I've tried Topaz, Ella, Enigma, Summer ( discontinued and will not be planted / available again - it's a shame, it was good ), Galaxy and Vic Secret. These are all AUS hops. I enjoyed Summer, Topaz, Enigma and Vic Secret. Ella and Galaxy can be weird and wrong at times, at least this was my experience. Vic Secret is nice both boil and DH. Topaz shines best in the kettle and WHP. Dry hopping with Topaz can release lots of grassy notes and it is really strong, so I save it as a kettle hops. Enigma is interesting - it has something I cannot put my finger on, and I am still wanting to try it again a few more times.
From the NZ hops, I've tried Motueka, Nelson Sauvin, Pacific Jade, Southern Cross, Pacifica, Rakau, Riwaka, Taiheke ( Cascade - but it no longer ressembles the US Cascade ), Wai-Iti, Waimea, Wakatu. I've enjoyed Motueka, Pacific Jade, Southern Cross, Pacifica, Taiheke, Wai-Iti and Wakatu. The rest were not amongst my favourites, but then again, I need to brew more batches.
