Brassfield Estate Winery

Brassfield Estate Winery is a is a vineyard and winery operation in Lake County, California, established by Jerry Brassfield in 1998. Brassfield, who grew up on an alfalfa farm in the San Joaquin Valley, founded GNLD, a vitamin and nutrition supplement company. In 1973, he acquired 1600 acre in the High Valley region of Lake County, California, which he expanded through successive acquisitions, totaling about 2500 acre.

An estate in a neo-Tuscan style was built on the Serenity Ranch on the floor of High Valley. As of 2023, the winery boasted approximately 500 acre under vines, a 1,000-acre nature preserve, and a mile-long network of caves. The winery annual production capacity was around 60,000 cases, or 140000 USgal in 2022.

Brassfield manages several estate vineyards which range in elevation and soil composition: their Monte Sereno vineyard is planted in Franciscan shale at 2,100 feet, the Volcano Ridge vineyard lies at similar elevations in volcanic sands and tephra soils, their Perspective vineyard is on Franciscan shale at 2,900 feet and planted with Syrah and Viognier, and the High Serenity vineyard at 1800 feet on valley soils allows for growing cooler climate varieties like Pinot noir.

In addition to single varietal wines from Cabernet Sauvignon, Grenache, Malbec, Merlot Petite Sirah, Pinot gris, Sauvignon blanc, Tempranillo, Viognier or Zinfandel, Brassfield produces two signature blends: their red Eruption, a blend of Cabernet Sauvignon, Syrah, Malbec, Petite Sirah, Mourvèdre, Grenache and Zinfandel from their Volcano Ridge vineyard; and Serenity, a white blend of Pinot gris, Sauvignon Blanc, Viognier and Gewürztraminer grown in gravelly valley soils.
