Cabernet blanc is a white German and Swiss wine grape variety that is a crossing of the French wine grape Cabernet Sauvignon and an unknown hybrid grape variety. The grape was bred by Swiss grape breeder Valentin Blattner in 1991. Cabernet blanc has strong resistance to most grape disease including botrytis bunch rot, downy and powdery mildew and tends to produce loose clusters of small, thick-skinned grape berries which can hang on the vine late into the harvest season to produce dessert wines. Today the grape is found primarily in the Palatinate wine region of Germany with some experimental plantings in the Netherlands.
The grape is currently not being used for commercial wine production in the United States with American wines labeled as Cabernet blanc or White Cabernet instead being sweet pink-colored blush wines made from early pressing of Cabernet Sauvignon grapes similar to how White Zinfandel is produced from the red Zinfandel grape.
