Wakatu, or Hallertau Aroma as it is sometimes know, is a New Zealand triploid hop with a lot going for it. 2/3 Hallertauer Mittelfrüher and 1/3 New Zealand male, it was released in 1988 from the New Zealand Institute for Plant and Food Research’s hop breeding program.
Its nicely balanced oil profile gives it an understated floral aroma atop pungent fresh lime. Considered largely dual-use, it can be added at any stage of the boil right and dry hopped with success. It has also been noted for its impressive flavor stability.
