Everyone should drink more Portuguese wine... Made from grapes coming from old vines at Quinta do Crasto averaging around 70 years of age(!), Quinta do Crasto Reserva Old Vines is an authentic blend of the best that the Douro has to offer. It has built a solid national and international reputation. The low yield of these old vines, together with the 18 months that the wine ages in French and American oak barrels in the temperature-controlled Barrel Cellar, makes Quinta do Crasto Reserva Old Vines a complex and concentrated wine.
