Pacific Jade hop was created by Pebbbles
Description:
The aroma of this hop is described as “bold” as it delivers a herbal infusion of fresh citrus and crushed black pepper.

Breeding:
Triploid Alpha type developed by the cross of the NZ variety "First Choice" (a relative of the Late Cluster) and an “Old Line” Saazer Male. Released from the New Zealand Hop Research Programme by Hort Reasearch Centre Riwaka in 2004.

Selection:
This variety is the most recent release out of the New Zealand Hop Research Programme selected on its average alpha of 12-14% with Cohumulone in theregion of 24% and an excellent oils profile. The aroma of this hop is described as “bold” as it delivers a herbal infusion of fresh citrus and crushed black pepper. Brewing trials have illustrated Pacific Jade as an excellent hop that delivers a pleasing soft bitterness matched to desirable aroma characteristics.

Brewers Notes:
Suited for use as a bittering hop with some excellent results also being seen in dual purpose applications, with a soft bitterness attributable to the lowcohumulone. The citrus aroma and flavour notes work well to temper malt sweetness in “fullish” Ales especially when used moderately as a finishing hop. Pacific Jade is also well suited to balance dryer Lager styles when employed as an “up-front” kettle addition to showcase its bittering qualities.
