champagne
Oldest Champagne:Krug, Brut, Reims		1964, , 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 :Quinta do Noval		1931, , “A real ‘national treasure'…Sublime – best this century.”“This might be interesting. Port is fortified and so lasts for decades.”
cognac
Oldest :Grands Fins Bois Cognac, 		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.”
