Gravner is a family-owned winery from the village of Oslavia, on the border between Italy and Slovenia, in the Friuli-Venezia Giulia region, recognized for its radical winemaking philosophy and pioneering role in the world of orange wines. Joško Gravner took over the winery in 1973, but it was in the mid-1990s that he made a decisive shift away from modern technology and returned to natural, traditional methods.
