Castilla-León, in the center of old Catholic Spain, lies in the center of the country, and stretches to the north to Burgos province. The climate is rich in contrast: icy cold winters, and very hot summers. The land is parched - there is only very little rain. These factor make viniculture difficult, and production has gone down in some provinces. In spite of the hostile weather there are plenty of quality wines like e.g. from Toro, Ribera del Duero, Rueda, and the light wines from Bierzo und Cigalés. The white wines from Valladolid is also famous (from the Palomino vine, that is also used for the Jerez wines)
The most important vine is the dark Vino Tinto, a type of Tempranillo and the Prieto Picudo (for the rosé), and the white Verdejo.
Though guild cellars are very successful here, there are also private vintners, that make lots of wine for local consumption.
