Champagne Coessens Largillier Les Sens Boises Blanc de Noirs Extra Brut

When Jérôme Coessens established his label in 2006, he made a deliberate choice that inverts Champagne's foundational logic: no blending across sites, no reserve wines, no Chardonnay — every bottle a single vintage from a single 3.36-hectare monopole in Ville-sur-Arce. Les Sens Boisés goes further still, drawing exclusively from the Mineral sub-parcel of lieu-dit Largillier, the plot whose Kimmeridgian Marl No. 2 soil — excavated in 2011 and confirmed geologically identical to Chablis Grand Cru — delivers the estate's most pronounced chalk-and-clay tension.

The transgression here is total: where virtually every Champagne house ferments in stainless steel, the entire vinification of Les Sens Boisés — alcoholic fermentation, malolactic conversion, and stabilisation — takes place in 5–6-year-old oak barrels sourced directly from Benoît Droin in Chablis. Old wood adds textural weight without imparting primary oak flavour, amplifying the clay-driven body the Kimmeridgian soil already provides. The wine then ages ~26 months sur lattes before disgorgement at ~6 g/L dosage — Extra Brut territory that keeps the Mineral plot's chalk-driven length unobscured.

The result is a Blanc de Noirs that operates outside both the Champagne and Burgundy playbooks simultaneously: sparkling in form, yet vinified with the barrel discipline of a white Burgundy, from a monopole that has no peer in the Aube.
