This DO area (Empordà in Catalan) is located in the far corner of north-eastern Spain on the Mediterranean coast in the region of Catalonia and borders on the French Roussillon. The area is considered one of the cradles of Spanish viticulture. The vineyards cover 2,300 hectares of vineyards on limestone soil and are located 200 metres above sea level, often in crater-shaped valleys (see under Conca). The climate is Mediterranean with cold north winds. White wines are made from the varieties Chenin Blanc, Macabeo, Muscat Blanc, Parellada, Riesling, Xarello as well as Chardonnay and Gewürztraminer. Red varieties are Cariñena (Mazuelo), Cabernet Sauvignon, Syrah and Tempranillo. Rosados (from the Cariñena variety) and traditionally also Rancios, which still have a high alcohol content, are produced for the most part. Cava (sparkling wine) is also produced in small quantities. A speciality since the Middle Ages is "Garnatxa", a pure sweet red wine made from Garnacha Tinta with 15.5% alcohol. This is similar to the French Banyuls across the border in the Roussillon area.
