I recall a thread on the forum (this one) on the subject of wild hops. As a rule of thumb, wild hops are going to be Goldings, was the conclusion.
I have no idea as to whether this is correct or not, although it seems a very reasonable start point. Since English hops, in English sort of a beer might set you back ã2-ã5 a 40 pint batch, delivered to your door, why, in the name of sanity, would anyone go out of their way to pick, treat, dry and then use hops in a brew that costs them 4 hours + of their life when they know zip about how much benefit they might bring?
To me, a "hop map" is an interesting diversion from actually making any beer. It is a sort of Natural History investigation, rather than anything else.
I have bought 100g of hops for as little as ã1-ã2 and they were perfectly fine, from the perspective of just making beer.
