I can hardly believe it's taken me so long to finally get around to updating this post and getting to brew this recipe again. Today I've been reading a lot about two very special types of yeast White Labs WLP810 - San Francisco Lager™ and Wyeast 2112 - California Lager™. The White Labs WLP810 - San Francisco Lager™ strain was categorized by
Chris White as being a true Lager strain that happens to tolerate 58°-65° F fermentation temperatures very well. Anyone familiar with Anchor Steam knows that it relies heavily on the clean Lager fermentation and malt character produced by WLP810 when fermented at near Ale temperatures. They know how well the Northern Brewer hops work with the flavors produced by the yeast and the malts in the recipe.
This time around I plan to brew a 10 gallon batch using 2 pounds of Crystal 80 and 20 pounds of Pale Ale malt with an 8 ounce mix of Northern Brewer and Cascade hops. It's very similar to the recipe I brewed this Spring but this time I plan to pitch a yeast strain that's more suitable for this style of beer. According to
Jamil Zainasheff's yeast calculator and what other home brewers have posted the pitching rate for the WLP-810 is a 'hybrid' somewhere between an Ale yeast and a Lager yeast.
The California Common style is a 5% ABV session beer and since it's a hybrid it'll need 500 billion cells to hit the correct pitching rate, it's interesting to know that if it were a Lager yeast fermenting at 50° F the pitching rate would need nearly 800 billion cells. I plan to buy 2 packs of WLP-810 and add each of them to two liter starters, according to the chart in the book 'Yeast' a package of 100 billion cells will grow to 240 billion cells when spun on a stirplate. It feels pretty good to be getting back into the game again.
