BOR

Selected by Dr Bob Romanko, BOR 704 was so named for it’s planting position, row 7, plant 04, in the Prosser “Bone Yard” in the Yakima Valley. It features an aroma profile that is distinctly European. While BOR exhibits a relatively poor yield, it has been used to breed other seedlings in an effort to pass on its low cohumulone rate that is sometimes as low as 14%. However, its low alpha content has hindered it from gaining any successful foothold in commercial hops production.

There seems to be some confusion over its parentage. Some sources say it’s a seedling of Hallertau Mittelfrueh while others say it is of Czech Saaz and Northern Brewer descent. The former is most likely true.
