redwine
Oldest wine:Chateau Latour, 1er cru classe, Pauillac		1955, Bordeaux, France“Drink on special occasions…Spectacular. The essence of a wonderful claret.”“An arthritic liquid at least 40 years past its best.”
champagne
Oldest Champagne:Krug, Brut, Reims		1964, Champagne-Ardenne, France“Drink slowly. Special occasions only.”“You would need to drink it slowly otherwise you might think you were slurping some sort of cobwebby medicine.”
port
Oldest port:Quinta do Noval		1931, Douro Valley, Portugal“A real ‘national treasure’…Sublime – best this century.”“This might be interesting. Port is fortified and so lasts for decades.”
cognac
Oldest brandy:Grands Fins Bois Cognac, Charente		1878, Poitou-Charentes, France“Drink very sparingly…Excellent…superlative even. Fiery and delicious.”“Yep, though if it is fiery then it isn’t much good, as old cognac has to be mellow and luxurious.”
