well just to confuse things, there are New Zealand Willamette too.. (Not discussed in depth though) if it's anything like their Cascade version V's US/AU it'd be the pick of the bunch.. not tried it though and any NZ hops for me is about 3 weeks away at a guess.
Im pretty sure I asked about US Willamette last week, still awaiting a reply so I cant give an ETA in all honesty but AU shouldnt be hard to lay my hands on.
Been a bit crook this week so I havnt been on the ball as much as would be the norm, but I'll get onto it early in the week.
