MOD: Description inserted by Lord Raja Goomba I, to ensure hop descriptions are at the top of these hop topics. Original post below:New Zealand Pacific Gem
Available in either conventional or organic form
A Triploid Alpha type bred from the New Zealand variety “Smoothcone” crossed with Californian Late Cluster x Fuggle. Developed through the hop breeding programme of the New Zealand Horticultural Research Centre known now as HortReseach and released in 1987.
Selection:
Does not carry the punchy aromas usually associated with higher Alpha hops. Pacific Gem contains a good balance of oils which constantly contributes to its aroma score. A very pleasing hop with useful bittering potential with Alpha Acids at 13 % and above.
Brewer’s notes:
Pacific Gem fills the brew house with enticing aromas during kettle addition and has been described as producing oaken flavours with a distinct blackberry aroma. Typically used as a first hop addition and makes its presence felt through an excellent tempered bitterness and flavour. Well suited to a wide range of beer styles and lends itself well to European Lager styles of various bitterness levels.

I'm starting this thread because I haven't seen much Pacific Gem details around aside from some details pasted from the growers details and I feel it needs more attention.
I've used pacific gem in quite a few ales, but I've just started drinking IPA that is basically just pacific gem cube hopped and I'm seriously impressed with it. I've used pacific gem in that many ales but never really was able to pick the specific flavour, though I've always enjoyed the beers it is in.
Sipping this beer (roughly 95% JW vienna, 5% JW trad ale, and 80g cube hopped pacific gem @13.5%AA) I'm finally able to define it's flavour. From this beer I will taste the following.
earthy/grassy/woody
spicy/ginger
berry (blackberry?)
Slight tropical fruit flavour (pineapple)
In terms of flavours it works very well as an english style hop. I think it is similar to fuggles but with less of the aniseed/licorice flavour and a blackberry very slight pineapple flavour. It also has quite a strong spicy/ginger characteristics similar to styrian goldings.
Only issue I have with it is that at such a high AA% you can't overload it too much, but that's not an issue unless you are going for an american style ipa.
What are other people's experience with it?
