Harbison produces Cabernet Sauvignon from Oakville, the Napa Valley appellation renowned for structured, age-worthy reds with dark fruit intensity and refined tannins. The winery's portfolio centers on three expressions: Horseshoe, Pony Express, and The Trail—each a Cabernet that has earned recognition from Decanter, Wine Enthusiast, and Wine Advocate. Oakville's gravelly benchland soils and moderate climate create conditions for Cabernet to achieve both power and elegance, characteristics evident across Harbison's lineup. The winery's focus on a single varietal allows for deep exploration of terroir expression and vintage nuance within the appellation's distinctive growing conditions.
