Chianti

[Chuck]

I recently went to Italy and brought back a couple of wines. My friends and I enjoyed all but one bottle from a specialty shop, which I am saving. But I'm not sure if it is worth saving for a special occasion. Perhaps you can help. It is:
1990 Ruffino Ducale
Chianti Classico Riserva

(also, I'm curious if I got a good deal at $40?)
