His background includes winemaking experience in Napa and Sonoma, work associated with Etude Wines, Chateau St. Jean, Sledgehammer, and Run Riot, and international experience with Wolf Blass in Australia’s Barossa Valley.

Rutherford Ranch Background

Rutherford Ranch is located on Napa Valley’s Silverado Trail within the Rutherford District. The Rutherford AVA is particularly associated with Cabernet Sauvignon and is known for its historic vineyards, warm daytime conditions, cool evenings, and distinctive terroir.
The property was originally the site of Round Hill Winery, established in 1978 by Ernie and Virginia Van Asperen and Charlie Abela. When the Van Asperens retired in 2000, Marko and Theo Zaninovich acquired the operation.
Following the acquisition, the estate vineyards were replanted, and the winery and tasting room underwent substantial renovation. The estate’s approximately century-old olive grove was retained as part of the property’s agricultural and historical character.
Rutherford Ranch describes itself as family-owned and family-managed, with three generations involved in the winery business. Today, Rutherford Ranch combines premium Napa Valley winemaking with direct-to-consumer wine sales, wine-club membership, educational tastings, vineyard experiences, and estate hospitality.

The hosting of these assets by Rutherford Wine Company reflects the operating relationship between the organizations and should not be interpreted as meaning that all Rutherford Wine Company trade programs or portfolio activities are Rutherford Ranch offerings.

  • Andaz Hotel
  • Hilton Garden Inn
  • Harvest Inn
  • River Terrace Inn
