Cigar city. Any beer will do but ipa is my favorite. They have a white oak version too that's also awesome.
If you find yourself going west to Clearwater definitely stop in Dunedin and check out the Dunedin brewery. There's another nano down town too but i can't pull the name atm...
I've been going down there every year for almost 30 years and those are always my go-to's
+1 on Dunedin. Cool little joint and there's a fresh fish/seafood market next door, so you can grab some brews and food for lunch, then run over for some fresh seafood to make for dinner. Looking forward to heading down there in the fall.
I spent time there in December and my favorite was Rapp. It's across the bay closer to St. Pete, though. I tried 10 of their beers and 8 of those were winners.
