Thiolized

"Thiolized" in beer refers to the specialized yeast strains designed to release thiol compounds. These compounds can create intense tropical fruit aromas like grapefruit, passion fruit, and guava in beer. Thiols are naturally present in hops and malt, but typically they don’t release these fruity scents and flavors. Thiolized yeast strains can help evoke a tropical, citrus character and enhance the overall flavor profile of the beer, especially in hoppy styles like hazy IPAs.
