Brettanomyces bruxellensis

Brettanomyces bruxellensis is a type of yeast used in fermentation, especially in winemaking and brewing. It is known for producing distinctive flavors and aromas, often described as fruity, spicy, or sometimes smoky, which can add complexity to beverages. While it can spoil some wines if uncontrolled, in certain styles like specialized ales and lambics, it is intentionally cultivated to create unique flavor profiles. It thrives in environments where other yeasts may not, and its presence influences the character and aging of the final product.
