The 460-acre Rancho Santa Rosa estate vineyard features 230 acres of vines that climb from 500 to 1,000 feet above sea level. The soils are maritime-based and the weather is consistently cool thanks to moist ocean breezes that sweep the property daily. The vineyard is farmed with the painstaking care and attention usually associated with much smaller vineyards. In fact, the Rancho Santa Rosa Vineyard was originally conceived as individual micro-vineyards delineated into 59 unique blocks based upon soil type, exposure, elevation, grade, rootstock and clone. Rancho Santa Rosa produces remarkably rich and silky wines.
