Terra Alto is a Denominación de Origen for wines in the Catalonia region of Spain. Established in 1972, the area has a long history of winemaking, although until more recent years, the wines produced here were predominantly consumed by locals. Today, the number of growers and producers here continues to increase, and many of the wineries are built in a distinctive modernist style. Climatically, the region experiences significant variation between seasons, with long hot summers replaced by cold winters and temperatures plummeting below zero. Red, white and rosé wines are permitted under the label, from a range of grapes including Garnacha (Garnatxa), Cabernet Sauvignon, Merlot, Macabeo, Sauvignon Blanc and Pedro Ximénez.
