People in the US might want to know that Catalan company Borges has reached an agreement to sell its olive oil and vinegar through Wal-Mart. Borges is headquartered in Tàrrega, about 15 kilometers up the road from my wife's hometown, Vallfogona de Riucorb. It's a pretty good-sized privately-owned company, doing more than €500 million a year in business, and it's a respected brand name in Spain.
In Spain Borges has a line of varietal olive oils that are especially good, and I particularly recommend the arbequena variety, produced mostly in southern Lleída province.
Vallfogona de Riucorb is also in the Costers del Segre wine denomination of origin area. and if you ever see any wines from there, try them. I imagine Raimat, which belongs to the major cava producer Cordoniu, is sold in the US; they make a very good and inexpensive cabernet sauvignon.
