The winery is located in the municipality of Bolzano (Bolzano) in the Italian wine-growing area South-Tirol
(Region Trentino-Alto Adige
). The traditional family is one of the oldest in South Tyrol and has been associated with viticulture for many generations. This is also evidenced by the surname derived from the porphyry, the red rock of the mountains around Bolzano. The current operation was founded in 1956 by Hans Rottensteiner and is now run jointly by son Toni and grandson Hannes.
