Rutherford Ranch Winery is on the site of the original Round Hill Winery started in 1978 by Ernie and
Virginia Van Asperen and Charlie Abela. When the Van Asperens retired in 2000, Marko and Theo Zaninovich,
long-time shareholders with the Van Asperen family, acquired the winery. The estate vineyards were replanted
with superior vines and the winery and tasting room have undergone significant renovations.
