Two too old Pontet Canet's?

1978 Château Pontet Canet;
B elevl fill, to old and tired.

1971 Château Pontet Canet;
Cruse bottling. Again B level fill and tired.

I was a bit surprised by this. The provenance of the two bottles is not known. Even if the quality of Pontet Canet has exploded over the last two decades, I was very surprised. I have not tasted that many great 71's, but the 78 should be alive and kicking. I wan't to put it in the book of ruined by storage. Unfortunatelly I have never tasted any 70's Pontet Canet to have as reference. But from other and similar quality estates, they should both have performed well above this.
