is a subtropical citrus tree known for its sour to semi-sweet, somewhat bitter fruit. Grapefruit is a hybrid originating in Barbados as an accidental cross between two introduced types, sweet orange and pomelo or shaddock both of which were introduced from Asia in the seventeenth century. When found, it was named the “forbidden fruit” and frequently, it has been misidentified with the pomelo. Grapefruit comes in many varieties. One way to differentiate between varieties is by the flesh color of fruit they produce. The most popular varieties currently cultivated are red, white, and pink hues, referring to the internal pulp color of the fruit. The family of flavors range from highly acidic and somewhat sour, to sweet and tart.
