Green Bullet:



New Zealand Green BulletBreeding:

Released from the New Zealand DSIR (now HortResearch) in 1972 this triploid Alpha Variety was bred by open cross-pollination of the New Zealand “Smoothcone” variety. The era was one where Alpha potential was rapidly being recognised by brewers and the New Zealand Alpha varieties were certainly pushing the boundaries.


Selection can be confusing with New Zealand Bitter types due to aromatic qualities not usually associated with alpha varieties. The Green Bullet has quite high Alpha while it also produces reasonably high levels of oil that complement and balance the very traditional resinous hop character. An excellent bittering variety that is grower friendly due to its yield and late season maturity.

Brewer’s notes:

Although a new variety in relative terms, Green Bullet delivers a very real, traditional bittering quality and hop flavour. A flagship within the New Zealand brewing industry this hop has contributed to several International Brewing Industry Awards.  Considered a bittering variety typically for Lager, Green Bullet also carries a solid Styrian characteristic of subtle spiciness which finds it at home in a freshly drawn pint of Bitter or an Irish-style Dry Stout.
