Previously, this cuv??e had gone under the name of ???Blanc de Blancs??? since the beginning of the 20th century. It is made exclusively from our Chardonnays grown on the C??te des Blancs: Vertus, Oger, Avize, Cramant, which form a line close to the 4th meridian. ???Longitude??? is also an allusion to the length and the very pure, frank and mineral style of these great terroirs, where the chalk is very close to the surface.
The natural alcoholic fermentation (natural yeast) and the malolactic fermentation begin spontaneously in our casks, our wooden vats and our stainless-steel tanks. The wines are left on their natural lees for nearly a year and undergo gentle b??tonnages, but no filtering or fining. The blending and the bottling are carried out in July. The bottles are then taken down into the coolness of our cellars, where the second fermentation and the maturation 'on laths' quietly take place over a period of more than 2 years. Each bottle is disgorged manually 6 months before being marketed. The dosage is 4 grams per litre (extra-brut!).
