O-X is a sparkling rosé blend of Glera and Pinot Nero, sourced from the hills and mountains. The Pinot Nero comes from the Belluno area, with sedimentary and marl soils, and the vines are 15 years old. The Glera undergoes direct pressing, while the Pinot Noir undergoes pink vinification. After spontaneous fermentation, the wine ages for 3-4 months in steel and is bottled with must from dried grapes.
