I think we are required to spend $1000 per year for ABC lic. for the right to sell, not to mention Fed. and State taxes. There's also a background check along with all kinds of local regs I am sure aren't included in that bill (for instance, we were required to have "food grade lights" which costs well over $5K. They were cheap compared to the sewer upgrades the city made us install.) We have one guy who's job it is to take care of all the TTB and local regs. The TTB is not too bad, but they require approval of everything, and you can't sell without approval.. Quite frankly, on the homebrew level, it is going to be way, way, way more trouble and money than it is worth.
