The man in the shirt that says Judge is a fellow BJCP judge, Danny Reid. The Pro-Am event for the public, where you can taste some of these beers, is next Sunday (Feb 19, 2017) 2-5 pm at Avondale Brewing.
The other event is Saturday, at http://www.goodpeoplebrewing.com/, called the Heart of Dixie Open (HODO). HODO judging was done on Feb 4, but I was unable to attend. The event for the public is Saturday Feb 18, 2017 , starting at 1 pm. A bunch of the Carboy Junkies will be pouring their beer there.
The Avondale and Good People Facebook events pages are the most comprehensive source for their events. And for the Carboy Junkies, unless you join our mailing list.
