I live in New Orleans and my wine collection (about 500 bottles) has undergone a major catastrophe because of Katrina. The wines reached a steady temperature of just under 90 degrees for over a month. This is obviously not good, but how bad is it? Many of the wines still taste quite good. But I don't know what to do with wines that need aging (i.e. 2000 Bordeaux). Should I give up on aging any of them and drink them now? I may have to decide whether to sell them all cheaply to the insurance company.
Also, on some of the corks I see small crystals. Anybody know what they might be?
