White Labs WLP515 Antwerp Ale Yeast is a clean, almost lager-like Belgian type ale yeast. It is good for Belgian type pale ales and amber ales, or with blends to combine with other Belgian type yeast strains. There is a biscuity ale-like aroma present, and hop flavors and bitterness are accentuated. Slight sulfur will be produced during fermentation, which can give the yeast a lager-like flavor profile. White Labs yeast is world-renowned for quality and innovation, certified kosher, GMO free, and subject to thorough quality analysis before being packaged.
