You may have heard that a lot of the hullaballoo over wine tasting is a lot of hype. For example, just tell your guests that their vino is primo, and they'll enjoy it more. Here's another trick: just throw a year in front of it when you're describing it. (We particularly recommend the '16 Franzia.)
There's one bottle in the world that we'll probably never know if it lives up to its one-of-a-kind vintage. The Speyer bottle is at least 1,650 years old, and what's more, its contents are still sloshing around inside (you might not want to drink it, though).
