Seedling of WGV crossed with O.B.79 at Wye College in 1951. Progress was released for commercial production until 1964. Its Verticilium Wilt tolerance make it an ideal replacement for Fuggle. As it was bred as a replacement for Fuggle it has very similar characteristics. Slightly sweeter and with a slightly softer bitterness it is has excellent potential at both the start and end of the boil.
