starting a brewery, no matter what the size, is a HUGE pain in the a$$. you need licenses, and permits, and inspection certificates... hell, even you labels have to be approved before you can sell. here's a good blog post that lists some of this rigamarole: http://bayinghoundales.com/starting-up-a-brewery/
summary: you'd better be serious about selling beer, because once you start it's going to be a long & expensive time before you are allowed to actually sell. you need a serious business plan to pull this off, because this isn't something you can do for just a few barrels a year (unless you're independently wealthy, of course... but then why bother selling the beer).
