In making wine more accessible, information is a helpful thing. This very good article from Wine Enthusiast Magazine (LINK to WEBSITE), is a good guide to temperature ranges and the kinds of glassware to know about in serving various types of wine. While your budget may not allow you to have all of these types of glasses in your home, the temperature guidelines are something that you can manage at no additional cost – just some time and effort. And note the piece about decanting at the end.
When wines are stored properly (or even consumed just after purchase), then served at the correct temperature in the ideal stemware, you get the best value for your wine dollars and the most enjoyment possible.
