Just a very quick overview of the issues:
Alcohol is taxed federally, at the state level, and in some instances the local level. So you must file with the state, feds, and locally so they can collect their taxes.
Beer cannot be brewed residentially. Detached garage *might* be an exception, but you'd have to be zoned for industrial.
Beer is a food product and must conform to federal, state, and local food production guidelines and laws. You will be on a first-name basis with your local food/health inspector.
You'll want to form a business to do all this stuff. You can easily form an LLC to do it, but federally you'l be considered a sole proprietorship (assuming you go it alone, otherwise you'd be considered a partnership). It's better to form an S Corp because those are recognized federally as corporations.
You might want to consider contracting the brewing to another brewer and instead forming a company of your own to find the brew and collect the sales. Contract brewing varies greatly from state to state, but some of the more famous (Boston Beer Company and the Brooklyn Brewery) breweries started out as contract companies sourcing their brewing to larger brewers.
Sounds like you have a great beer there. Good luck with it!
