Old wine is a beautiful thing. I've mentioned this on HN before, but wine is a lot hardier than most people think and it is quite possible to age many wines for a century at home. There are many factors that influence whether a wine can be reliably aged - too many to list in a comment - but if you buy a bottle of Vintage Port, Madeira, or Sauternes, it will be enjoyable for decades at the very least.

If anyone here is curious about old wine and wants to drink some together - my email is in my profile.
