First and foremost it grows the best of any nz hop I've ever seen. Yield is desceptively low on paper but that is because they are spaced wider because of their extremely long sidearms. The brewing quality is beyond amazing. Words can't describe. But the piney, lemon etc. thing is right on track. Most underrated hope I have grown and brewed with. A gem that not alot of people are aware of.
