Viticultural Information
Ruby Cabernet
Description
Species: Vitis vinifera Ruby Cabernet is the resulting cross of Carignane and Cabernet Sauvignon made by H.P. Olmo of the University of California, Davis. It is the oldest crossing of wine varieties made by Olmo, released for distribution in 1948. Vines have high vigor on deep, fine, sandy loam to clay loam soils. Vigor is low to moderate on very coarse sands. The canopy tends to be open and shoot growth semi-erect. Vine spacing should be about 7 to 8 feet or more down the vine row for vertical-shoot positioning or standard bilateral cordons. For horizontally divided quadrilateral vines, spacing should be 6 to 7 feet. Ruby Cabernet produces quality wines with good color under optimum conditions, especially at lower crop levels. The wine can have distinctive varietal character. Potential wines can be used for less expensive varietals or as a blend to extend Cabernet or claret-type wines. Some interest in the variety as a premium wine for warmer regions may increase.
