Grand Nicolet produces wines from Rasteau, a sun-drenched appellation in the Southern Rhône known for structured reds built on Grenache and Syrah. The winery's flagship, Les Esqueyrons Rasteau, blends Grenache and Shiraz into a wine that has drawn attention from Wine Enthusiast, Wine Spectator, and Wine Advocate. Vieilles Vignes Rasteau, also Grenache and Shiraz-based, follows a similar path of dark fruit and peppery spice characteristic of the region. Terre Des Bertrand Rasteau adds Carignan to the Syrah and Grenache base, introducing additional textural complexity. These wines reflect the Southern Rhône's warm terroir and the traditional Mediterranean blend structure that defines the area.
