Brassfield Estate Winery & Vineyard is located in the western section of High Valley at High Serenity Ranch on a truly distinctive and remarkable winegrowing property. Our valley floor vineyards sit at 1800 ft. elevation. The higher vineyard blocks rise to nearly 3000 ft. The temperatures of some parts of this unique vineyard are some of the coldest in California, giving Brassfield a heat summation equivalent to a Region 3 or less in some vintages. In 1973, Jerry Brassfield purchased the original 1,600 acres as a cattle ranch and wildlife preserve. Over the next three decades Jerry acquired additional property. Today, the Lake County estate includes over 2,700 acres across both the eastern and the western sections of High Valley, as well as the Round Mountain Volcano.
