New Zealand grown US aroma cultivar with mild and pleasant, slightly spicy floral tones (4-6 %AA)


Willamette Hops are the most widely grown aroma hop in the US; released from the USDA breeding program in 1976. They are named after the mighty river that pours through the Willamette Valley in North Western Oregon. Willamette Hops are a triploid seedling of Fuggle, which is a quintessential English variety that has shaped decades of beer brewing.


Willamette is an aroma hop variety with a low alpha acid content at 4.0%-6.0%. Although Willamette can contribute slightly to the bittering of a homebrew or craft beer, Willamette dominates its usage for its flavor and aroma and is noted for its mild and pleasant, with slightly spicy and floral tones.


Typical Beer Styles: Used in both American and English-style ales.
