Biotransformation has become a buzzword in the brewing community, with many brewers even performing dry hopping at certain specific times to hit what is considered to be the “biotransformation sweet spot.” Academic literature does not support these claims. With the aid of enzymes developed for the wine industry, two experimental IPA beers were brewed: one with an enzyme preparation aimed at hydrolyzing glycosides and the other with a β-lyase preparation aimed at releasing bound thiols. Triangle tests for each treatment were carried out by a panel of over 25 participants, composed of brewers and judges, and showed that both beers were significantly different from the control, yet preference was overwhelmingly toward the no-enzyme IPA control beer. Furthermore, the descriptive analysis carried out by the same panel showed a clear trend toward both enzyme beers being less tropical/fruity and more herbal and/or citrusy, the exact opposite of the purported benefit of biotransformation.Special Guests: Leandro Meiners and Mati Cavanna.Sponsored By:Fermentis: Gusmer: BSG: Proximity Malt: ABS: Hopsteiner: Links:MBAA TQ 2020: Using Exogenous Enzymes to Boost Biotransformation‎BIRRATECNIA on Apple PodcastsBIRRATECNIA | Podcast on SpotifyWBC Connect 2020Webinars on TapUpcoming Events - Master Brewers CalendarCOVID-19
