About a week ago, my wife and I were cleaning out an aunts house that had to go into a nursing home. In the basement, we found a bottle of French Sparkling wine. The label says, the only English on the label, SPARKLING WINE Vve A. Aubin, Vin Mousseux, Cuvee Reservee, Produit en cuve close, French white brutsparkling wine, BRUT 1970 Does anyone have any information about this particular wine, vintage, maker????
