White Labs WLP820 Oktoberfest/Marzen Lager Yeast produces a very malty bock-like style. It does not finish as dry as White Labs German Lager Yeast. This yeast is much slower in the first generation, so it is recommended that you use a lager starter in the first generation or schedule a longer lagering time. White Labs yeast is world-renowned for quality and innovation, certified kosher, GMO free, and subject to thorough quality analysis before being packaged. This yeast comes packaged in White Labs' PurePitch packaging using the revolutionary FlexCell process, which creates yeast that has never been transferred or exposed to the environment. The PurePitch packaging is a recyclable, flexible material that allows for increased breathability, reducing the chance of gas buildup and maintaining the optimal environment for yeast.
