Quinta do Vesuvio, Symington Family Estates is a recognized crown jewel of Portugal's Douro Valley, Quinta do Vesuvio's history spans back to the 16th century. Its 1000 acre estate lies in the dry, austere Upper Douro Valley and stands alone, both in terms of remoteness and sheer grandeur. Since acquiring the winery in 1989, the Symingtons have added several technological innovations - most notably a cooling system built within its stone lagares to better control fermentation. Vesuvio makes only a very small quantity of Single Quinta Vintage Port each year.
