The rocky and chalky soils of Montecastro are at one of the highest points in the D.O. of Ribera del Duero. The potential of this site is what lured the Del Rio family to purchase the property in 2012. While previous wines made here have a rustic charm, decades of experience in running Hacienda Monasterio have taught the Del Rios how to tame the native Tinto Fino into something more elegant and precise. By including some stems in the fermentation and by reducing the time in barrel and the percentages of new wood, Montecastro is evolving into one of the best values in Ribera del Duero.
