Jean-Marc’s only blanc de blancs, from five mature plantations in the Marne Valley, the Côte des Blancs, and Pierry. Approximately half the wine is raised in steel with natural malolactic fermentation, and half is raised in older barrels without ML. 

The cold stabilization is completed naturally, and there is neither fining nor filtration. In July, after a long, gentle aging following the harvest, the wine is blended with 20-30% Chardonnay from a solera (unlike the perpetual cuvée, the solera is replenished strictly with the new harvest) and goes into bottle to rest on its lees until it is disgorged. The lot number on the back is the base vintage. Annual production averages 325 cases.
