Barnett Estate Vineyards are all located at the top of Spring Mountain. The majority of the vineyards are terraced on slopes that are 30 degrees or more. The original estate vines are now 22 years old.

The topography is so steep and the plantings are so closely spaced that traditional farming methods such at tractors and disking are not possible. The Estate Vineyards are complete farmed by hand from bud break until harvest. The vineyards are planted to Cabernet Sauvignon, Merlot and Cabernet Franc.

Rattlesnake Hill and Spring Mountain District Cabernet Sauvignons are the focus at the estate with total Cabernet production varying between 2,100 and 3,000 cases annually. In addition, Barnett Vineyards produces limited amounts of Merlot, Pinot Noir and Chardonnay grown from single vineyards located in well-desired appellations.
