Intense grapefruit, citrus, and passionfruit forward. "Traditional New Zealand" character.

Where It Lives

• Tropical & Citrus (primary)
  

Storytime

Riwaka is a New Zealand hop named after the Riwaka region. Like many traditional New Zealand hops, it has a sharper, greener, and more herbal character than most American varieties. It’s known for its very bold, punchy lime and grapefruit notes with bright tropical fruit and a lively, sometimes aggressive personality. This green, sharp edge helps it stand out from the rounder, sweeter fruit character found in many modern American hops.

One parallel to help understand the distinctions between NZ and US hops with tropical/citrus/stonefruit-forward traits is that American hops consistently have resin/dank/herbal undertones. "Traditional NZ" hops consistently have green/herbal/sharp undertones, often demonstrated well in (classic) NZ IPAs. Modern juicy NZ hops are much like modern American juicy hops.

Practical Use

Riwaka is mainly used for aroma. It performs well in late boil, whirlpool, and dry hopping, where it delivers strong lime and citrus character. Because it’s quite bold, it can easily dominate a beer if you use too much. A lot of brewers treat it more like a supporting hop rather than the main attraction.

On the dry hop side, 1.5–3.5 oz total in 5 gallons is usually enough for good impact. Going heavier can make the beer feel sharp or one-dimensional. It tends to work best when it has other hops to balance it out.

Best for: Late boil, whirlpool, and dry hopping. Brew day tip: It pairs especially well with Nelson Sauvin, Motueka, or Citra when you want bright, aggressive citrus character.
