Les Frères Perroud works Gamay in Brouilly, one of Beaujolais's ten crus. The region's granite and schist soils yield wines of bright acidity and mineral tension—hallmarks of northern Beaujolais. The winery's Améthyste Brouilly, made from Gamay Noir, and its Vieilles Vignes Brouilly demonstrate the variety's range across vineyard sites. Both wines have drawn assessment from Wine Advocate and Wine Enthusiast. Gamay's natural elegance—its low tannin, high-toned fruit, and food-friendly profile—defines the Brouilly cru, where old-vine parcels often yield deeper complexity and structure than younger plantings. Les Frères Perroud's focus on this single appellation and grape reflects the traditional Beaujolais model of terroir-driven expression within a narrow geographic frame.
