The Felix Callejo family has been growing grapes for 4 generations in Sotillo de la Ribera with little changes. Grapes are still carefully tended, selected and handpicked. The family owns 60 hectares in Sotillo de la Ribera, the very heart of Ribera del Duero. The age of the vines range from 25 to 50 years. Yields are limited naturally by the hard continental climate and a poor soil of low fertility. On top of that Jose Felix, the winemaker does a strict green prunning and selection, and average of only 8 bunches are allowed per plant. Felix Callejo uses only grapes from own estate vineyards. The grapes are carefully selected and handpicked into small cases of 30 pounds.
