Rapp has some great offerings. Three palms brewing also has a couple sours currently. Their Serendipity Sour is quite great.
I was lucky enough to try one of the old bottles of the "guava gone bad" a couple months ago. That was phenomenal. I hope this is true.
J Wakefield happens to be in Tampa right now.... Hanging around CCB from what I understand, so , yeah he makes some awesome sours.
