Perhaps our most popular lager strain, California Lager yeast is a very versatile strain that makes wonderfully clean beers without cold fermentation temperatures. In fact, Wyeast states that this yeast is not recommended for cold fermentation. With a temperature range between 58°F and 68°F, beers made with this strain purportedly keep lagers characteristics up to 65°F, though beers fermented warmer than this may also be very lager-like as well. It is known as the quintessential yeast in the production of California Common beer, coming from the California brewery that may have saved the style from being lost to history. Malty and highly-flocculant, this strain behaves like a slightly-cool fermenting ale yeast while producing extremely clear lagers.
