Each wine produced?at Barnett Vineyards is either estate bottled or from a single vineyard in another viticulture district that we have chosen. The wines, therefore, are inextricably linked to the vineyards from which they originate.?The estate vineyards are all located at the top of Spring Mountain and?are planted to Cabernet Sauvignon, Merlot, and Cabernet Franc. The majority of the vineyards are terraced on slopes that are 30 degrees or more. The original estate vines are over 30 years old and are planted on a 6x10 foot grid. In the past few years much of the original vineyard has undergone redevelopment and now vines are spaced at 4x4 feet. The topography is so steep and the plantings are so closely spaced that traditional farming methods such as tractors and disking are not possible. These vineyards are completely farmed by hand from bud break until harvest.
