California Lager Yeast | Wyeast 2112 Yeast

California Lager Yeast | Wyeast 2112 Yeast Classic Steam Beer Yeast for Fermenting Lagers at Ale Temps Wyeast 2112 California Lager Yeast is a unique hybrid strain originally sourced from a historic San Francisco brewery. This yeast is essential for brewing California Common (Steam Beer), as it produces the clean, mildly estery, and malt-forward profile expected from the style—all while fermenting at ale temperatures. Ideal for brewers without temperature-controlled fermentation setups, this strain offers lager-like characteristics with the simplicity of ale fermentation conditions. Expect a moderate fermentation rate with low sulfur production, high flocculation, and good clarity in the final product. Wyeast 2112 is not only the traditional choice for Steam Beers but also works well in malt-forward lagers, amber lagers, and experimental hybrid styles that call for clean fermentation with lager smoothness. Key Characteristics: Flocculation: High Attenuation: 67% - 71% Fermentation
