Folkiedave, while I was in Spain last Spring, I had several reds under the same bodega label, something like Alfonso III. These wines were available at Corte Ingles Supermarkets, and ranged from the "III" up to VII, and with prices and quality that increased as the roman numerals went up.
Any clue as to their identity?

I am the possessor of a bottle of true Amontillado from Bodegas Alvear in Montilla. This is wonderful, warm, nut-brown stuff, and Alvear is the originator, making it in the same huge earth-sunken ceramic tanks since the early 1800s, probably the same tanks that were decanted to provide the famous casque commemmorated by Poe in his story. Apart from the sherries, though, I haven't cared for Spanish whites...they all seem to derive from the sherry grape.
