Saumur-Champigny built on limestone-rich clays, and Domaine des Closiers reads that site with a deliberately light hand: hand-harvested fruit, spontaneous fermentation on indigenous yeasts, a cold soak before things get going, and macerations that can run past a month with no punchdowns. Just a brief pumpover every day or two. That's a long time on skins for so little force, and it shows in the shape of the wine: Cabernet Franc with real mid-palate presence and fine-grained tannin rather than muscle, minerality running underneath. Patience instead of pressure. You can taste the difference.
