I have just enjoyed a nice glass of Spanish wine with dinner and it reminded me that when we returned from the first year in Oñate, the only Spanish wine available in Boise was Siglo, a Rioja that came wrapped in in burlap. It was decent, but many of us began searching for something similar to the chiquitos that drank when we made the rounds of the bars. Of course, that wine was nothing to write home about (although we all did, not because it was good, but because it only cost two pesetas a glass), but we developed a taste for it. The closest wines we found were low-end cabernets and zinfandels that we brought to potlucks and spaghetti or paella dinners that we organized in the mid to late 70"s.
Later more wines became available here, mostly Riojas, and some from Navarra and Catalunya. We tried them all, yet we kept a taste for basic red table wine. Carlo Rossi was usually served at dinners and wedding receptions held at the Basque Center, and it was also preferred by my Basque father-in-law who spent every summer with us in the U.S. from 1985 through 2000.
Now there are many, many Spanish wines sold in the United States. They have begun labeling them (at least the less expensive ones) by the kind of grape, like tempranillo, garnacha, etc. instead of using the name of the region. The big name Rioja wineries still market their traditional blended versions with the heavy oak flavors as "Rioja" rather than varietals, but inexpensive Spanish wines with clever/pretty labels naming the grape rather than the winery are all over the place.
Recently I have enjoyed wines made with the monastrell grape (by itself or as the major variety). I have heard that the tempranillo grape grows everywhere in Spain, but that its quality varies greatly. And I had a couple of bottles made with garnacha that I did not like very much.
I wonder if any of the SLT folks continue to try Spanish wines? I also wonder what Jamie has to say, since he is quite an expert on the food and drink of Spain (and he probably would be even if it wasn't his job!)
