Gravner Company where the owner Josko Gravner is considered the master of orange wines, the one who has revived and enhanced the ancestral use of terracotta amphorae and very long macerations on the skins. The winery is located in the small hamlet of Oslavia, here Josko works in symbiosis with nature, guiding it, caring for it and also serving it, always respecting its rhythms and spontaneous cycles. The Gravner estate extends over 32 hectares of land, of which just over 15 are dedicated to vines, surrounded by woods, meadows and ponds populated by numerous species of animals. In this environment of remarkable biodiversity, Josko follows the lunar phases with particular attention, consulting Maria Thun's calendar in order to identify the most suitable periods for carrying out agronomic operations such as pruning, sowing and harvesting, where fermentations take place exclusively in buried Georgian amphorae thanks to the presence of only indigenous yeasts, accompanied by a very prolonged contact between the must and the skins that reaches up to several months for the Ribolla. This is followed by a few years of aging in large Slavonian oak barrels and a further long period of refinement in the bottle before the final release.
