Pommery Grand Cru Brut

Pommery Champagne
The label has broken so much that it is impossible to see the vintage.
However, it is stamped 68 at the bottom (There is also stamped 2 at the bottom).

Therefore, my best bet, after looking a bit at the house and what vintages they have published and more, is that it is either a vintage 1961 or 1964.
This also agrees very well with "the secondary fermentation" or "le dosage".

It has a nice stand and color.

Here is a little link to the house, WineSearcher m.m.
