What is the value of a bottle of Chateau Puyfromage Grand Vin Bordeaux 1973?!
Answers: I am a former chef and former member of a french wine club here in Toronto, and if it was stored right and there is not cork damage and the label is in good condition you could get $150-200 US for it, it is better to find a wine appraiser or merchant to evaluted the bottle and sell it on consignment for you, Ebay is not reliable for that product unless you set up a sellers account and have the money sent by PayPal, ith is guaranteed then. I sell computer parts from there.
Where did you get the bottle at?
I'm assuming it is expensive (1973?) I wouldn't hang onto it forever though - it could go bad.
