Marine Descombe represents the fifth generation of a winemaking family rooted in Beaujolais since 1905; in 2017 she acquired the Passy le Clou estate in the village of Beine, Chablis, from a retiring grower who had no heirs to pass it on to — the name recalls an old elm tree in the village where departing military conscripts would drive a nail (clou) as they left. The Petit Chablis is drawn from approximately two hectares planted on Portlandian limestone and marl, the younger continental limestone that defines the appellation and sets it apart from the Kimmeridgian chalk of the Chablis AOC proper, with vines of around thirty years farmed under rigorous agroecological principles: HVE Level 3 certified, in full organic conversion at the time of the 2022 harvest, with no herbicides, tilled soils, cover crops, natural inputs, and vitiforestry.

Vinification is carried out entirely in temperature-controlled stainless steel — low-pressure pneumatic pressing, 24 to 48 hours of static settling, complete malolactic fermentation, and 10 to 12 months of ageing on fine lees in tank — a process that preserves the purity and tension the terroir offers. The 2022 vintage delivers a fresh, citrus-driven profile of lemon, grapefruit, lime, lime blossom, and white peach, underpinned by firm, focused acidity and a classical Petit Chablis character that earned 90 points from both Decanter, where Andy Howard MW praised it as "crisp, firm and very classic in character, well put together with concentration as well as fruit ripeness," and Wine Enthusiast.
