The Riwaka™ hop is a standout New Zealand variety developed by Plant & Food Research and released by NZ Hops Ltd.

Brewing Characteristics of Riwaka™ Hops

Riwaka™ hops are celebrated for their powerful grapefruit and tropical fruit aroma. Notes of passionfruit, lime, and even hints of diesel give this hop a bold personality.

In the field, Riwaka™ hops are known for their lower yields and more demanding growing conditions. However, their unique profile makes them worth the effort. For brewers, sourcing Riwaka™ hops means gaining access to one of the most aromatic hops available today.
