I thought about this pretty hard as well (was pretty set on quitting my job and moving to Davis)....
But then I factored in the money. Brewers (even Master Brewers at big craft breweries) don't make much. You will most likely cap out at about 50k and will start out much much less than that.
The only way to make any money in brewing is to have your own brewery, and that is even hard to make money at. If financials are not as big of a concern to you, then go for it. You are most likely not going to get a job as head brewer at Dogfish right out of school; but don't get discouraged. Work your way up from bottle filler to head brewer.
Talk about loving what you do!!!!
