An heirloom alpha hop that delivers solid bitterness matched to pine and citrus aroma characters (11-14 % AA)
The world's first commercial triploid and highest alpha hop developed by Dr Rudi Robrough by open pollination of the New Zealand developed diploid, First Choice. Released in 1972 from the New Zealand Horticultural Research Centre at Riwaka. (now Plant and Food Reseach).
Originally selected as a high yielding alpha variety Stickbract later became a dual purpose mainstay of the New Zealand Brewing Industry. Aroma is characterised by citrus and pine needles which this heirloom hop carries into the brewhouse and the finished product.
Sticklebract produces quality beers of assertive bitterness while also displaying fine aroma qualities and character achieved from both late and dry hopping additions. Citrus and pine characters make up a large portion of the oils fraction which become quite pronounced at heightened addition rates. This hop works well in big ales or as a background to imperial styles.
“A pedigree hop”
Versatile across several styles depending on addition rates but well suited to big ales and imperial beer styles such as stouts and double IPA’s.
