dude...there is not a better time to start a nano brewery than right now!
i'm currently pre-med, but i constantly lay awake at night dreaming of the possibility of beginning my own brew pub. i'm very confident that i can make A LOT of money brewing down south not because i'm a fantastic brewer () but simply because they're non-existent. i'm more passionate about medicine though, so i think i'll stick with that route.
i would HIGHLY, HIGHLY, HIGHLY, HIGHLY look into begging your brewery in the southeast. i'm in florida right now, and in the 4 years, i've seen three breweries pop up in my college town. they produce great beer and seem to be doing great.
you should see the local grocery stores over here. three years ago when i was a freshman, publix was literally ALL BMC. you were considered a beer connoisseur if you drank blue moon over here. nowadays, every publix in tallahassee dedicates half of the beer isle to craft beers.
let me tell ya, if you're going to start a nano brewery...now is the time.
