked oats and wheat as well as the type of yeast used. Many of the hazy IPAs from New England use Vermont Ale yeast while many San Diego breweries, including Thorn, use London 3 yeast for their hazy beers giving West Coast hazy IPAs a slightly different profile. Hazy beers also have higher fruity esters and lower flocculation than many clear IPA counterparts. Additionally, even the make-up of water has an impact on this type of beer. When you put all this together, the old saying, “hazy = lazy” just doesn’t make sense. When done correctly, hazy beers are harder to brew than clear IPAs making hazy the opposite of lazy.

Hopster Pot Love

We have been getting a lot of love for our newest addition to the Thorn can line-up, Hopster Pot Hazy IPA (7% ABV). This hazy wonder is hopped with Amarillo, Citra and Ekunnot hops but each new batch will use a different blend of hops. To find out what hops are in your Hopster Pot, check out our Hazy Beer Page on our website.  We like to think of our hazy IPA as more of a West Coast Hazy IPA than the full-on New England Style IPA. It’s slightly drier and slightly more bitter, with brighter hops than many of the East Coast IPAs. Hopster Pot is like a hazy-hybrid, bringing together the style, methods of a New England style IPA with some West Coast twists.

This beer is really a labor of love for the whole Thorn team. While our three original owners/brewers are all San Diego natives, we also have a lot of East Coast transplants. Doug Pominville, our hazy head brewer, is from New Hampshire, cellarman, Kenny Maguire, is from Connecticut, sales-guru, Tom Kiely is from Massachusetts, Dave, our warehouse manager is from NY and I’m from Vermont, myself, so there is a full chain of New Englanders taking this beer from tank-to-shelf and everything in between!

Now that Hopster Pot is available throughout San Diego, Orange County, and Los Angeles, it’s even easier to get your hands on some of this juicy wonder. For info on where to get our beer check out our interactive map here…

For the Love of Cans

The Brewer’s Association just released a report outlining Craft Beer Packaging Trends in 2017 and what was found is that people are loving beer in cans! Cans saw a nice jump in growth the last year for two main reasons. Not only are breweries switching from bottles to cans but also, breweries that have a higher can share are growing at a faster rate than breweries that have a lower share of cans. This can be attributed to the size of companies where smaller breweries tend to be able to grow faster than larger breweries.

But why the shift? There are a few different reasons why many breweries choose cans over bottles.


Light is one factor that can stand in the way of optimal beer flavor and is responsible for the dreaded, “skunked” beer. This off-putting flavoring is due to the light-sensitivity of the hops in the beer. In fact, the term “skunked” is scientific in its basis. Chemists from the University of North Carolina Chapel Hill studied what makes a beer skunky and found that when they hit three isohumulones (the compounds responsible for the light sensitivity in hops) with enough light, it created a compound called “skunky thiol” which has the same chemical make-up as a skunk’s noxious spray. While brown bottles help the issue somewhat, cans and kegs are really the best way to make sure that light doesn’t change the flavor of a beer.


While oxygen is both a friend and an enemy to beer, the process of oxidation can be damaging when it’s introduced after early fermentation. Oxidation can cause that “stale beer” taste and is most often detrimental when it occurs during packaging. Before that, if oxidation occurs, it will be caught by the brewing team and not packaged at all. Air doesn’t act alone when it comes to oxidizing beers, however. Temperature also plays a major role in oxidation and the resulting stale beer. Cans are better than bottles at keeping oxygen out because of how they are filled in the canning line. Also, there are issues with oxygen exchange through bottle caps that can tamper with the flavors.


Using cans to package beer is better for the environment for a couple of different reasons. First, because cans are lighter in weight and often can fit more cans in a specific space (like the back of a delivery truck) vs. bottles, they leave less of a carbon footprint. More beer on a truck means fewer trips for that truck and a lighter weight mean less gas is used for those deliveries. Second, cans are made from a higher content of recycled material than bottles (cans are 70% recycled materials) and people recycle cans 20% more often than they do glass.

