100% Espadeiro sourced from Rui Paiva, nephew of Biodynamic producer Fernando Paiva. Rui has 4 hectares of mostly 20-year-old vines in the Vinho Verde area of Felgueiras. The harvest was done by three generations, Rui, his 80-year-old father and his nephew. Grapes were placed on 20kg boxes and taken to Bojo do Luar cellar, 7km away. Upon arrival, the grapes were destemmed and moved into "ta/has" (100-year-old, 1.100L amphoras) and stumped by foot. To each amphora, 1kg of ground chestnut flowers was added and immediately mixed into the mass. The fermentation started spontaneously after four days and continued slowly for one month. The wine was kept macerating in ta/has, from the second week of October until mid­January, when it was moved to steel tanks and bottled in March, unfiltered with S02 added at bottling (30ppm).
