Originally known as SuperAlpha, the variety was renamed to Dr Rudi in 2012. It was bred from New Zealand Smooth Cone and is largely grown in New Zealand. It was originally released in 1976.
Considered a bittering hop, Dr Rudi is now widely regarded as dual-use and features a grassy, piney, citrus character. It is also well known for its clean and crisp bittering despite its high cohumulone content. Works well in single-hopped beers.
