About Us / Mt. Brow Winery History: Our winery, which is family owned and operated, is located in Tuolumne County, California in the foothills of Central Sierra Nevada Mountains. We have a long growing season with warm days, cool nights and dry climate. We believe that these conditions, along with much tender loving care, generates rich, fruity flavors, and excellent color. Jim Costello is the winemaker, business manager, and overall ‘godfather’. He was inspired by his Grandfather who was born in Italy and often spoke, with a twinkle in his eye, of making wine in the ‘Old Country’.
