Jean-Marc’s only blanc de blancs, from five mature plantations in the Marne Valley, the Côte des Blancs, and Pierry. Half the wine is raised in steel with natural malolactic fermentation, and half is raised in older barrels without malolactic. The cold stabilization is completed naturally, and there is neither fining nor filtration. The wine is aged on its lees for a minimum of 36 months.
