Campo de Borja is a Spanish Denominación de Origen (DO) for wines located in the northwest of the province of Zaragoza - Aragon. It is a transitional zone between the plains of the River Ebro and the mountains of the Sistema Ibérico. The Moncayo mountains are the dominant feature of the DO region with its micro climate which gives the wines a special character. Atlantic influences during the winter, notably a cold, dry wind from the northeast with the summer months being more Mediterranean. The vineyards are planted on a series of high plateaus at heights ranging between 350 m and 750 m above sea level.
The soils are mainly dark lime-bearing soils of average rockiness, good drainage, average level of organic matter and rich in nutrients. Closer to the Moncayo the clay and iron content increases, as does the general rockiness.
There are currently about 6,300 ha under vines which produce between 20 and 25 million kg of grapes.
Garnacha, Tempranillo, Mazuela, Cabernet Sauvignon, Merlot, Syrah as well as Macabeo and Moscatel are planted in this region.
