You need to visit the closest brewery and ask for a tour. Ask questions. A tour is worth a thousand posts. I could easily answer all your questions but if you are seriously considering opening a brewery and havent done a bunch of tours and asked a hundred questions you arent doing your home work IMHO. Not trying to be a smart ass. Ive been brewing proffessionaly 12 years and have turned down a tour once or twice. Given tons and answered the same questions over and over again gladly. Ive let wanna be brewery owners spend a whole shift watching the whole process answering all the questions and offering advice. This is Probrewer for a reason. Im just saying that if you are serious put some legwork in and check the real thing out. It aint that complicated.
