Hailing from a small brewpup in Cologne, Germany, White Labs WLP029 German Ale/ Kolsch Yeast accentuates hop flavors and works great in Kolsch and Alt style beers. It is good for alt beers like blond and honey. The slight sulfur produced during fermentation will disappear with age and leave a super clean, lager-like ale. 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.
