Duorum Reserva Old Vines
Wine Description
This wine is an old-vine field blend up to 100 years old consisting mainly of Touriga Nacional and Touriga Franca with small quantities of Tinta Roriz and Sousão. The grapes are sourced from the Cima Corgo and Douro Superior sub-regions, which offer exceptional terroir and a range of elevations and vineyard 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.
