For Lagers: "Brewing Lager Beer", Noonan - very detailed, technical. "The Complete Handbook of Homebrewing", Miller - very comprehensive, but perhaps a bit out of date. "AHA Classic Beer Styles" series - any of the lager style books will tell you what you need to know. If you want technical, any George Fix book will do the trick. -- -- Michael Valentiner, Minneapolis, Minnesota mpv(a)yuck.net
