Marine Descombe represents the fifth generation of a Beaujolais winemaking family established in 1905, and in 2017 she purchased the Passy le Clou estate in Beine, working 21 individually vinified parcels within the Chablis AOC. The soils are classic Kimmeridgian marl — stony, clay-limestone rich in ancient oyster fossils — the same geological foundation that defines authentic Chablis terroir and sets it apart from the younger Portlandian soils found in Petit Chablis. Farming is agroecological throughout: HVE Level 3 certified and in full organic conversion during the 2022 harvest, with no herbicides, tilled soils, and cover crops maintained across the estate.

Vinification takes place entirely in stainless steel, beginning with low-pressure pneumatic pressing and 24 to 48 hours of static settling, followed by complete malolactic fermentation to round the wine's naturally firm acidity. The 2022 then aged on fine lees in tank for 15 to 18 months — a notably longer elevage than for the Petit Chablis and a key differentiator between the two cuvées. Critics responded well: Decanter awarded 91 points, describing it as "very appealing, lots of drive and focus — fine combination of ripe fruit, zesty acidity, mineral edge to finish," while Wine Enthusiast followed with 90 points.
