Josko Gravner of Gravner Wines ferments deeply — he ferments his wine in large amphora, clay vessels that he buries outdoors. Gravner, who helped pioneer the wave of orange wines, runs a family cellar in northeastern Italy. He became “disillusioned with modern enology’s techniques” of conventional wines — like steel tanks in the cellar and chemical fertilizers in the vineyards. Gravner Wines is now an organic farm and very low tech, using a 1950s-era hydraulic basket press and ancient fermenting techniques. The wine is not only buried, it’s made using whole-cluster fermentation with the stems. Gravner finds whole-cluster fermentation in amphorae keeps the grape skins naturally submerged while still aerating the wine without manual punch downs.
