Traditional hops varieties, Fuggles and Goldings , have been in decline for at least 40 years, mainly because of their management. These varieties are particularly prone to disease, especially mildew which does have a devastating effect on production. Hence many of the traditional Hop Yards where massively expensive pole and wire-work were once seen throughout Herefordshire, Worcestershire and Kent, have been replaced with dwarf hops which as the term conveys are easier to manage, the wire work is only 2 metres high whereas the Older Yards had structures often 5-6 metres high.
These newer varieties have been bred at East Malling in Kent, a one time Government Research Station.
There is a wide range of new varieties most with differing characteristics for aroma, flavour , disease resistance etc. These varieties have genetic material derived from Fuggles and Goldings, which in turn were discovered from wild stocks in the 1700's. There are still a few yards growing fuggles and Goldings, which tend to find there way to local Brewers.
If as suggested hops will become difficult to source in a couple of years( something I doubt), New Zealand has a thriving hop growing industry around Nelson, which could and does supply dried hops to Europe. We are not dependant on the EU for hops.
Dried hops can be stored for sometime providing they are kept at low humidity and free of pests. The problem for growers is storage. Hops are very bulky.
