Grown exclusively in the Vigna Kastelaz site above Tramin, where the variety originated, at an altitude of 350 meters above sea level. Vines are planted on a very steep slope with narrow terraces, trained on the guyot trellising system at a density of 7.500 plants per hectare. The soils are a mixture of chalk and clay and the vineyard has been a classic Gewürztraminer site for generations.
Very carefully selected, fully ripe grapes get selected, picked in two harvests. Before pressing, the crushed berries are cold macerated for 6 hours, after which the juice is clarified by refrigeration and natural sedimentation. Fermentation is activated using selected yeasts and the temperature is controlled at 18°C. The young wine remains on its lees for several months. It follows a bottle aging for four years in an old silver mine in the Ridnaun Valley (Alto Adige) at 2.000m a.s.l. in absolute darkness and complete isolation three kilometres inside the cliffs. The steady temperature of 7 degrees Celsius and 95 per cent humidity, together with the extremely low air pressure, positively influence the maturation process of this wine, giving it long youth.
