Wine management software can produce an instant, detailed inventory of a collection and sort it, for instance, by grower, region or drink-by date. Most are web-based now too, so you can access your collection from handheld devices when you're out and about. Sounds cool, if you know, you have so much wine you can't keep track of it. Me? I know exactly what's in my wine "cellar," about four reds worth saving and several more worth drinking right now.
