Spring Mountain Vineyard is an 845 acre estate on the eastern slopes and lower half of Spring Mountain. It extends from 400 feet above sea level to about 1450 feet at the top of the property. There are about 135 different vineyard blocks scattered over the estate totaling 226 acres. Each has a different elevation, soil, and exposure to the elements and each block produces something unique. This great diversity of steep hillside plantings is the source of consistent, powerful, and distinctive red wines.
Four adjoining properties on Spring Mountain were acquired, each featuring a vineyard and a winery. They were Spring Mountain Vineyards (Miravalle) 257 acres, Chateau Chevalier 120 acres, Streblow Vineyards (Alba) 33 acres, and Draper Vineyards (La Perla) 435 acres.
These wine properties were first developed in the late 19th Century and, though boundaries and names had changed in the intervening years, much of what was done a century earlier remains evident today.
Spring Mountain Vineyard has been a sustainable wine estate since 1992 when it came under new ownership and direction.

A strong west wind drift brings cold water to the California Coast. It also drives water westward from below the Aleutian Islands toward the shore of Southern British Columbia. This current splits as it hits the North American coastline. The current that heads north...
