Like the Latitude, this is 100% Côte des Blancs Chardonnay (the vineyards are in Cramant, Avize, Oger, and Vertus), 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 of wine resulting from the very chalky soils of these sites i.e., a more linear, mineral wine. While Larmandiers Latitude is expansive across the palate, the Longitude is all about minerality, line and raciness. William Kelly has called this wine one of the finest non-vintage bottlings to be found in Champagne and, while the are no reviews available for the 2019 base, the high ratio of reserve wines (40%) and the strength of this low-yielding vintage should leave you will little doubt as the quality on offer.
