Riwaka:

   
Available in either conventional or organic form Certified organic - Bio Gro New Zealand

New Zealand D SaazBreeding:

A triploid aroma type bred during the development of New Zealand hops “hops with a difference” programme. Motueka (formerly B Saaz) also came out of this plant-breeding strategy through crossing “Old Line” Saazer with specially developed New Zealand breeding selections.  Released by HortResearch Riwaka Hop Research Centre in 1997.

Selection:

The Riwaka is a real standout during selection especially when “rubbing up” the freshly kilned cones for aroma scores.  Its powerful grapefruit “citrus” characters are literally breathtaking.  This variety is typically seen to have higher then average oil, almost double that of its Saazer parent. 

Brewer’s notes:

If you want to say “hops” in your beer than this variety says it all. The pure weight of the oil character experienced during selection carries right through to the glass. A punchy addition to the new-world styles of Pale Ale and regional Pilseners. A cult hero that is established in the New Zealand craft beer culture.

“A bold hop that makes a statement”
