I enjoy good wine, and enjoy learning more about it.  If you do as well, here are some interesting links:

•  Robert Parker's Wine Links Page is a list of many other links.
•  Merchants Wine & Spirits is a good wine store, with free weekly tastings, in downtown Boston.
•  wine.com  is a great online wine store; I rely on their recommendations and tasting notes.
•  California Wine Club is a good wine-of-the month program; you subscribe and they send you two bottles, their selection, once a month.
