Mt. Rainier hops were bred by Oregon State University, originating from a cross between Magnum and USDA 19085M. This dual-purpose hop was developed in 1994 and released in 2009, boasting noble aroma characteristics similar to the German Hallertau Mittelfrüh variety but with added bittering strength.
The aroma profile of Mt. Rainier hops includes a mix of citrus, earthy, fruity, and herbal notes. Specific descriptors for this hop are grass, cedar, lemon, and tea, along with noble, licorice, and floral bouquet elements. The unique blend of scents gives it a versatile flavor and aroma that can be used in various stages of the brewing process.
Mt. Rainier hops are well-suited for brewing various beer styles, including lagers, American ales, and porters. Additionally, they work well in German-inspired beers like Pilsners or Helles. They can also add to rich, roasty stouts, providing a subtle, balancing bitterness and complex aroma.

Mount Rainier Hop Oil Breakdown
Hop oils can vary from year to year and farm to farm but based on our research, here are the typical values we have seen reported. This information comes from various hop farms, The Hop Aroma Compendium, and For The Love Of Hops.
|Alpha Acid % (AA)|
Alpha acids are what is isomerized when boiling to create bitterness in beer.
|5% – 8.1%|
|Beta Acid %|
Beta acids are what give hops their more aroma and flavor compounds.
|5% – 7%|
This ratio of alpha acids to beta acids determines how quickly bitterness fades during aging. Lower ratios are common for aromatic varieties.
|1:1 – 2:1|
|Co-Humulone as a % of Alpha|
Higher numbers are said to impart a harsher bitterness.
|21% – 24%|
|Total Oils (mL/100g)|
With more total oils, typically comes a more complex hop profile but these are highly volatile compounds.
|0.2mL – 3.9mL|
|58% – 59%|

|7% – 8%|
|0% – 1%|
|Other Oils: Includes beta-ionine, beta-pinene, limonene, linalool, geranoil & selinene||14% – 18%|
