The Red Grapefruit has a rind that is yellow-orange with a blush of rose indicating ripeness. The peel is medium-thick and bitterweet laden with volatile oils that intensify when the rind is punctured or zested, releasing a bouquet of citrus aromatics. This grapefruit has the darkest flesh of all the red grapefruit varieties. In fact, the redder the flesh the sweeter the flavor. The ruby red pulp is juicy with a sweet-tart flavor and contains few, if any, seeds.
