Dear Dr. Vinny,
The Dom Pérignon Champagne Cuvée Oenothèque—what does the word “oenothèque” mean?
—William W., Oakley, Calif.
Dear William,
Oenothèque is the French version of the Italian enoteca and German vinothek. Essentially, all these words just refer to a place to store wine or a wine library, though enoteca in particular often means a local wine shop.
The Moët & Chandon Brut Champagne Cuvée Dom Pérignon Oenothèque is a wine that’s late-disgorged after spending extra years in the cellar. In this case, “Oenothèque” refers to the place where the wine was stored for the extra time.
