Headed down to Cali for a few days. Have a day in Fairfield and surrounding area, definitely headed to Heretic, just wondering where else to go. Not really trying to spend the entire day in bumper-to-bumper traffic trying to get to Lagunitas (been there before), but might do it for Russian River if they have something rare on tap. Heard about a newish sour brewery in Napa? Any thoughts?
