Made from a blend of 85% Nebbiolo grapes and 15% Vespolina grapes, sourced from 30 to 50-year-old vineyards with mineral-rich soils of volcanic porphyric gravel. The grapes undergo a long fermentation process with their skins in open steel and wood casks. The malolactic fermentation occurs spontaneously in wooden barrels following the harvest during springtime. Le Piane Boca D.O.C 2017 was aged four years, bottled without filtration or fining in 2021, and rested for six additional months before being made available for sale.
