Matsu El Viejo is part of a wine range, where the age of the vine-grower on the label describes the nature of the wine, ripening, development and also the age of the vines. El Viejo comes from the Toro wine region in the Duero river valley in north-western Spain. The region’s hot and dry climate produces full-bodied and earthy wines. The best bunches have been selected from vines over 100 years old. The wine is macerated and has been in cement tanks for 3 weeks. Malolactic fermentation has taken place in French oak casks. The unfiltered wine has matured for at least 16 months in new French oak casks.
