Domaine Pierre Gonon produces wines in Ardèche, a region in southeastern France known for its diverse terroirs and distinctive expressions of classic varieties. The domaine focuses on Syrah and Chasselas, grapes that thrive in the region's continental climate and varied soils. Vielles Vignes Saint-Joseph, a Syrah-based wine, represents the domaine's work with older vines, while Les Iles Feray offers another expression of the same variety. The Chasselas, a white wine from an underappreciated varietal, rounds out the portfolio. These wines have been evaluated by major critics including Wine Spectator, Wine Advocate, Wine Enthusiast, and Decanter, reflecting their place within serious wine discourse. Ardèche's position outside the formal Appellation d'Origine Contrôlée system allows producers here greater flexibility in winemaking choices, a characteristic that shapes the character of wines from this region.
