The grapes used in the production of Dow?s Fine Ruby were a blend of traditional Portuguese varieties from the Douro Valley, such as Touriga Nacional, Touriga Franca, Tinta Barroca, Tinta Roriz and Tinto Cao. Dow?s Fine Ruby was aged in seasoned oak casks at our lodges in Vila Nova de Gaia for an average of 3 years, and bottled when ready to drink. Exuberant youthful fruit flavours make it perfect for informal drinking.
