Here is a list of recommended books that I use for homebrewing.

How to Brew

Brewing Classic Styles

The Complete Joy of Homebrewing - by Charles Papazian
This has been a terrific guide for me as I am getting started in homebrewing. The phrase that Papazian repeats throughout "Relax, Don't Worry, Have a Homebrew) is a great reminder to not stress out about homebrewing - enjoy the process! He is able to break down complicated processes into easy to understand instructions. This book will help you fully understand the homebrewing process!
