Originally isolated from strong English stock beer in the 20th century, White Labs WLP645 Brettanomyces Claussenii provides a low intensity Brett character. There is more of a aroma contribution than a flavor contribution, with the aroma being fruity and pineapple-like. B. claussenii is closely related to B. anomalus. White Labs yeast is world-renowned for quality and innovation, certified kosher, GMO free, and subject to thorough quality analysis before being packaged.
