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.
