Sticklebract Hops came from the breeding program at the DSIR Research Station in New Zealand. Sticklebract was released in 1972 and is a cross between First Choice X Open Pollination. In 1960 First Choice was part of a breeding program that helped to wane the disaster that was happening with Black Root Rot on the main variety at the time, Late Cluster.
Sticklebract is a dual use hop with a high alpha acid content around 13.0%.and provides a healthy bottom line to the bitterness levels in a brew. Stricklebract is compared to Nothern Brewer and provides robust aroma contributions. A high level of selinine is associated with the piney citrus character. It also comes with high levels of myrcene oil and registering levels of farnesene oil. Much like Northern Brewer, Sticklebract is versatile from boil to dry-hop in the beer brewing process.
Sticklebract is a strong yielding plant, and the medium to large hop cones are harvested mid to late season after a vigorous growing cycle.
Sticklebract is commonly used for both its aromatic qualities as well as its bittering qualities. It has Simcoe similarities of pine with a Sorachi Ace lemon zest. It is popular with breweries in the UK and Poland.
