Olivier Dumaine produces wines from Crozes-Hermitage, the largest appellation in the Northern Rhône. The winery's La Croix du Verre line showcases the region's signature expressions: a white built on Marsanne's textural depth, and a red anchored in Syrah's dark fruit and peppery structure. Both have been assessed by Wine Spectator, Wine Enthusiast, Wine Advocate, and Decanter. A core Crozes-Hermitage red rounds out the portfolio, offering the appellation's characteristic balance of ripe fruit and mineral tension. Northern Rhône whites tend toward honeyed complexity and subtle oak; the reds combine power with elegance, shaped by steep granite slopes and continental climate. Dumaine's offerings reflect this terroir-driven tradition.
