Before I brewed my first brew, I read HOMEBREWING FOR DUMMIES cover to cover twice. It is about a 150 pg book, but a very quick read (lots of pictures!). The first time I read it was on a 2.5 hour plane flight.
It really does make everything pretty simple. Between that book and the simple instructions that come with extract kits from Austin Homebrew, Northern Brewer, Midwest Brewing Supply, Williams Brewing, Farmhouse Brewing, Birdman Brewing, and even Brewer's Best kits, I think I did a great job on my first few brews. You always learn and understand more once you get going, but I can't express enough what a good base this book gave me when I first started.
