Willamette is generally perceived as a new, yet good quality aroma hop. The rub of the hops gives an estery/blackcurrant/herbal aroma that is very pleasant but can be quite strong. Differing results have been achieved with this variety. Some brewers have found it to be a suitable replacement for Fuggle, others have had poor results when using it this way but have found that it stands up admirably as an aroma variety on its own merits.
The Willamette cultivar is an aroma variety that was developed in Oregon in the early 1970s. It is a triploid seedling of the Fuggle variety.
Willamette is a moderate yielding aroma variety that matures early to mid-season. Most of the U.S. acreage is in Oregon and Washington. It is somewhat tolerant to downy mildew and has shown good resistance to Prunus necrotic ring-spot virus. Aphid and spider mite controls are not a major problem with this variety.
