I find that to really know a subject, you have to absorb many viewpoints on it.  With something as personal as homebrewing, that is certainly true.  I have many more on my wish list, but here is my collection so far.  If you have something to recommend, let me know (comment below) so I can add it to my wish list.

• The Complete Joy of Home Brewing, by Charlie Papazian.  Start here.  This is probably the best getting started guide I have seen.  It starts assuming you know nothing of yeast and continues into advanced topics.
• Brewing Better Beer, by Gordon Strong. This one took me to the next level of understanding what I was doing and really gave me the edge to think for myself.
• Designing Great Beers, the Ultimate Guide to Brewing Classic Beer Styles, by Ray Daniels.  This is a must for anyone that wants to craft their own recipes.  It really gave me a good understanding of how to set and hit my target beers.
• Dave Miller’s Homebrewing Guide, by Dave Miller.  This was recommended to me as a great book to help me diagnose and discern specific flavors in the beer.
• A History of Beer and Brewing, by Ian S. Hornsey.  I got this to take a more serious look at history.
• Wassail! In Masers of Mead, by Robert Gayre.  This one has a great historical approach and some awesome recipes.
• Strong Waters, by Scott Mansfield.  I bought this specifically to help a friend make an alcoholic ginger beer.  It has some wine recipes I still want to try.
• A Sip Through Time, by Cindy Renfrow.  This is a well-respected and just plain awesome guide to historical beverages and how to make them.
• Sacred Herbal and Healing Beers, by Stephen Harrod Buhner.  Medicinal herbs go way back and everyone knows that beer is good for you, right?
• German Wheat Beer, by Eric Warner. I got this for some further research on brewing with wheat.
• Brewing with Wheat, by Stan Hieronymus.
• The Joy of Home Winemaking, by Terry Garey.  I got this to learn more about the differences between making beer and wine.  It was helpful.
• The Complete Meadmaker, by Ken Schramm.  This is a good guide if you really just want to focus on the making of mead, which I did for quite some time.
• Cider, Using & Enjoying Sweet & Hard Cider, by Annie Proulx & Lew Nichols.   There is certainly a lot to learn about apples.  I’ll consult this book again when I start pressing my own.
• Craft Cider Making, by Andrew Lea. This inexpensive guide to cider has some additional insights.
• Cooking and Dining in Medieval England, by Peter Brears.  This had some great insight as to how brewing fit into the medieval life.
• Homemade Root Beer Soda & Pop, by Stephen Cresswell.  I used this to experiment with some Ginger Ale and Root Beers.
• Beer in the Middle Ages and the Renaissance, by Richard W. Unger.  I purchased this one to look for more clues in the designing of recipes that give historical nods.
• Early American Beverages, by John Hull Brown.  This one was given to me by a friend and has some great recipes to try.
