The award-winning Blanc du Bois grape is considered one of the best choices for winemaking. It's a hybrid variety: European grape combined with a native Florida grape. Blanc du Bois performs well in the Southern states due to its ability to hold up well in heat and humidity. Zones: 5-9. This is an American hybrid grape that was created in 1968 by John A. Mortensen at the University of Florida by crossing various Vitis vinifera grape varieties such as Golden Muscat with native Florida varieties. When released in 1987, Blanc du Bois became another grape variety in the small but growing number of vine types that can both produce marketable wine on their own yet can withstand bacterial infection that destroys nearly all vinifera vinestocks imported into the southern United States. Grown in coastal areas in the southeast United States (South Carolina to Texas) and north into the Texas Hill country. Adapted to alkaline and high salt soils.
