For a long time I've meant to attack this systematically and finally 'cracked the codes' of the state ABC site. Here's a map of licensed microbrewers, brewpubs and home brew suppliers in the county:
Due to the higher costs of meeting county health dept requirements, most microbrewers don't serve food but most have 'tap rooms' for tasting. Surprisingly, there aren't that many places categorized as brewpubs.
I challenge one and all to Drink Local Brews and show us your (regional) maps!
