A really fine dual purpose hop with a heady mix of floral and citrus characteristics (6-9% AA)


Released by New Zealand’s Plant & Food Research in 1988 as New Zealand Hallertau Aroma this triploid has parentage of two thirds Mittlefruh and open pollination by a New Zealand derived male.  Renamed Wakatu™ Brand 77-05 in 2011.


During selections this variety displays an intensity of aromas which selectors describe as fresh citrus akin to freshly zested lime peel. These excellent aroma qualities carry right through from selection to the aroma and flavour profiles in the finished beer.


A multi-skilled hop that consistently delivers from kettle to consumer. A true dual-purpose variety with an enviable alpha: beta ratio and oils profile. This all-round brewery performer gives excellent flavour and aroma shelf stability both in small pack and keg.

"Just a great hop"


A versatile hop across several brewery applications and beer styles. Is a real standout out when used in multiple, high addition rates in big ales or in gentle gifts to temper the sweetness of a full malt lager.
