Brut IPA
The Brut IPA is the driest beer in the IPA family — a bone-dry, ultra-pale, highly carbonated style modeled on the crispness of brut champagne. Borrowing its name from the wine world's driest designation, it strips out nearly all residual sugar to leave hop aroma floating over a finish of almost nothing at all.
#Origins
The Brut IPA was created in late 2017 by brewer Kim Sturdavant at San Francisco's Social Kitchen & Brewery. It spread quickly as a 2018 trend before settling into a niche — a textbook entry in Modern IPA Diversification.
#The Enzyme That Defines It
The Brut IPA's signature dryness comes from amyloglucosidase, an enzyme added during fermentation. Ordinary brewing yeast cannot ferment complex dextrins; amyloglucosidase breaks those dextrins down into fully fermentable simple sugars, driving the beer to near-zero residual sugar and a final gravity that can dip below 1.000. See Fermentation and Recipe Formulation.
The same dextrin-cleaving effect underlies hop creep. A Brut IPA deliberately harnesses what brewers of other styles fight to avoid — over-attenuation and extra CO2.
#Sensory Profile
| Element | Character |
|---|---|
| Appearance | Very pale, often brilliantly clear, lively bubbles |
| Aroma | Delicate floral, white wine, light citrus and tropical |
| Bitterness | Low — the style avoids harshness |
| Mouthfeel | Effervescent, thin, spritzy — see The Science of Mouthfeel |
| Finish | Bone-dry, leaving almost no trace |
#Why It Faded
The Brut IPA's extreme dryness is also its weakness: with no malt sweetness and low bitterness, there is little to mask hop fade or any flaw. As hop aroma oxidizes the beer can taste hollow — see Hop Fade and Oxidation. It remains a respected but minor member of the Specialty and Experimental IPAs family.
