In the 1980s, discussions with wine-growers from all over the world such as Robert Mondavi, the famous pioneer of wine-growing in America, and various chateau owners in the Bordeaux region encouraged Alois Lageder to introduce Cabernet Sauvignon and Petit Verdot in the form of wire trellis system as a replacement for the traditional Schiava. The result, in 1986, was Alto Adige’s first major vineyard with densely planted Guyot-trained vines – a fact that caused much discussion. This site has traditionally been called "Herz" (German for heart or Cor in Latin) and has given the wine its name.

For our Römigberg Schiava, the vines are still trained using the traditional pergola trellis system. In view of climate change and the increasing alcohol content in the wines, we believe that the pergola offers better protection for the thin-skinned berries and underscores the freshness and lightness of the wine, which is a product of the unique diversity of this site.

The northwest shore of Lake Caldaro lies at the foot of a spectacular steep slope that is one of the best sites in the region. The interaction of different soils and climatic conditions makes this 8-hectare monopole a unique wine-growing playground. It comes very close to our ideal of a farm as a self-contained living organism, with great importance attached to coexistence for human beings, animals and plants. In our case, cows, donkeys and sheep graze between the vines, olive and loquat trees. Bees, chickens, geese and peacocks are also denizens of this very special habitat.
