Thoughts from an old fart brewmaster:
Where do you live, what experience do you have and what financial obligations are you under?
Unfortunately the brewing business is not financially strong. Most brewers make just enough and most breweries are stretched pretty thin. Also, there are not a lot of opportunities, seeing how it is generally a brewer who starts or is an original partner in a brewery operation. Some areas have more opportunities, given a greater number of breweries, but still it is hard to get your foot in the door.
Possible tracks are volunteering to do grunt work. No pay, but you get in the door so others possibilities might come about. This gives you hands on experience so when you try for a paid position you have something on the old resume. Another whole avenue is education. Go to school at Siebel in Chicago, or UC Davis. Go to England as a brewery slave, go to Germany.
The bottom line in all of this is brewery work is hard work. I know only a few Gentleman Brewers, most have sore backs, sticky hair, and are really sick of hoppy, malty beers. I wouldn't trade my years as a brewmaster for anything. I loved it, but it was hot in the summer, cold in the winter, and people very freely tell you how much your beer sucks.
Then again, you go to the Great American Beer Festival and you are part of the inner world. If you win a medal there you feel like a God.
Move ahead with your eyes open, but remember, when you become a pro it is no longer a hobby, it is a job. It took almost 3 years for me to get back to the kettle after I left my brewery, but in the end, I still love it!
