Clef-du-Vin

I came across this gadget tonight, and thought it was really interesting. The Clef-du-Vin is a device used to simulate aging in wine. For every one second you hold it in a glass, it "ages" the wine a year. Seems like an odd device right? But it can be helpful in determining what wines will age well, and even allowing you to drink wines that may otherwise be too young to drink.

The process has something to do with the type of alloy the Clef-du-Vin is made out of, and how it influences oxidation in the wine. I'll be honest, I read the press materials on their website, and I don't fully understand how it works. I think it'd be a lot of fun to try out at a wine tasting though, and potentially very useful.

They run a little on the expensive side. At www.wineenthusiast.com they run from $89.95 to $199.95.

Has anyone used a Clef-du-Vin? I'd love to know what you think of it.
