Old Vines Quinta do Vallado, built in 1716, is one of the oldest and most famous Quintas in the Douro Valley. It comes from an old vineyard of about 100 years old, with a mixture of 34 grape varieties. The Vinha da Coroa is located at the highest point of Quinta do Vallado, as a crown on the vineyards. After a fermentation of 14 days with very little extraction, the wine aged for approximately 18 months in French oak barrels of 2nd year.
