Mission Guided by more than twenty-five years of grape growing and winemaking experience, Mercer Estates aspires to create outstanding wines that exceed your expectations. Company Overview We are now into our fourth generation of farming in Washington State\'s Horse Heaven Hills. We look back to earlier generations with respect and appreciation for the work they did and the legacy they established. Sustainability and conservation are not new ideas for our family - demonstrated by our history and 1,100 acres of habitat. It is our goal to continue to shepherd this land and lead the next generation proudly in the same direction. One of the great joys of farming is sharing the wines that exemplify the many interesting qualities of this land. The Mercer Estates winery and tasting room is located in Prosser, Washington. Our wines are produced from premium grapes grown throughout the Horse Heaven Hills (primarily Cabernet Sauvignon, Merlot, Syrah, Mourvedre, Malbec, Sangiovese, Petit Verdot and Grenache), Yakima Valley (primarily Chardonnay, Riesling, Sauvignon Blanc and Pinot Gris) and the greater Columbia Valley.
