Tom:
Believe it or not I would start with the "Wine for Dummies" book. It really is an excellent book for someone starting from scratch. They also have a "White wine for dummies" and a "Red wine for dummies." I would start with the generic wine for dummies.
Even with my knowledge of my wine, I still go back to the dummies book for information.
As you start to advance yourknowledge you may want a more detailed book. There are two good ones. Hugh Johnson's World Atlas of Wine and the Larousse Encyclopedia of wine.
It also wouldn't hurt to subscribe to a wine magazine. It helps keep you abreast of recenet trends, vintages, and prices.
Welcome fellow oenophile. Soon you'll be addicted too.
