Motueka and Riwaka are New Zealand’s two most widely exported hop varieties beyond Nelson Sauvin, both bred at Plant and Food Research in Nelson, both producing the distinctive Southern Hemisphere citrus-tropical character that distinguishes New Zealand hops from their American counterparts. I’ve used both in pilsner and pale ale recipes where New Zealand hop character is the explicit goal, and the difference between them is clear once you’ve tasted each independently.
Motueka vs. Riwaka: key specifications compared
Motueka: Developed by Plant and Food Research, New Zealand, released 1997. Descended from Saaz, which explains its pilsner-compatible character. Alpha acids: 6.5–8.5% (moderate). Beta acids: 5–5.5%. Cohumulone: 29–33% (moderate). Total oil: 0.8–1.2 mL/100g. Primary components: myrcene (30–40%), linalool (notable), beta-pinene (lime-contributing). Primary flavor/aroma: lime, tropical fruit, lemon, subtle herbal/pilsner note, Motueka’s Saaz heritage is detectable in a background herbal note that makes it uniquely suited to pilsner and lager styles as well as pale ales. The lime character is its most distinguishing feature among New Zealand hops; no American hop produces lime with the same clarity. Riwaka: Developed by Plant and Food Research, New Zealand, released 1997 (same breeding program and release year as Motueka but distinct variety). Alpha acids: 4.5–6.5% (moderate-low). Beta acids: 4.5–5.5%. Cohumulone: 33–38% (moderate-high, harsher bittering than Motueka; use primarily in late additions). Total oil: 0.9–1.4 mL/100g. Primary components: myrcene (40–55%), specific citrus terpenes. Primary flavor/aroma: grapefruit, mandarin, passion fruit, intense citrus, Riwaka is more intensely citrus-tropical than Motueka, with less of Motueka’s lime-herbal character and more of a grapefruit-mandarin intensity. Riwaka is less widely available than Motueka and typically more expensive.
New Zealand pilsner hops: when to use Motueka vs. Riwaka
Use Motueka when: brewing New Zealand-style pilsner or lager where the Saaz heritage of Motueka makes it uniquely compatible with the lager malt base. Motueka-forward New Zealand Pilsner (a recognized BJCP style category) is one of the most food-friendly and distinctive lager styles in craft brewing, the lime-tropical character lifts the noble malt base in a way no European hop achieves. Motueka works at all addition stages in pilsner: bittering (clean at moderate alpha levels), flavor (15 min), and aroma. Also excellent in pale ales and session IPAs where lime character complements citrus hops without duplicating grapefruit (Cascade) or passion fruit (Galaxy) that the recipe already contains. Motueka-Galaxy in a NEIPA is a particularly good combination: Galaxy provides tropical intensity and Motueka adds lime brightness underneath it. Use Riwaka when: you want maximum New Zealand citrus intensity, grapefruit-mandarin-passion fruit character that is more aggressive than Motueka’s cleaner lime profile. Riwaka in a dry hop-forward IPA produces an intensely citrus-tropical result that is distinctly Southern Hemisphere in character. Because of Riwaka’s higher cohumulone, avoid bittering additions, use it exclusively from 15 minutes and later or in dry hopping. Riwaka pairs well with Nelson Sauvin (the two together define the New Zealand craft IPA style) and with Motueka (complementary citrus spectrum, lime plus grapefruit-mandarin). New Zealand hop sourcing: both Motueka and Riwaka are available through specialty homebrew importers in the US, UK, and Australia. New Zealand Hops Ltd exports directly to homebrew distributors. Both are seasonal, the Southern Hemisphere harvest arrives in April-May; order fresh crop when it becomes available and freeze remainder for year-round brewing.
Common Questions
What is New Zealand Pilsner and how does it differ from German or Czech Pilsner?
New Zealand Pilsner is a BJCP-recognized specialty style (category 25A) that uses New Zealand hops (Motueka, Riwaka, Nelson Sauvin, Green Bullet, or Pacific Jade) in an otherwise clean, well-attenuated pilsner base. The key difference from German or Czech Pilsner is the hop character: German Pilsner uses Hallertau, Tettnang, or Spalt for soft, spicy, Noble hop character; Czech Pilsner uses Saaz for earthy, herbal, classic Bohemian character; New Zealand Pilsner uses New Zealand hops for tropical, citrus, lime, or wine-like character that is genuinely distinctive and not achievable with European Noble hops. The malt base in all three styles is similar: pale Pilsner malt, clean lager fermentation, high attenuation, high carbonation, good clarity. The difference is entirely in the hop selection and resulting aroma profile. For homebrewers: New Zealand Pilsner is an excellent project because the tropical hop character from Motueka or Riwaka is immediately rewarding and the pilsner base is well understood. The BJCP style allows up to about 20 IBU from late and dry hop additions in addition to moderate bittering, which gives you flexibility to build New Zealand hop aroma without excessive bitterness. Ferment cold (9–10°C), lager for 4–6 weeks, and dry hop with Motueka at 0.5 oz per gallon during lagering for a genuinely excellent result.
