Among the vineyards of Mazzon is Brunnenhof, a large winery, visibly devoted to the preservation of traditions but also to the promotion of innovations. Since 1987 it has been owned by the Rottensteiner family.Pinot Noir is the prince of Brunnenhof, and could not be otherwise, since we are on the rich sandy-clay soils of Mazzon. Pinot Noir has been around for over a century now. It is said that it was introduced by Ludwig von Barth of Barthenau. At one time even in the Brunnenhof estate - as everywhere in South Tyrol - the vine was cultivated in pergola; by now all the plants present on the 2.56 hectares of land of the estate are trained in espaliers (Guyot). From 6 to 8 thousand plants per hectare. The traditional pergolas are reduced to one of the 2.5 hectares of land leased from the castle estate. Pinot Nero is a delicate vine. Therefore, the utmost attention is paid to work in the vineyards, from winter pruning to the autumn harvest. The use of mineral fertilizers, herbicides, insecticides and chemical products to fight botrytis is avoided and substances that act as bait are used to confuse the vine moth, using mainly copper and sulfur to counteract the fungus infestations.
