Touriga Franca/Touriga Nacional/Tinta Roriz plus mixed-variety old vines. From exclusively Class A parcels (Serra Douro and Serra de Baixho) totaling 7.5 hectares on poor schist soils—the vines are 50 years or older. The fruit is hand-harvested, partly destemmed and fermented exclusively in lagar; fermentation is stopped with 77%-degree wine brandy. The wine is aged for 2 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 19.5% and 72 grams/liter of residual sugar and was bottled (and numbered) without fining or filtering in July 2015.
