The region has been making wines since the third century BC and the region was originally established as a Roman town, Carae, in 500BC. Monasteries controlled production through the middle ages. Some of the first regulation of the region occurred in 1694 limiting the planting of new vineyards. Cariñena was the first Denominacion of Origin in Aragon, established in 1932, and has given its name to the grape, Cariñena, also known as Mazuelo (in other parts of Spain) and Carignan (in France).
Climate: The climate is a harsh Continental climate with wide swings between daytime and nighttime temperatures. The high temperatures range around 100 in the summer and the lows in winter around 45. The region is also subject to high winds from the north that help keep humidity low.
Soil: Predominately reddish-brown limestone over rocky subsoils. There are also some regions of alluvial and slate soils.
Grape Varities: Red Garnacha (55% of existing vineyards) and Viura (White) are the major planted varieties. Recently Tempranillo has seen increasing plantings as producers in the region continue to increase the production of aged wines. Typically vines are espalier trained without wires and planted in a rectangular pattern. Vine density ranges from 1,500 to 3,000 vines per hectare.
