"Thanks for emailing, and we're honored to hear you're taking a stab at brewing your own version of our California Lager! We keep Cal Lager at 58 degrees F (give or take a degree or two) for about three days in primary fermentation, after which we crash it to 35 degrees F and let it ferment at this temperature for three weeks.
We also krausen the beer before we crash it. We aren't entirely sure how this would work on a homebrew scale, but a few of us did kick around the idea of approximating our process by fermenting a small amount of malt extract for 12 hours or so to introduce before crashing the rest. We're not sure that you'd need to do any krauesening to re-create the Cal Lager taste, though, so you should be fine even if you skip it.
Happy brewing, and let us know how the beer turns out!
Cheers,
Anchor Brewing Company"
