The wine-producing area of Caldaro is located 15 km south of Bolzano and slightly above the Lake Caldaro, the warmest in the Alps. Here, the type of soil and microclimate of the differences are reflected in the presence of more than 60 vineyards from historic names as Vial, Spigel or Salt. By gently rolling hills, high until to ca. 600 meters around the lake like an horseshoe, so that most of the slopes is oriented towards the south or southeast, with direct exposure to sunlight. This fact, combined with the mild climate of the lake allows the grapes to reach full maturation and thereby develop their full aroma. In the evenings the slopes are lapped by the fresh winds from the peaks of the Mendola, 2,000 meters high: offering refreshment to rows after the heat of summer days favor the formation of fruity aroma and the preservation of the acidity in the grapes.
Crops screw around Lake Caldaro are characterized by extremely small dimensions. Most of the more than 1,000 wine growers of this area possess less than one hectare of land. For a small grower is virtually impossible to make wine and to market their own grapes. Hence the idea and the economic necessity of setting up a consortium of producers. In addition, collaboration between farmers allows to benefit from the knowledge of the cellar and the technical infrastructure, two elements necessary for the production of high quality wines. Already at the time of the founding of the Kaltern Winery, in 1906, the aim was to achieve and that is to produce high quality wines.
Currently, ca. 440 members of the Caldaro winery cultivate 300 hectares of vineyards, making part of the wineries of the most important qualities of Italy. The work in the vineyard is done almost exclusively by hand, with the application of rigid provisions for the quality control, the observance of which is controlled by the oenologist who follows and advises the farmers the whole year in their work in the country.
