Bodega Vitivinicola del Ribeiro Ribeiro DO (Denominación de Origen) is a wine region within the Galiciaautonomous region of Spain. It is located between the famous Rias Baixasto the west and Ribeira Sacra to the east. The Ribeiro DO title was official established in 1957, and is governed by the local Consejo Regulador(wine-regulating authority). Winemaking has long been important to Ribeiro – the Romans introduced the tradition in ancient times and Cistercian monks acted as custodians throughout the Middle Ages. Since early times, wine has been the region’s primary source of income and employment. Four rivers – the Barbatino, Avia, Arnoia and Miño – converge here, and vineyards line the river valley floors and terraces cling to the steep hillsides. The maritime influence of the Atlantic Ocean is evident in Ribeiro, with relatively high rainfall and humidity, although its inland location shelters it from the brunt of Atlantic storms. It is also.
