Brettanomyces (Brett)

Brettanomyces, commonly called Brett or Brett, is a type of yeast used in brewing and winemaking. Unlike typical yeast that makes drinks taste clean and fruity, Brett produces unique flavors and aromas, often described as earthy, barnyard, or funky. It’s valued in certain craft beers and sour wines for adding complexity and depth. While sometimes seen as a spoilage organism in other contexts, brewers intentionally cultivate Brett to create distinct, flavorful beverages. It thrives during fermentation, especially in aging processes, and its presence can influence texture and aroma significantly.
