Another option( which is what I would do if I was in your situation) which would seem to make a lot of sense with a lot less risk would be to get a job in the business world when you graduate and make as much money as you can. It seem logical that with your degree you could make TWICE the salary right out of college than you would make in the brewing industry. Afterall you're going to need some money to get yourself started and/or get rid of those student loans would also be helpful.
Starting now, get your hands on anything and everything written about the world of beer,learn, learn,learn. Start homebrewing as soon as you can. Talk to anyone and everyone related to the world of brewing/beer, you can learn something from everyone whether they be a homebrewer,accomplished professional,delivery driver for a local distributor even the bartender at your local pub. Think beer,talk beer, be the beer, be passionate and people will take notice.
Once you've graduated and are working "in the real world" then start thinking about taking a an online brewing course like ABG, as you can do this while you keep your job and bring home the bread. Stay involved with the industry no matter what, whether it be volunteering at a local brewery a day a week, for festivals or whatever. Seek out and try as many different beers as you can, a part time job in a good beer bar/store would make them very accessible as well as economical for someone straightening out their finances.
Remember you're still very young, I personally don't know anyone who started their own brewery before the age of 30. If this is what you want to be doing the rest of your life( and time will only tell on that one) then you're in it for the long haul, so jumping into the business ASAP shouldn't be a goal. A business that fails to plan should plan to fail. Research every little thing down to the penny, figure out what you need for capital,then of course double or triple it!
