Brewing Values for Willamette Hops

These are the common ranges that we've seen with Willamette hops over the years. Each year's crop can yield hops that have slightly different qualities, so these number ranges are based on history.

Alpha Acid % (AA)
Alpha acids are the main source of bitterness in beer. Longer boil times will result in isomerization of more alpha acids leading to increased bitterness. Learn more »
5.6% avg
Beta Acid %Beta acids are a component of hop resins responsible for contributing volatile aromatic and flavor properties. Beta acids contribute no bitterness.3.0-4.5%
3.8% avg
Alpha-Beta RatioThe ratio of alpha to beta acids dictates the degree to which bitterness fades during aging. 1:1 ratios are common in aroma varieties.1:1 - 2:1

Hop Storage Index (HSI)The HSI indicates the percent of alpha and beta acids lost after 6 months of storage at room temperature (68°F or 20°C). The freshest hops will always be the best.38% (Fair)
Co-Humulone as % of AlphaLow cohumulone hops may impart a smoother bitterness when added to the boil as opposed to higher ones that add a sharper bitterness to the final beer. Learn more »28-35%

Willamette Hop Substitutions

If the Willamette hop is hard to find or if you are simply out of it on brew day, you can try to substitute it with a similar hop. The old way of choosing replacement hops was done by experience and "feel". There is nothing wrong with that way. However, we wanted to build a data-driven tool to find your Willamette substitutions.

Experienced brewers have chosen the following hop varieties as substitutions of Willamette:

Is Willamette available in lupulin powder?

Unfortunately, there is no lupulin powder version of the Willamette hop. Neither Yakima Chief Hops (Cryo/LupuLN2), Haas (Lupomax) or Hopsteiner have created versions of this hop in lupulin powder form yet. Too bad too - it is pure hop lupulin powder, which leads to huge, concentrated flavor when used in the whirlpool or dry hop additions.
