The wine is made with grapes of the Prieto Picudo variety, native to the province of León. They come from a single vineyard of advanced age located in Pajares de los Oteros on very sandy soils, planted in goblet system in 1930. It differs from the rest of the varieties in having practically the entire vine buried and the branches spread out on the ground, which forces us to carry out pruning and a very demanding farming in order to maintain the health of the fruit until it is harvested.
