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.


We include complimentary ice packs with ALL liquid yeast orders (if required), but cannot guarantee that the ice packs will stay cold during transit, and thus the yeast can potentially be exposed to hot temperatures. We highly recommend ordering dry yeast during the hot summer months or if you are ordering from a warmer climate. Many times during the winter an ice pack is not needed so we make the determination based on current temperatures and the destination!

Fast Shipping!
I love the fact GF processes my orders and ships items out without delay. If I were to offer a suggestion though, it would be beneficial to me if you had a label or a note reminding us that there is temperature sensitive ingredients (yeast) in the box so we don't just haphazardly set the box in the garage for four days awaiting brew day. I forgot the yeast needs to be removed asap even if I'm not brewing upon delivery. My bad!
