I have a few books but they can't touch a couple of selections offered online. You don't say what kind of wine you want to make but if country wines are your style, you can't beat Jack Keller's website. If you want to make grape wine, try The Home Winemakers Manual by Lum Eisenman
"The Joy of Home Winemaking" by Terry Garey. She starts you off with Welch's and yeast and walks you all the way through what you need to know for some really good wines. An easy read and I like her oddball sense of humor. Plus she's got almost as many unusual country wine recipes as Jack Keller. Anybody who can make potato-mint wine is either crazy or a homebrewing genius.
