This is 2018 base with between 35 and 40% reserve wines going back to 2004. Like the Latitude, this is 100% Côte des Blancs Chardonnay, yet the vineyards from which it was drawn have thinner topsoils and so the vine roots plunge straight into the chalky bedrock. The name here refers to the vertical nature of the geographic locations of the vineyards as well as the style that results from the very chalky soils of these sites—a more linear, mineral wine. The vineyards are located in Cramant, Avize, Oger, and Vertus (north of the village).
