Making Sherry

In my Chinese weblog, FZ asked me about sherry. Her description got me interested and I did some search on the net. Found a little interesting article on the making of Sherry, along with it a brief history of Sherry was given as well.
Making Sherry

The fact that sherry requires “aged sherry … to ‘educate’ a younger wine” sounded familiar to me. I remember hearing a similar process while visiting Champagne cellars. But I don’t believe that is how Champagne is made. I wonder if there is another wine that goes through this similar process by using an aged wine to educate a younger wine. Whiskey, perhaps? If not, then one of the cellars I visited must have been producing sherry on the side! :O But which one?

Now i’m curious…

Then again, it probably won’t be called Sherry. It sounds like Sherry has a similar geographical prestige/restriction just like Champagne.
