Ligne de Mire is a Blanc de Blancs made entirely from Chardonnay grown on the certified organic plots in Vandières. Chardonnay is less common in the Marne valley than in the Côte des Blancs, and Bastien's version is leaner and more mineral than most. The grapes are pressed and fermented in thermoregulated stainless steel tanks. Malolactic fermentation is carried out. No oak is used. The wine was bottled in spring 2023. Dosage: Brut, 4 g/L.
