http://www.lexisnexis.com/hottopics/gacode/ Check out Title 3. I think the guys at Burnt Hickory are a nano. In GA a brewery is a brewery. The only exception is for brewpubs.
We brew on the north side near Canton the 3rd Friday of every month. We normally have 5-7 styles on tap. If your close come on out. We post the info on Facebook on our page, Reformation Brewery and we also send out email updates via our website reformationbrewery.com I'm not an expert but I've spent a lot of time looking at the GA laws for breweries. We are going to start a brewpub by the end of the year or early next.
