Montirius produces wines from the Southern Rhône, where Grenache, Mourvèdre, and Syrah thrive in the region's warm, sun-exposed terroirs. The winery's portfolio centers on two appellations: Gigondas and Vacqueyras, both known for structured, age-worthy reds built on these Mediterranean varieties. La Tour Gigondas blends Grenache, Mourvèdre, and Syrah into a wine that has earned recognition from Wine Advocate, Decanter, Wine Enthusiast, Wine Spectator, and Falstaff. Confidentiel Gigondas, a Mourvèdre and Grenache blend, similarly draws critical attention. Le Clos Vacqueyras rounds out the core range, pairing Syrah and Grenache in the lighter-bodied Vacqueyras appellation. These wines reflect the Southern Rhône's signature style: ripe fruit, herbal undertones, and the tannin structure that defines the region's best expressions.
