Is there any way to date vintage bar end plugs? I think they would be too new for carbon 14 dating and, IIRC, the last bottle of Chateau d'Yquem I guzzled (bought with the proceeds of selling the Herse triplet) didn't have a year on the cork.
Of course, one should use correct corks from regional wines, even though this places Scandinavian frames at a disadvantage.
