You've just described something I've been trying to find the words for for quite some time. I've always compared it to prickly carbonation but finer. You've nailed it. So THAT'S what the cause is?
I reckon it is - but don't quote me on it... there are a lot of professionals out there who think that it is a load of crap. I started using lower cohumulone hops for bittering about a year ago, and noticed the difference instantly.
Not necessessarily mate. For whatever reason - argonomics etc. NZ hops have a comparitively higher "Black Pepper" oil about them - I think it's the Carophyllene oil... again dont quote me on it. But you'll agree that even though NZ Cascade and US Cascade have the exact same genetic background - the NZ Cascade is noticably more peppery.
If you want nice bittering from NZ hops - go for these varieties:
Out of all of those id have to pick Southern Cross cos of the high alpha acid, makes it cheaper..
But what about Super Alpha? JT is gonna be pissed you didnt suggest that :oP lol

Nah, that's the good thing about brewing Rev, you can be completely comfortable with every recipe and ingredient that you like - because it suits your taste
It'd be a boring ol' world if we all only brewed the same Dopple-Imperial hop-ass NZ draught-weizen recipe eh ?
To be fair, Super Alpha is only moderate: 36 - 39% and I think it's important to note that below 35IBU you aren't really going to notice too much harshness. Green Bullet, on the other hand... 42%... ouch!

No correection needed Rev - everyone looks for something different from their beer & ingredients I'm sure.
Now off to work on a recipe for the Dopple-Imperial hop-ass NZ draught-weizen !
*edit, the Noir version of course, for winter sipping by the fire.
Then late winter / early spring I'll be working on the lo-carb Kristal version for summer
