Not a declared vintage. A Colheita (barrel aged single harvest) Port is a good alternative for this vintage, and would be a lovely 68 year old wine gift for a birthday or anniversary celebration this year. 1951 Single Quinta ports may still be drinkable, but are in short supply.
A very good year for Italian heavyweights such as Brunello and Barolo, 1951 wines from Italy are rare and in short supply.
Unfortunately, bad conditions led to a poor year for Bordeaux.
