I was told yesterday evening about a 1921 that showed beautifully on New Year’s eve, 2011. I don’t know if the domaine existed in its current form back then, but my understanding is that it was a Vouvray made by one of Francois Pinon’s ancestors at least.
Back in 2001 at the Dressner/Coad birthday party I had the pleasure of tasting a 1959 Huet LHL Moelleux and a 1959 Pinon Vouvray side by side. The Pinon was clearly the better wine (and the Huet was no slouch).
