Mosby winery is committed to producing award-winning Cal-Italian wines. Bill and Jeri Mosby purchased the old de la Vega land in the early 1970s, and the first thing Bill did was plant vines. The Mosby’s first commercial wines were bottled under the Vega label, named after the old Spanish California land grant. Bill’s wine began to gain industry attention, and a following of Mosby wine enthusiasts continued to develop. In 1986, at his family’s insistence, Bill changed the Vega label to reflect the Mosby name and winemaking philosophy.
