Four Sisters Ranch Vineyards and Winery, located in the northern Paso Robles AVA, have been family-owned and operated for over twenty-six years.

A family affair, the winery is owned and operated by Serena Friedman, M.D. and Michael Drucker, M.D., and is named after their four daughters – the Four Sisters – who contribute uniquely to the winery’s success.

Their 450-acre vineyard produces bulk and private-label wines for many renowned wineries in the Napa Valley and internationally. From its inception, Serena and Michael have been hands-on vintners who are involved in every stage of the wine-making process.

Four Sisters strongly believes in taking care of their surrounding environment through the winemaking process, and they continue to learn and refine their techniques to accomplish this.

Their commitment to sustainability has seen the following practices adopted throughout their vineyard:

• Drip irrigation for our grapevines, which controls and preserves our water
• Erosion control using natural barriers
  Reduced use of pesticides
• Strategically placed owl boxes for safe and natural pest control throughout the vineyards
• Use of Weed Seeker and Rodinator equipment to control weeds and rodents without use of toxic chemicals
