Wine Buying As A Gift

[Virtboy]

Someone suggested the below idea as a wedding gift and I wasn't sure how to go about buying the appropriate wine. Any suggestions are welcome:

The idea is to buy 3 bottles of wine for the married couple. One that they open on their 1st anniversary, another they open on their 5th anniversary, and another they open on their 10th anniversary. The couple I would be buying for were married in September of 2005.

Is there any guide to buying a wine that would age or be very tasty in 2010 and the same would go for a bottle in 2015? Does anyone have any suggestions on wines that would last 5-10 years?

Thanks for the help.
