Les Pierrières 48 months (2016)

40-year-old Chardonnay have southern exposure and are planted on chalky soils that also feature chunks and pockets of a rare black flint or silex noir unique to Coteaux du Petit Morin. Pierrières was Olivier Collin's first bottling, and only bottling, in the 2004 vintage. The fruit is hand-harvested, the clusters destemmed and the grapes gently pressed; the juice is fermented spontaneously and slowly (up to six months) with natural yeasts in mainly-used Burgundy barrels. Reserve wines are held in foudres and tonneaux. The wine is based on 2017. It's bottled without fining or filtering and aged for 36 months on lees.
