A Grand Cru vintage extra‑brut cuvée sourced from selected Grand Cru terroirs. The wine is a blend of Chardonnay (60%) and Pinot Noir (40%), with base wines vinified in oak and regular bâtonnage to build structure and a velvety texture. On the palate it displays saline, mineral notes and a savory persistence evoking the 'umami' character for which the cuvée is named.
