Domaine Diochon produces Gamay from Moulin-à-Vent, the northernmost and most structured cru of Beaujolais. The region's granite and schist soils yield wines of mineral precision and aging potential—a departure from the lighter, fruit-forward profile associated with the broader appellation. The winery's Moulin-à-Vent expresses the classic character of the terroir, while the Cuvée Vieilles Vignes, drawn from older vines, deepens that mineral core with additional complexity. Both wines have been assessed by Wine Spectator, Wine Advocate, and Wine Enthusiast. Moulin-à-Vent demands time in glass or cellar to reveal its structure; the Vieilles Vignes particularly rewards patience, unfolding layers beneath its initial tannin framework.
