I don't know how easily you would be able to procure from these two breweries, because they are pretty small scale at this point, but Hands down my favorite is Ritual Brewing, with Hangar 24 coming in a close 2nd.

They are both in the Redlands, Ca area. Hangar makes great brews, and is a bit larger in distribution than Ritual. Ritual, though, IMHO has some of the best microbrew in California.
