The Queiles Valley is traversed by a river of the same name, which crosses the Ribera from the South, originating in the North of the Moncayo mountain range. Its microclimate is highly suitable for the cultivation of vines - with, on the one hand, cold winters and extreme frosts; and on the other, hot summers, with low night temperatures by virtue of the proximity of the Iberian System. Mount Moncayo - known locally as ¨Father of the Iberia¨- has an altitude of 2,315 meters and is 15 to 20 kilometres away from the vineyards of Cascante.
The soils are the compacted results of the quaternary era. They are poor, of little depth, and lie on a stony, chalky base. Fertilized with sheep droppings every four years, they yield - depending on the grape variety - between 5 and 6,000 kilos of grapes per hectare.
Average rainfall in the valley is around 450 mm, with a medium temperature of 13º and 2700 hours of sunshine a year. Irrigated in winter, as there is a lack of rainfall during this period, with an irrigation-system of little dams and rivers developed by the Romans.
The vineyards of Guelbenzu contain 20 different plots of Tempranillo, Cabernet Sauvignon, Merlot and Grenache as bush and Guyot pruning.
