+1 to above.
You might be able to get a position at one of the very large breweries, but you're probably better off looking into a brewing equipment company. A ME's expertise would be more useful there.
Furthermore, my understanding after talking to Eric (the brewer at Rochester Mills in Rochester, MI) is that getting into most smaller breweries is a matter of right resume, right time.
Brewers, assistant brewers and other brewery/bar employees generally aren't paid very well, also. As a junior, I'm sure you've looked up the average starting salary for MEs. Take the average pay and divide it in half, you might be able to find that.
