Matsu is the essence of a sustainable viticulture project. From among the extraordinary quality vineyards that abound in the D.O. Toro, Zamora, in Spain, the Technical Director of Matsu, Raúl Acha, selects authentic centenary jewels with which it is possible to obtain an exceptional grape. They are vineyards between 80 and 100 years old with very low production per vine, cultivated according to the tradition of not interfering with the logical processes that nature dictates. This age-old philosophy, together with privileged climatic conditions, makes it possible for the viticulture carried out here to be practically artisanal.
