A fizzy and delicious natural sparkling wine from Portugal's Douro Valley. Approachable & refreshing. From +80 year old vines planted on 2 hectares of schist and granite. The more than 25 red and white varietals are hand harvested separately in September and undergo vineyard sorting. The whole clusters macerate for three days, followed by spontaneous fermentation with wild yeasts lasting roughly three weeks in large granite lagars (1000L). The wine spends six months on lees with stirring once every two weeks only at the beginning of aging. Aged for six months in 2-3 year old chestnut oak (225L)(5%) and the rest in cement. Not fined or filtere!
