60% Pinot Noir, 40% Chardonnay. As with Boulard’s other non-vintage cuvées, the Grand Montagne consists generally of three vintages with reserve wines making up about 30% of the blend. In the current bottling, the base is 2012 with reserve from 2010 and 2011. The fruit comes from the grand cru village of Mailly-Champagne in the Grand Montagne zone of the Montagne de Reims. The Mailly vineyards vary quite a bit in exposure and soil particulars but generally are northern-oriented and favorable for Pinot Noir, which makes up 75% of its plantings, with the rest in Chardonnay. Boulard rents and organically farms a parcel with vines averaging 30 years old on clay-limestone soils.
As for all Boulard wines, the grapes are harvested by hand and pressed gently; only first-press juice (la cuvée) is used. It is fermented spontaneously in oak, a combination of 5-hectoliter half-hogsheads and well-used, neutral Burgundian and Champagne barrels. The wine undergoes malolactic fermentation and remains on its lees with regular stirring (bâtonnage) but only on fruit and flower days per the lunar calendar; it is bottled without fining and with a minimal amount of sulfur. The wine was disgorged by hand in March 2016 and finished with a small 5 gram/liter dosage.
