Jackson is a white grapefruit variety with a quite different flavour to the more common White Marsh Seedless. The fruit is sweet and juicy with a hint of tropical lime in the flavour. The level of bitterness is low compared to the usual tanginess of Marsh Seedless. The fruit is more round in shape than a Marsh and has a slightly smoother peel. Jackson grapefruit can be peeled and eaten like an orange as the normal bitterness of grapefruit (caused by naringin) is reduced. Jackson Low Seeded (LS) is a further selection of Jackson.
Good Fruit Guide Rating: ****
Jackson is a very enjoyable grapefruit, which will particularly appeal to consumers who dislike the bitterness of standard garpefruit.
