Advice on something to hold for 15+ years

[Innkeeper]

First of all, let me say I fully understand the sentiment. The idea, though, is fraught with danger. The first question is will they like wine. I have four grown daughters, and none of them do. Secondly, although there are wines that last that long, the probabilty of picking the right one is comparable to filling an inside straight. Finally, you must have absolutely perfect storage facilities.

Having said all that, here are some candidates. First and foremost is Brunello di Montalcino. This is followed by Barolo and Barbaresco. Then you have Bordeaux (2000 was a particularly good year) and Upper Rhone in France. After that you have certain California Cabernet Sauvignon. Maybe others will tell you which ones.
