The wine was unrecognizable as Chassagne-Montrachet but was not poison and made good gravy for our roast chicken. It tasted, as Mr. McInerney said it might, like Sherry, due to premature oxidation as Burgundy lovers now know all too well.
I have had only excellent wine from Chambers Street Wine. Now I am going to put them to the test: Can they recommend a Meursault or Chassagne-Montrachet. If they can't, I shall probably never buy wine anywhere else—they must be honest people. If they can recommend one, and it tastes like Meursault, I shall certainly never buy wine from anyone else. At least that is what I shall feel like for a while. (But no, how could one give up Yannitelli's purring descriptions of a Bandol, or Viscount's $8 Chilean Cabernet Sauvignon, $11 anywhere else, and the always warm greeting at Artisan who recommended an $11 Soave after I asked for something to go with the last pesto of the season and it was exactly right for the dish?)
When I have found this bottle that tastes like white Burgandy I shall photograph it.
Meanwhile here are two people having a good time over a glass of something, taken in the 1970s in England at a wedding.
