Hesperian Wines, founded by French-trained winemaker Philippe Langner, focuses on limited-production Cabernet Sauvignon from select vineyards in Napa Valley. The name "Hesperian" refers to the western lands of Greek mythology, reflecting the western position of California in the United States.

The winery is known for its meticulous vineyard selection and hands-on approach to winemaking, with an emphasis on minimal intervention to express the unique terroir of each vineyard site. Philippe personally oversees every aspect of production, from vineyard management to bottling, resulting in wines that are elegant, balanced, and built for aging.

Hesperian's flagship wines are crafted primarily from hillside and mountain vineyards in the Atlas Peak and Coombsville regions of Napa Valley.
