2000 wine that can age

[nfike]

I would like to purchase a bottle of 2000 wine for a friend. They were married last year and my friend stated that she had purchased a bottle of wine that she intended to open on their 25th anniversary. Though I don't know a great deal about aging wines, this was a sweet white (I believe niagara) that I am fairly certain is not intended for aging.

I am mainly interested in a wine that will mature in 25 years. It definitely does not need to be drinkable now. As a person's taste in wine is likely to change a great deal over 25 years, I'm not too concerned as to the kind of wine. I'm mainly looking for something that is a safe bet to be ready to drink on their 25th anniversary.

Any suggestions would be appreciated.

Also, any storage tips would be helpful as well. My friend has a basement, and I intended to suggest that she keep it in a cupboard within the basement. Out of light, and cool.

Thanks much!
