Our district is the first viticultural area in the United States to be approved based on the distinctiveness of its soils. There is a great diversity of soils within the Stags Leap District, from the rocky, coarse, well-drained soils below the palisades to alluvial clay found closer to the Napa River. Soils on the eastern elevation are the result of volcanic eruptions that took place millions of years ago, as well as the slow erosion of the arid Vaca Mountains. These gravely soils, are coarser and retain less water than most, resulting in low-vigor vines that provide Regusci Winery with fruit of great intensity and flavor.
