The cross was made at Riverside, possibly in the 1950s. The variety was never officially released by the University of California, Riverside, but somehow made it into the public sector. A medium-large size fruit- about like a grapefruit. Dark yellow, thin rind. Dark yellow flesh, almost orange yellow. Too damn seedy for commercial usage but makes a good dooryard juice variety. Very unique flavor; you could love it or hate it. Cocktail trees are large and vigorous. The fruit can vary from the size of an orange to the size of a grapefruit. It has a thin, smooth, yellow rind. The flesh is seedy, yellow-orange in color, and exceptionally juicy. The flavor is pleasantly sub-acid. Cocktail matures in early winter and the fruits hold well on the tree, puffing when they become very old, but not desiccating.
