Also known as Dr Rudi.
Super Alpha was bred from the New Zealand Smooth Cone variety and enjoys its popularity primarily in New Zealand. As the brewing industry has changed, Super Alpha has gone from a strictly bittering hops to a dual-use hop as its grassy, piney, citrus character became noticed. It is known for its clean and crisp bittering despite its fairly high cohumulone content of up to 39%. This hop has recently been renamed to Dr Rudi.