Cans are a win/win for the brewery and the consumer so the next time you are faced with the choice of what beer to buy at the store, make it beer in a can!


Clarity Ferm to the Rescue

2017 was a good year for gluten-sensitive beer drinkers. After growing 136% between 2013 and 2015, the gluten-free food and beverage category continued to see strong growth throughout this past year. While people who suffer from Celiac Disease have long omitted gluten from their daily lives, there are more and more people who have chosen to cut it out for diet or health reasons. Luckily, thanks to a little product called Clarity Ferm and the growing use of it by local breweries along with gluten testing, many are now able to add craft beer back into their diets.

Clarity Ferm Fun

Clarity Ferm is an enzyme that breaks down proteins and has historically most often been used in the brewing process to reduce chill haze. Chill haze is different than the haze we see in all of the New England style/hazy IPAs. It happens when proteins from the malt form a bond with the hop polyphenols, which are seen as suspended particles in the beer and create a yeasty, hazy color in cold beers. To get away from this, brewers have long used Clarity Ferm to reduce the chill haze as well as increase shelf stability of their beers. With the rise of the gluten-free movement, this enzyme is now also sold as a solution for lowering gluten levels in beers to incredibly small parts per million. In fact, using Clarity Ferm can reduce the beer’s gluten to well below the international standard of 20 ppm for calling the beer gluten-free. The U.S. has a higher standard for use of the term “gluten-free” so here in the states, these beers are considered gluten-reduced rather than gluten-free.

For many people who are gluten-intolerant and even some people with Celiac, this realization that many of their once beloved craft beers are actually ok for them to drink has been a huge boon. Furthermore, Clarity Ferm shouldn’t affect the taste of the beer so while a beer may be labeled “gluten-reduced,” it is not going to taste differently from that same beer were it not to use the Clarity Ferm and in some cases, blind tasters thought that the beer using Clarity Ferm tasted better than the original.

Gluten-reduced vs. Gluten-free

In the U.S., any beer that uses ingredients containing gluten, even if the gluten is reduced to the international standards of gluten-free, can’t be called gluten-free. The only beers that can be called gluten-free are beers brewed with alternative ingredients like sorghum and rice.

So how do you know which beers you may be able to try if you are on the wrong side of gluten? While a lot of your favorite breweries are using Clarity Ferm, if they aren’t testing the gluten levels then it’s probably not a good idea to wade into the gluten-waters unless you contact them directly or go to the tasting room and talk to the beer-tenders/brewers to find out for yourself if the beer you would like to drink is tested.

This was a recent topic of conversation on a craft beer industry Facebook group and there were some exciting additions to the list of breweries who use Clarity Ferm and also test for levels of gluten. Here is an unofficial (and incomplete) list of San Diego breweries that use Clarity Ferm in some or all of their beers:

  1. White Labs (all + tested)
  2. Stone Brewing (Delicious IPA)
  3. Alpine Beer Co. (all + tested)
  4. Second Chance Beer Co. 
  5. Duckfoot Brewing (all + tested)
  6. Mike Hess Brewing (all)
  7. Council Brewing (70% of beers)
  8. New English Brewing
  9. Booze Brothers
  10. Wavelength Brewery
  11. Culture Brewing 
  12. Abnormal Beer Co.
  13. Amplified Ale Works
  14. Burgeon Beer Co.

At Thorn, we often have a gluten-reduced option for people to enjoy. Please contact us at to inquire.

We would love to add more San Diego breweries to this list, so if you work in or know of a brewery that also uses Clarity Ferm in one or more of their beers and tests for gluten levels, please comment or email us at and we will update the list accordingly.

Also, please do your own research before trying these beers if you are gluten-sensitive. Most info can be found on the linked brewery websites, but if not, just give them a call and ask. Brewers are some of the most helpful and science-minded people around and many want their beer to be consumable by everyone, even those who have sworn off gluten.

