Pacific Gem:

Available in either conventional or organic form Certified organic - Bio Gro New Zealand

New Zealand Pacific GemBreeding:

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 HortResearch and released in 1987.


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.

“A master of consistency”
