Dresser Winery sources its Primitivo and Grenache fruit from Two Hills vineyard which is nestled onto South and South West facing slopes of the Huerhuero Hills along the Northern border of El Pomar District. This is an uplifted area rising 1,258 feet above sea level along the La Panza–Huerhuero Fault. The hillsides are underlain by granitic rocks, sandstones and calcareous shale fragments with lime deposits and eroded sediment overlaying the surface. The soil series is Linne-Calodo and is primarily alkaline. The soil texture is clay and sandy loams of shallow to moderate rooting depths with modest nutrient levels and low to moderate water holding capacity creating a low to moderate vigor vineyard site that can produce intensely flavored and aromatic fruit. The slopes are significant ranging from 11 to 28 percent.
