AAB 039: New Research into Biotransformation

Biotransformation are flavor- and aroma-releasing reactions during brewery fermentation.  Lately, there has been much discussion of biotransformation in hoppy beers like IPAs where bound thiols are released when yeast interacts with them.  So hops provide not only bittering acids and flavorful oils, and yeast provides not only alcohol and esters, but the combination of yeast interacting with hop chemicals (and sometimes malt chemicals) produces new flavors.  New research into biotransformation is causing brewers to reexamine how they use hops, how they choose malts and how they ferment.This Episode is Sponsored by:Estrella GaliciaEstrella Galicia is an independent, family-owned brewery  in northwest Spain, founded in 1906.Estrella Galicia Cerveza Especial is a world class lager, brewed using the finest Spanish malts, locally  cultivated Galician hops and the best brewing practices, in a state-of-the-art facility in La Coruña .
