Vineyards of the Campo de Borja Designation of Origin Nature · Ainzón, Campo de Borja, Zaragoza Image of Ainzón, not of the place itself. The vineyards of the Campo de Borja Denominación de Origen stretch out at the foot of the Moncayo, in the northwest of the province of Zaragoza, and bring together sixteen municipalities, including Ainzón, over an area of more than 6,000 hectares. The denomination, recognised since 1977, sits on limestone soils rich in nutrients, at altitudes between 350 and 700 metres, under a continental climate with scarce rainfall. Garnacha, the area's historic variety, grows alongside tempranillo, cariñena, cabernet sauvignon, syrah and merlot among the reds, and macabeo, chardonnay and muscatel among the whites. Ainzón is home to Bodegas Ainzón, one of the denomination's certified wineries. Photo: Iggy1975 (CC0) What to see and do in Ainzón
