Among the following, which hop is NOT included in the list of New Zealand hops?

Cascade is not a New Zealand hop; it originated in the United States. Specifically developed in Oregon in the 1950s, Cascade hops have become one of the most popular varieties used in American craft brewing, particularly known for their floral, citrusy aroma and flavor.

On the other hand, Pacific Gem, Wakatu, and Riwaka are all bred in New Zealand and are known for their unique characteristics. Pacific Gem is appreciated for its rich complexity, often exhibiting dark fruit and berry-like flavors. Wakatu is recognized for its delicate floral and citrus notes, while Riwaka is celebrated for its intense tropical fruit aroma. Each of these hops contributes distinctly to the New Zealand hop profile, which is revered in brewing for its unique expressions of flavor and aroma.
