Considered to be one of the darling hops of the New Zealand craft beer scene, Riwaka’s abundant oil content is nearly twice that of its parent variety Saaz. This unique oil balance alongside a near 1:1 ratio of alpha to beta acids gives it a strong sweet citrus note that, according to one brewer, makes it the “ultimate” for hoppy beers. Riwaka, formerly known as D Saaz, is a product of HortResearch’s New Zealand Hops “hops with a difference” program and was officially released to the brewing world in 1997.
