Most lager strains require fermentation below 55°F; Wyeast 2112 performs cleanly at 58–68°F, producing malty, brilliantly clear beers with true lager character.\u003c\/p\u003e\n\u003cp\u003eThis is the traditional strain for California Common (also known as steam beer) — a distinctly American hybrid style that uses lager yeast at ale fermentation temperatures, developed in San Francisco during the Gold Rush era when cold refrigeration was unavailable. Its high flocculation means the yeast drops out of suspension quickly, producing naturally clear beer with minimal effort.\u003c\/p\u003e\n\u003cp\u003eNote: Wyeast 2112 is not recommended for cold temperature fermentation — it performs best within its 58–68°F range and should not be used as a standard cold-fermented lager yeast.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFlocculation:\u003c\/strong\u003e High\u003cbr\u003e\n\u003cstrong\u003eApparent Attenuation:\u003c\/strong\u003e 67–71%\u003cbr\u003e\n\u003cstrong\u003eAlcohol Tolerance:\u003c\/strong\u003e 9%\u003cbr\u003e\n\u003cstrong\u003eFermentation Temperature:\u003c\/strong\u003e 58–68°F (14–20°C)\u003cbr\u003e\n\u003cstrong\u003eSpecies:\u003c\/strong\u003e \u003cem\u003eSaccharomyces pastorianus\u003c\/em\u003e\u003c\/p\u003e","brand":"Craft a Brew","offers":[{"title":"Yeast only - no ice pack","offer_id":44109671694401,"sku":"IG-Y-L-WYST-2112CALAG","price":13.99,"currency_code":"USD","in_stock":true},{"title":"Insulated mailer + 1 ice pack","offer_id":44109671727169,"sku":"IG-Y-L-WYST-2112CALAG-ICE1","price":15.49,"currency_code":"USD","in_stock":false},{"title":"Bubble mailer + 2 ice packs","offer_id":44109671759937,"sku":"IG-Y-L-WYST-2112CALAG-ICE2","price":17.49,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0168\/3816\/files\/Wyeast_Homebrewing-Front.png?v=1749238788","url":"https:\/\/craftabrew.com\/products\/wyeast-2112-california-lager","provider":"Craft a Brew","version":"1.0","type":"link"}
