Touriga Franca/Touriga Nacional/Tinta Roriz plus mixed-variety old vines. From exclusively Class A parcels (Serra Douro and Serra de Baixho) totaling seven and one-half hectares on poor schist soils—the vines are fifty years or older. The fruit is hand-harvested, partly destemmed and fermented exclusively in lagar; fermentation is stopped with seventy-seven-degree wine brandy. The wine is aged for two years in a variety of tonel and balseiro, which are tall wooden tanks from 3,000-60,000 liters with thick staves that slow down oxidation. It finished at a modest nineteen and one-haf percent alcohol and seventy-two grams per liter of residual sugar and was bottled (and numbered) without fining or filtering in July 2015.
