Mellow Yellow® Hops
AromaAlpha 4.0 - 6.0%New Zealand
Flavor & aroma
Mellow Yellow® is a captivating heritage variety that tells the story of German brewing traditions taking root in the fertile soils of New Zealand. Bred by Wild About Hops from Hallertauer Hersbrucker seeds brought to the islands by 19th-century immigrants, this variety has spent generations adapting to the unique New Zealand terroir. While it remains a close relative of the classic Hallertau family—virtually indistinguishable from Mittelfrüh in its structural elegance—it has developed a vibrant, zesty edge that is purely Kiwi. The result is a hardy, vigorous grower that provides brewers with a bridge between Old World "Noble" sophistication and New World fruit intensity.
The sensory profile of Mellow Yellow® is a refined and luminous arrangement of traditional European spice and bright Southern Hemisphere fruit. True to its name, it leads with a primary, "mellow" bouquet of lime zest, fresh hay, and delicate wildflowers, followed by a sophisticated secondary layer of white Riesling grape and ripe gooseberry. As the profile develops, brewers will find a pleasant, polished bitterness and a subtle peppery snap that remains incredibly smooth on the palate. Thanks to its balanced oil composition and noble pedigree, it delivers a clean, integrated bitterness—driven by low cohumulone levels—and a crisp, slightly vinous finish.
If you can't find Mellow Yellow, the best alternatives are Hallertau, Hersbrucker, Liberty, or Wakatu™.