Hello, I Love You, IPA

Whether you love ’em or hate ’em, IPAs are a formative beer in the craft beer universe. Still far and away the most popular craft beer style, IPAs are known and loved for their ability to wake up the taste buds with a kick to the face of hops and bitterness. Yes, it’s an incredibly delicious kick to the face, but it’s the reason why many people love, and other hate, the mighty IPA.

IPAs are King

First, let’s get into the fact that Americans love IPA. In fact, they love IPA so much that the dollar shares of IPAs are nearly double that of the next most popular beer style on the list, Seasonal Ale. What’s interesting about this graphic from the Brewers Association is that Pale Ale is so far behind IPA on this list. It’s been a conversation in our brewery as well as many others as to what defines a Pale Ale vs. a Session IPA with different opinions coming from different brewers. In the end, it seems to be a naming choice that the individual brewer makes. While Pale Ales generally have a slightly maltier backbone than many session IPAs, this difference tends to disappear more when you get into the category of West Coast Pale Ales, which to many can seem like lower-alcohol but just-as-hoppy IPAs. This graphic highlights the reason why so many brewers decide to call their lighter IPAs “Session IPAs” because when it comes down to it, IPAs just sell better than Pale Ales.

What’s With the Origin Story?

We’ve all heard the rumors: IPAs were invented by a brewer named George Hodgson, they were high in alcohol to survive the long journey across the seas and were made for British troops to enjoy while overseas. While none of this is far off, it isn’t exactly correct either. In the late 1700s, the East India Company was shipping supplies to British forces overseas, in India, on their way to fill their ships with spices, silks and other valuables from the Far East. Here is the first inaccuracy. Even though the beer was on a boat shipping supplies to British forces, the beer wasn’t really favored by the troops, who in fact still favored porters. The beer was consumed mostly by middle and upper-class British expats in India who had been consuming Pale Ales since the 17th century.  You also might have read that IPAs came about because stouts and porters of the time were sub par beers to ship across the violent seas and they often ended up stale, spoiled or infected. But all beers ran this risk at the time, including pale ales. While hops do act as a preservative, they were no match for the more primitive means of storage and shipping that beers faced during this time and arrived spoiled just as often as darker beers. In order to expand the market, George Hodgson’s Bow Brewery decided that instead of sending a porter, they would try to send what was called an “October Beer.” This strong, pale beer was brewed at harvest time and loaded with just-picked hops to keep a fresh taste even when it was aged, sometimes for years. Apparently, the rough, ocean journey matured this beer much like it would taste after 2 years aged, so when it arrived, it was at peak flavor. The resulting brew was a hoppy success and popularized the taste for Pale Ale in India as well as back in Britain, though this style of beer wasn’t called IPA until 1835.

Double IPA = Imperial IPA

Being that Americans do everything bigger, it was only a matter of time before we started producing a super-sized IPA. While Imperial Ales, in general, have been around since the 1700s, the term “Double IPA” is quite new. It was first coined in 1994 by Blind Pig brewer, Vinnie Cilurzo, who was playing around with his IPA recipe and the amount of hops that were usually used in such recipes. What came out of this was a hop-bomb that excited the palates of Southern Cali craft brewers at the time and then exploded nationally.

So what’s the difference between Imperial IPAs and Double IPAs? The answer is nothing, really. Imperial, double and even triple IPAs are labels to connote more hops, more malts, and more alcohol but there is really no standard for when a brewer has to use the term or which term to use. The terms are pretty interchangeable, though double/triple is most often used in terms of IPAs here in the states. Another thing to think about is that the U.S. craft beer movement is heavily influenced by Belgian beer where there are dubbels, trippels, and quads. They also refer to the beer being a bigger version itself, with more hops, malts, and increased ABV. Their origins, like most beer history, are also somewhat murky but one theory is that it has to do with Trappist Monks marking two, three and four X’s on a bottle of beer to denote how strong it was and what number it was in a series.

