Just peeked at it on website, so basically the way the law is written, the only way one could have a homebrew event is to have it at a licensed retail location. Say Martin's.
See that isn't how I see the issue. As a homebrewer, the ATC has no legal authority over me. So if I want to bring my beer into a field and invite all my friends to come drink it, the ATC can do nothing to stop me. Understandably, the ATC does not want untaxed booze in a space that sells alcohol bc the state would be losing revenue and authority. But if a place is not in the business of selling alcohol and we are not selling the homebrew, then the ATC should still have no authority over me.
I am of the opinion that if a law/permit/statue doesn't say I cannot do something, then I can do it. The ATC (through my experience) claims that since the law doesn't say I can do it that means that I cannot do it.
