Duorum Reserva Old Vines
Wine Description
A field blend consisting mainly of Touriga Nacional and Touriga Franca, with small quantities of Tinta Roriz and Sousão blended in. These grapes are sourced from two different sub-regions, the Cima Corgo and High Douro, two exceptional terroirs with different elevations and characteristics. The grapes are harvested from September to October and undergo a cold maceration in lagares for two to three days. The wine is aged approximately 12 to 18 months in French oak barrels.
