Jaboulet-Isnard produces wines from the Rhone Valley, where Syrah, Grenache, and Mourvèdre thrive in continental and Mediterranean climates. The winery's Hermitage, built on Syrah, represents the northern Rhone's signature expression—a wine of structure and depth that has drawn attention from Wine Spectator, Wine Advocate, Wine Enthusiast, and Decanter. The Côtes du Ventoux, a blend of Syrah, Mourvèdre, and Grenache, demonstrates the winery's range across the broader Rhone region, where these varieties achieve ripe, layered character at a more accessible tier. Both wines reflect the terroir and varietal character of their respective appellations.
