Bonserine produces wines from Côte-Rôtie, the steep-terraced appellation of France's Northern Rhône where Syrah reaches its most elegant expression. The winery's flagship Côte-Rôtie 'La Viallière' and La Garde Côte-Rôtie showcase the region's signature dark fruit intensity and mineral structure, built on Syrah's natural affinity for these granite and schist slopes. Both wines have drawn assessment from major critics including Decanter, Wine Spectator, Wine Advocate, and Wine Enthusiast. Beyond red, Bonserine also works with Viognier in nearby Condrieu, the white appellation where this floral, stone-fruit variety thrives. The winery's range reflects the Northern Rhône's dual character: powerful, age-worthy reds and aromatic whites from a region defined by its unforgiving terrain and exacting standards.
