Brew authentic malt-forward German lagers with White Labs WLP833 German Bock Lager Yeast | PurePitch® Next Generation, a premium liquid lager yeast prized for producing exceptionally clean fermentation while emphasizing rich malt complexity and a smooth, refined finish. Each 70 mL PurePitch® Next Generation pouch contains approximately 150 billion cells, providing enough healthy yeast to ferment a standard 5-gallon batch without requiring a starter for most moderate-gravity lagers. WLP833 is an excellent choice for brewing Bock, Doppelbock, Märzen, Helles, Baltic Porter, and other traditional German lager styles where clean fermentation and deep malt character are essential.
WLP833 produces a balanced fermentation profile that highlights caramel, toasted bread, and rich malt flavors while maintaining restrained ester production and excellent drinkability. Its medium flocculation promotes strong clarification during lagering, resulting in bright, clean beers with a rounded body and refined finish. The strain is especially valued for creating traditional Bavarian lagers with smooth character and layered malt complexity.
This liquid lager yeast features medium flocculation, 70–76% attenuation, STA1 negative status, and an alcohol tolerance of 5–10% ABV. It performs best between 48–55°F (9–13°C) and is packaged in White Labs' PurePitch® Next Generation pouch, which contains approximately 150 billion cells for reliable pitching rates and consistent fermentation performance. The strain is specifically selected for classic German lager brewing and excels in malt-driven recipes requiring clean, dependable fermentation.
For best results, store refrigerated between 33–38°F and do not freeze. Pitch cold into well-oxygenated wort and maintain fermentation temperatures between 48–55°F throughout primary fermentation. While one pouch is suitable for most standard-strength lagers, a yeast starter is recommended for higher-gravity beers or older yeast. Extended lagering, proper oxygenation, and healthy pitching rates will help maximize clarity, malt depth, and overall fermentation performance.
Produced to White Labs' professional fermentation standards, WLP833 German Bock Lager Yeast | PurePitch® Next Generation is widely used by homebrewers and professional brewers seeking reliable, authentic Bavarian lager fermentation. Its healthy cell count, clean fermentation profile, and consistent performance make it an outstanding choice for brewing traditional German lagers with exceptional malt character, smooth balance, and brilliant clarity.
