Marie-Pierre Chevassu-Fassenet's Crémant du Jura is a sparkling wine from the Jura region of France, specifically known for its white Crémant made from 100% Chardonnay. The wine is produced at the Les Granges-Bernard farm, where Marie-Pierre Chevassu-Fassenet took over the wine estate in 2008. The wine is made using traditional methods, with a focus on organic and low-intervention practices. The grapes are hand-harvested, and fermentation is done using indigenous yeasts.
