Wine appreciation is just that. Appreciation. And appreciation is something you learn over time, whether it is art or food or women, etc.
As a younger man, the only wine I liked was Miller, the Champagne of Beers.
But after living in France for a number of years, and specifically in Burgundy, I have learned so much about wine that I have a very high appreciation of it. This is good and bad. The bad part is that I can no longer drink poor quality wine. And most of what you find in the world, as a traveler, is poor quality wine unless you pay a lot. In France, and a few other special places, you can get very good quality wine for a decent price if you know where to look.
Some places I go I simply don't drink the wine. I would rather drink beer. But if I have a chance to drink a very good wine, I always go for it. Note however what I mean by very good wine doesn't mean famous brand or expensive bottle. In fact where I live, the best wines may not even have labels.
