‘RubyCrisp’ is a muscadine grape (Vitis rotundifolia) that was released by the University of Georgia (UGA) College of Agriculture and Environmental Sciences (Athens, GA). ‘RubyCrisp’ produces high yields of large-sized berries with excellent taste and texture. ‘RubyCrisp’ berries are dark red in color, which is distinct from the normal bronze and dark purple colors of most muscadine cultivars. ‘RubyCrisp’ has hermaphroditic flowers and produces berries of similar size to those of the largest female cultivars (≈15 g). ‘RubyCrisp’ has a midseason harvest date with an average first pick on 21 Aug. in Tifton, GA. ‘RubyCrisp’ has a low percentage of dry pedicel scar and is not recommended for commercial packing for this reason. Excellent texture, attractive and unusual color, and overall eating quality suggest ‘RubyCrisp’ berries will be an ideal home-garden and pick-your-own cultivar.
