Riwaka (D Saaz) hop was created by Pebbbles
Description:
Its powerful grapefruit “citrus” characters are literally breathtaking. If you want to say “hops” in your beer, D Saaz says it all. Oil content is almost double that of its Saazer parent.

Breeding:
A triploid aroma type bred during the development of New Zealand hops“hops with a difference” programme. 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 D Saaz 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.
