Valentin Leflaive Blanc De Blancs Cv 17 50 Extra Brut Champagne 2017 is produced in a traditional sparkling wine region, where grapes are hand harvested at optimal ripeness to preserve freshness. Base wines are fermented at cool temperatures in stainless steel before blending.

Secondary fermentation takes place either by the classic méthode traditionnelle in bottle or the Charmat method in pressurized tanks, depending on style. Lees aging is carefully monitored to develop texture, while disgorgement and dosage decisions are made to maintain balance.

The producer emphasizes clarity, precision, and respect for tradition, ensuring a sparkling wine built on craftsmanship rather than shortcuts.
