well used in blending. Medium bitter. Late to ripen. Diploid

Bramley's Seedling  -  An English sharp. Actually a dual purpose apple, culinary and cider. Originated in England in early 1800's. Although very sharp when eaten raw, surprisingly, the Bramley has quite a reputation in Ireland and England as a varietal. To be sure, though its major value is in blending. Very sharp. Late summer ripen. Triploid

Brown Snout  -  Another British seedling of unknown parentage. This bittersweet variety is commonly used as both varietal and blending. Medium soft bitter. Late to ripen. Diploid.

Kingston Black  -  English bittersweet or bittersharp dependending on particular growing conditions. Originated in early 1800's.

In this growers mind the best varietals made from this apple are when produced on the bittersharp side, producing a cider slightly on the sharp side.
