Chancing my luck, but is because you actually did not use Cascade?
Jokes aside, its pretty standard knowledge that hops are possibly the most terroir influenced of all, with the possible exception of truffles, we know far more about hops than truffles with regard to terroir so lets leave that discussion for later.
EKG and Fuggles grow above the cliffs of Dover (well in the vicinity), an area well proved for its hopability, take some cuttings from Zatec or the Hallertau Valley, of course they will flourish but with considerably different results from their source, as indeed EKG planted in Zatec would produce an entirely different profile.
Of course NZ has done very well with research institutes over past number of decades developing unique triploids based on european and american hops, as well as their own varieties. Now I am not saying that China cannot do the same in the future or indeed have not done so already, the only comment I make is..when was the last time the kiwis executed their chief of the FDA for allowing massive fraud, shoddy practices and whatever else just to get foodstuffs, agricultural product and drugs on the market?? Or for that matter the Americans, the Czechs, the Germans, the British or even the Aussies....
I am not knocking the hops btw, I am sure they are fine, just the influence a name may have.
