On its home ground, Rioja wine has a rich supporting cast: the region’s raw materials include pasture-raised lamb, wild game, suckling pig, asparagus, wild mushrooms, glistening sweet peppers and eggplant. Vegetable farming thrives along the banks of the Ebro River, filling local markets with fresh-picked produce. Every year, the village of Logroño holds a Fiesta de la Verdura, or produce festival, drawing a throng that comes to celebrate the local harvest. Even the region’s best chefs, who cook for an international audience, love to showcase what comes from Rioja’s backyard. For more information about this series, please visit www.ciaprochef.com/rioja.
