Delong's Wine Info is a great wine site. If your new to wine appreciation this is an excellent resource for gaining a greater appreciation of wine. With the very appealing slogan of "Learn by Drinking!", which I agree with wholeheartedly, their web site is filled with useful information.

De Long's offers a Wine Grape Varietal Table that is incredibly useful wall hanging reference that is a useful reference for professionals and novice alike. It shows how each grape produces the various wine that are available.
