The current issue of Gourmet has a well-written, evocative article ("A Nose for Quality", by Chandler Burr) which makes an interesting point, namely:
Drinking sweet wines like Sauternes with foie gras is a deplorable "petit bourgeois" practice, based in the "naive concept of luxury" of having "all your expensive things together". The opinion is also expressed that saving sweet wines for the end of the meal, to be consumed with dessert, is equally deplorable - they should be consumed before and during a meal, not afterwards when one's alfactory sense is shot.
Do you agree, disagree? Regardless, I do recommend the article, it's a good read.
