Northdown was bred at Wye College in Kent, England as higher alpha acid alternative to the hops of the time (1970s). A result of breeding Northern Brewer and an unknown German varietal.
Dwarf variety hops grow shorter in height than traditional varieties but, importantly, produce the same yield. This combination makes harvest easier.
Explanations
Storage: is based on the percentage of alpha acids remaining after 6 months at 20*F.
Oil composition percetages are based on the total percentage of oil in the hop. Example: 10 - 20% means that for the specific oil it is 10 - 20% of the overall oil make up.
