Rioja

Rioja is a wine region in Spain, with denominación de origen calificada (D.O.Ca., "Qualified Designation of Origin," the highest category in Spanish wine regulation). Rioja wine is made from grapes grown in the autonomous communities of La Rioja and Navarre, and the Basque province of Álava. Rioja is further subdivided into three zones: Rioja Alta, Rioja Oriental and Rioja Alavesa. Many wines have traditionally blended fruit from all three regions, though there is a slow growth in single-zone wines. Located on the western edge of the region and at higher elevations than the other areas, the Rioja Alta is known more for its "old world" style of wine. A higher elevation equates to a shorter growing season, which in turn produces brighter fruit flavors and a wine that is lighter on the palate. The region of Rioja Alavesa is in the province of Álava in the Basque Country, on the northern bank of the River Ebro. Despite sharing a similar climate as the Alta region, the Rioja Alavesa produces wines with a fuller body and higher acidity. Vineyards in the area have a low vine density with large spacing between rows. This is due to the relatively poor conditions of the soil with the vines needing more distance from each other and less competition for the nutrients in the surrounding soil.
