Read, but don’t obsess. You aren’t going to brew a perfect beer the first time, and there is only so much you can do with your first batch. Pick a book, and read it. The two most common are How to brew by John Palmer And The Complete Joy of Home brewing – Charlie Papazian. They are different takes on brewing, read a few pages from amazon, and pick the one that suits your style, and read it. I read and read and read, and listened until I was filled with crazy ideas, and worried about doing it perfect. I didn’t understand what I was reading. Just pick a book, read it, and get a bad first draft done.
