Just south of Buellton along Santa Rosa Road is part of the old Rancho de la Vega property, which was purchased by the Mosby family in 1976. Prior to that, in 1971, a vineyard was planted and the winery known as Vega Vineyards emerged as one of the first Santa Barbara County wineries. In 1980 the name was changed to Mosby Winery.  See video at VineStories.

Driving past the rock-walled entrance adorned with the Mosby family crest, visitors get the sense that they are going back 100 years in time. Giant sycamore and ancient oak trees shade several picnic tables, and a palm tree stands across from a 25-foot-tall cactus in this rustic, authentic setting. Just ahead is an old California adobe built in 1853 as a ranch house that is now home to the Mosby family.

To the right is the historic carriage house, built in the 1880s, that now functions as the tasting room. Fully restored in 1978, the space is still permeated by the rustic atmosphere of old California. The wines are Cal-Italian and include Grappa, plum and raspberry brandy, and a sparkling wine. Other offerings include Cortese, Pinot Grigio, Traminer, Sangiovese, Dolcetto, Primitivo, and Teroldego. Be sure to check out the artist series wine labels by acclaimed artist Robert Scherer.