The Constant Evolution

One of the coolest things about the craft beer industry is that it seems to be in a constant state of creative development and experimentation. This idea is front and center with IPAs and the ever-evolving use of hops. While most people know the big proprietary hops including Amarillo, Citra, Mosiac, Simcoe, and Warrior, there are tons of other varieties of hops out there that brewers are brewing with which create exciting new flavor profiles in IPAs. All About Beer published a piece on “Hops to Watch in 2017” that included Idaho 7, Azacca, Cashmere, Jester, and Comet (described as Citra’s little sister) varieties. To push the creativity even further, many brewers have started using Lupulin power and hop oil in their brews which only adds to the complex flavoring that a beer can provide.

In the end, while IPAs aren’t for everyone, they certainly are loved by many, if not most, craft beer consumers. So raise a pint of your favorite IPA in honor of National IPA Day (Thurs, August 2nd) and savor the flavors that evolved over the last few hundred years to get us to the delicious state of beer we are in today.

It’s All About the Package

While it’s no surprise that consumers, in general, are influenced by product packaging, it was certainly surprising to learn just how much craft beer packaging influences what people choose to buy. Recently, Nielsen released data on craft beer packaging and the role it plays in who ultimately purchases the beer.

It’s All About the Packaging

First of all, we found out that 70% of craft beer buyers make their decision when they get to the store vs. ahead of time. With more than 3,905 new beers on the shelf in the last year alone, it makes sense that most people wait to decide what they are getting until they get to the store and see the selection.  So what steers people to buy a specific beer the most? A nice package.

In fact, 66% of people surveyed said that they were “very likely” to buy a beer based on its packaging and label. Furthermore, 71% say they more likely to try a brand that has bold and interesting packaging. But what do people like when it comes to a beer’s label? Different features such as brand name, logo, color scheme, bottle shape and color, and the box or carrier that hold the bottles were all evaluated. Interestingly enough, the box/carrier came out on top as having the most influence, at 48%. Where the beer is produced came in second at 43%. They also found that more consumers were drawn to illustrations and logos vs. what was actually written on the labels.

Brands On Top

For the study, Nielsen tested 17 different brands that are top sellers with a nearly equal split between East Coast and West Coast beers. The brand that fared the best was Kona Brewing, which came out in the top two designs in both East and West coast demographics. Deschutes and Saint Archer rounded out the top 4 spots, after Kona’s Big Wave Golden Ale and Castaway IPA. What’s interesting is that While Kona and Deschutes are similar in their graphic, illustrative style, Saint Archer is quite different from both of these other brands. Maybe its clean cut, more modern design might help it stand out from those more illustrated styles or maybe it even speaks to a different consumer.

Coming Soon…

With all of this info in mind, Thorn Brewing Co. is entering the craft-beer-can-fray. We are really excited to announce that in mid-July you will be able to get 6-packs of Thorn Brewing cans in stores and bottle shops throughout San Diego. We are starting with four of our core beers; Relay IPA, Rock the Pale Ale, Foreplay Belgian Blonde, and Barrio Baja-style Lager. Here’s a sneak peek at what they will look like…

Now, it will be even easier to take our beer on-the-go whether you are heading to the park, the beach, a friend’s BBQ or just home to enjoy a cold one. Soon the canning line will be up and running down at our Barrio Logan location and we will be able to can even more of your favorite Thorn beers.

To wrap it up, yes, labels are important when buying a beer, but don’t let that outshine what is actually in the can or bottle. We’ve said it before and we will say it again, the thing you should be the most concerned about on a bottle or can is the freshness date or bottled-on date. The beer’s freshness is likely going to be the biggest influence on how your beer tastes no matter what the style is, but this is especially true for IPAs. That’s why we will be putting freshness dates on all of our cans so that you can make sure you are getting a fresh Thorn beer no matter if it’s here at the brewery or out in stores. And for those people who don’t know just how delicious our beer is yet, hopefully, our packaging will entice them give us a try.
