Brett beer

Brett beer is a modern craft beer style that first appeared in the United States. The style is brewed with the addition of wild Brett yeasts (Brettanomyces or British fungus)—hence the name—which are slightly unpredictable and create beers with a wild and funky character.

The final profile of these beers depends on the base style, and Brett yeast will only add the funky element. Color, aroma, and flavor vary in character and intensity among the examples. The beers are usually light-bodied with flavor and aroma ranging from fruity to earthy or barnyard-like.

Young styles will usually have less funk than older Brett beers. Unpleasant flavor and aroma should not be noticeable. Brett yeast should be balanced with other elements.
