The practice of decanting wine makes for a most impressive ceremony, but it is not always appropriate. The purpose of decanting wine is to separate the beverage from sediment that accumulates after a long cellar life. It also serves to aerate the wine. Decanting is only appropriate for red wines over 10 years old—
particularly Bordeaux Clarets and California Cabernets. Burgundy wine–makers, however, discourage the practice and suggest that if you feel you really must decant, do so as close to serving time as possible. Red wines that are not decanted should still be allowed to breathe, however, so by all means let a fine red aerate for 15-20 minutes before serving.

This stack is an introduction to the five major wine making regions of the world and the wines they make.  It is meant to familiarize the novice with the districts of Bordeaux, the difference between sherry and port, what food best accompanies
certain wines, and —because there is a certain snob-appeal attached to wine but also because there is so much to be learned by sampling an area's best and most distinctive offerings—what the most widely-judged "Bests" of various regions are.  
The real work -if it can be termed such- is for the reader to undertake. It is the task of seeking out and tasting the wines mentioned , of learning for themselves what is meant by an "earthy" flavor or a "fruity" bouquet. Of discovering for himself what the wines of Medoc taste like and what makes them distinct. Remembering the distinctive qualities on a later date and realizing what makes them different from the reds of St. Emillon. And because so much of the joy of wine-tasting is discovering a new wine for yourself, I have often listed but not elaborated upon additional regions, or estates for the reader to investigate for himself .
One final word of advice: Don't be afraid to try a "Best" or two. The education they offer are well-worth the price, and there are many restaurants now able to offer even fine vintages by the "glass" or even by the "taste".  Glass servings are seldom more than a $5-6, and tastes are generally $3-4. Check the fine restaurants in your area to see if any offer this wonderful way to inexpensively expand your wine repertoire. [Note to New Yorkers: The Wine Bistro atop the Novotel in the theater district has an extensive tasting-wine list and informed waiters to help you make your selection.]  
So read on, sample, savor, remember and compare, and above all, ENJOY!
