Wyeast 2112 California Lager

Brew authentic California Common and hybrid lager styles with Wyeast 2112 California Lager, a premium liquid lager yeast known for producing clean, crisp beers while fermenting at warmer temperatures than traditional lager strains. Originally selected for classic West Coast brewing, this versatile yeast retains lager-like characteristics up to 65°F (18°C), making it an excellent choice for brewers who want smooth, malty lagers without dedicated cold fermentation equipment. Each Wyeast Activator™ pack contains approximately 100 billion cells, providing enough healthy yeast to ferment a standard 5-gallon batch under appropriate conditions. Wyeast 2112 is ideal for brewing California Common Beer, Cream Ale, Premium American Lager, Baltic Porter, Märzen, and other historic West Coast lager styles.

Wyeast 2112 produces a clean fermentation profile with balanced malt character, restrained esters, and brilliant clarity. Unlike most lager strains, it performs best at warmer fermentation temperatures while still delivering the crisp finish expected from a traditional lager yeast. Its high flocculation promotes excellent clarification, making it particularly well suited for malt-forward recipes where smoothness and drinkability are key. This strain is not recommended for cold-temperature lager fermentation, as it was specifically selected for warmer California Common-style brewing.

This liquid lager yeast features high flocculation, 67–71% attenuation, and an alcohol tolerance of approximately 9% ABV. It performs best between 58–68°F (14–20°C) and is packaged with approximately 100 billion cells for dependable fermentation performance and consistent brewing results.

For best results, store refrigerated between 33–38°F and do not freeze. Pitch into well-oxygenated wort and ferment within the recommended temperature range. One Activator™ pack is suitable for many standard-strength 5-gallon batches, while a yeast starter is recommended for higher-gravity beers, older yeast packs, or whenever additional cell count is desired. Maintaining fermentation temperatures near the lower end of the range will produce the cleanest lager-like profile while preserving the strain's signature malt-forward character.

Trusted by homebrewers and commercial brewers alike, Wyeast 2112 California Lager delivers dependable fermentation, excellent clarity, and the distinctive character that made California Common beer famous. Its healthy cell count, reliable performance, and ability to produce crisp, malty beers at warmer temperatures make it an outstanding choice for brewing traditional West Coast lagers and other hybrid beer styles.
