Name a hop variety that comes from New Zealand.

Green Bullet is a hop variety that originates from New Zealand. This hop is known for its high alpha acid content and is typically used in brewing for its bittering properties. It can also impart distinctive flavors and aromas that are characteristic of New Zealand hops, often described as fruity, spicy, and even herbal.

The other varieties listed—Chinook, Cascade, and Liberty—are primarily associated with the United States. Chinook is known for its strong pine and grapefruit characteristics, Cascade has become famous for its floral and citrus notes typically used in American ales, and Liberty is recognized for its mild, floral aroma and used largely in German-style lagers. Therefore, Green Bullet is the correct choice as the only hop variety listed that comes from New Zealand.
