I'm starting to very slowly restock my wine rack[0] and every time I go to the grocery store I'm faced with a rather vast array of wine that I don't have the time, money, or liver to fully explore. It's a bit like choosing a linux distribution. Once you've tried a few linux distributions you have a vocabulary to describe common features and differences, but there are still a million flavors out there that you'll never (or at least I'll never) have had the time to try out. And then another year will have passed and the flavors will be different again. Of course, the bright side is that with wine you don't have to reformat your hard disc when you switch vintage.
