The Callejo family has been growing grapes for 4 generations, all the while maintaining traditional practices. The family owns 60 Has (150 acres) in Sotillo de la Ribera, the very heart of Ribera del Duero. The estate is planted with some of the best vines in the region, ranging in age from 25 to 65 years. The vines are also among the highest planted in the region, at almost 2800 feet, and are organically and dry-farmed (don't receive any artificial irrigation). No pesticides or fertilizers are used on the estate.
Jose Felix, the winemaker, does a strict green pruning and selection. An average of only 8 bunches are allowed to develop per plant. The maximum yield obtained is 4000 kg/Ha.
Callejo uses only grapes from its estate. The grapes are carefully selected and handpicked into small cases of 30 pounds. The crates are taken directly to the winery, where they go through two sorting tables, the second one selecting individual grapes to ensure only the best fruit ends up in the wine.
