La Haute Lemblé is a Chardonnay wine and vineyard from Cédric Bouchard's Roses de Jeanne wine collection, and the 2021 vintage is a single-vineyard, single-vintage Blanc de Blancs wine produced in the Côtes de Bar in southern Champagne. Since it was bottled without dosage, no sugar was added during the disgorgement process. The alcohol content is 12.5%, and the bottles were disgorged in June 2025.
That year was a harsh one. The vines began to leaf out in late March, but frosts occurred for 12 days, from the 6th of April to the 3rd of May, with the coldest nighttime temperature in Celles-sur-Ource dropping to -5.8°C. Subsequent hailstorms damaged 500 hectares across the region, with half of that area suffering a complete loss of yield. A cold, wet May and then downy mildew from June onwards did the rest. In one section of the Côtes de Bar, the Barséquanais, frost alone caused the loss of approximately 63% of the expected yield, which was the most severe figure recorded in Champagne.
Harvesting began on the 6th of September and continued through the 27th of September, with the entire process carried out entirely by hand. Since the degree of ripeness varied drastically from plot to plot, selection became even more important than quantity for this vintage. Very little wine was produced here.
