In order to achieve its objectives, from the very beginning it has taken a very different path from what was usual for the production of Vinho Verde: refusing, for example, to introduce CO2 into wine, which was then the style of Vinho Verde or to accept the settlement defined for the Amarante sub-region, without previously studying the behavior of the grape varieties in their terroir. Thus, he has created and has been in production since 1996 the wine Quinta de Sanjoanne Terroir Mineral, from the grape varieties Loureiro and Avesso, with a crystalline and deep profile, that allows it to evolve in bottle and improve with age. In this way, it also contradicted the common sense that Vinho Verde could only be drunk young and that it had no capacity for evolution, showing that by working for quality, this wine can grow old like any other wine of character. With the increasing of its terroirs, the behavior of the grape varieties and the numerous trials in the vineyard and the wine cellar, it was readjusted to the vineyards for the production of the various wines of Quinta de Sanjoanne, which in the meantime was creating and developing. Currently, the vineyards of Quinta de Sanjoanne have the following varieties: Arinto, Alvarinho, Avesso, Trajadura, Malvasia Fina and Loureiro.
