The savory red wines of Spain are brooding and complex. They are typically a little lighter than a California Cabernet, but richer and fuller than a Pinot Noir. The most commonly used red grapes in Spain are the lovely Tempranillo grape and the rich Garnacha, but Cabernet Sauvignon is starting to get popular as well. The main grape in Spain is Tempranillo, which is followed closely by Garnacha. In the past, Spanish reds were know to be worthy of aging for decades and were very expensive because of this. Now that technology is more available they are making more affordable, fruitier wines.
