There’s a new beer in town. Pale gold, effervescent, and oh so dry. Brut IPA has marched straight onto the craft brewing scene and is demanding your attention. This surprising IPA incarnation is the brain child of master brewer Kim Sturdavant from Social Kitchen and Brewing in San Francisco. Sturdavant experimented with using a glucoamylase – an enzyme usually used when brewing light pilsner and lager beer styles – on a standard IPA. The result was a lighter, drier beer - the Hop Champagne Extra Brut IPA was born. Since its invention in late 2017, Brut IPA beers - Brut for the dryness reminiscent of fine champagne - have surged in popularity across the craft brewing world.
A highly attenuated, low sugar beer isn’t a new thing of course. In fact, light or “diet” beers have been around for over 50 years. In the 1960’s the world’s first light beer “Gablinger’s diet beer” was created for the Rheingold Brewery by Joseph Owades. Owades worked to produce a low-calorie beer for weight conscious customers. To reduce calories, he used enzymes to breakdown more of the residual starch found in beer. Basically, long, unfermentable dextrin chains were chopped into smaller units which could be easily fermented into alcohol and carbon dioxide. Diet beer was here. Gablinger’s diet beer itself wasn’t a success (possibly due to an unappealing marketing campaign featuring a sumo wrestler) however the seeds had been planted and other diet and light lager beers continue to sell today.
Now the Brut IPA has taken reduced dextrin beers from light to luxurious, from diet to delicious. This newcomer looks set to become a classic. Dry, hoppy, effervescent. It’s so easy to enjoy. There is only one question. Just how do you brew it?
The Brut IPA is drier and lower in calories than prototype IPAs with the same alcohol level. If you want to brew the ultimate Brut IPA, you’ll need to first select just the right yeast strain and choose the perfect mixture of grist with or without adjuncts. After that there are 3 important points to keep in mind.
An alternative way to produce a light beer is by adding the glucoamylase enzyme during fermentation. If you go down this path it’s important not to get these beers mixed with regular beers as this enzyme is still active. To avoid damaging normal non-dry beers, the enzyme will need to be inactivated using flash pasteurisation. Talk to us to understand which method of light beer brewing is right for you.
