Super Alpha (also called Dr. Rudi) is a versatile variety with a lemongrass-pine character.

Breeding/Development: New Zealand. Super Alpha (recently renamed Dr. Rudi in honour of the “father of New Zealand hops”) is an elder statesman of the New Zealand craft brewing scene, released by HortResearch in 1976. It is a high-alpha triploid bred from an open cross of Smoothcone.

Brewing Application: Intended as a bittering hop, but like many of its fellow New Zealand varieties that followed, Super Alpha possesses an oil profile that suits modern craft styles very well. Try in hoppy lagers, bitter and pale ale.

Sensory: Moderate. Sweetly grassy with overtones of lemongrass, pine sap, and dried fruit.
