The Campo de Borja is located in northeastern Spain, in the Ebro River Valley; it is just a bit southeast of the more famous Rioja production zone. This is a very warm zone, with some moderation in temperatures coming from nearby rivers; soils are primarily limestone and clay. The red grape Garnacha (Grenache) is the star here, accounting for almost 70% of local plantings Many of the best wines are made exclusively from this variety, while there are some wines in which Garnacha is blended with Tempranillo or international varieties such as Cabernet Sauvignon and Merlot. These reds are deeply colored, ripe and fleshy, usually aged in small oak barrels. White wines are made primarily with Macabeo and Chardonnay, with some Moscatel used as well; these are medium-bodied, appealing, aromatic whites. Rosés are made from Garnacha. (Wine/Appellations)
