Big +1 on Fieldwork. Love their Sea Farmer, a sea salt grapefruit IPA. The folks at Mikkeller told me the brewer was the one that also developed Grapefruit Sculpin at Ballast Point, and this is even bigger in grapefruit flavor. Their Coconut Milk IIPA is also delicious and so hard to describe–creamy, strong, tropical deliciousness.
I missed out on the Hot Chocolate when I was at Tap 25 in Livermore; it was already kicked! They brew it with TCHO chocolate and spices.
For sours, Rare Barrel, a couple of miles south of Fieldwork, is a must try. Unfortunately you can’t do growler fills unless you’re in one of their membership clubs. They have some bottle releases each week only available at the tasting room, however.
