There is a procedure, but I didnt look at it closely when getting a permit recently. I may still have it in my packet though so I'll check.
Not to keep talking about this, but there is nothing in the permit that discusses festivals at all. It only deals with bringing beer into a retail establishment. Since none of these festivals are typically held at retail establishments, the ATC is in a huge gray area.
My assumption of what they will say is that the festival cannot give us vendor wristbands for donating the beer. If I am correct on that guess, the future is going to be a hard sell to get homebrewers at these events. My keg of beer runs me like 30 bucks, and then you want me to buy a ticket for 35 dollars to come pour it for people. People in this thread are bitching about paying 35 dollars, think about paying 65+ to go.
As long as the ATC doesn't say no homebrew at all, Brasseurs will be at this years Zapp's, even if we have to pay more. We have too much invested now in the event to pass it up. It just may keep us from traveling to NOLA, Lafayette, Houma, Lake Chuck, etc in the future.
