This is totally OT, but I thought since it seems some on this board are experts in the field of wines and the like, I would ask. (And I do not feel like becoming member of yet another chat board.) Mods feel free to delete if it seems way too OT.

I was cleaning out the liquer cabinet in my family's place in the province, and I came accross quite a few bottles of seemingly very old and mature French wines. Being a complete idiot in such matters (the only wines I know much about are South Africa and Washington), I have no idea whether they are vineger, whether I should try to sell them, whether they would be worth opening to drink...

Four wines of several bottles each that seemed the "best" are:

Chateau Grand Barry
Appelation Lussac-Saint Emilion
1982

Buzet
Appelation Buzet
Mise en bouteille au Chateau
1986

Le Trochet (Grand Vin de Bordeaux)
Appelation St. Emilion
Grande Cuvee Exceptionnelle, Monopole
1973

Chateau Latour (Grand Vin)
Appelation Paullac
1981

So what are your verdicts? Or is there anywhere I can go for advice?
