I have a bottle of 1970 vintage port Borges and Irmao, purchased in Portugal in 1983.Does the bottle have a value, and would it be OK to drink? We have been keeping it for a Special Occasion but I am concerned that it may have past it is best. I am in the UK; the bottle has been laid in a cool dark cellar.
