Haven't had all the latest brews... we don't get much better than Tui here in New Plymouth. I'll be in CHCH on Wednesday and Thursday next week... so might get to have a try then.
I'm sure there is much more difference then my uneducated palate discerns....
I get more citrus grapefruit from Riwaka and a little more spice / herb tones, where as Rakau is more stone fruit / passion fruit. Rakau sounds nice, but I have never used it by itself.
After drinking last night a sensational Mikeller Single Hop Nelson Sauvin last night I thought I will pay homage to this hop and Brew a all Nelson Sauvin Blonde
87% Global Pils
8% Global Light Caramel
5% Wheat
65 Degree Mash
60g Nelson Sauvin from 30 mins and Less giving me 28Ibus
Yeah its all you need for a simple easy drinking ale. The more complexe the grain or hop bill is, the more you have to do to the beer to get it drinking spot on!
