Idaho Gem Hops

Published on

Idaho Gem is a unique hop variety from Gooding Farms in Wilder, Idaho. Though its genetics remain a mystery, this exceptional hop has quickly gained traction in the craft beer world for its versatility and striking flavor profile. Idaho Gem is well-suited for use as a single hop but also pairs brilliantly with other popular hops such as Citra, Mosaic, Sabro, and BRU-1.

This great hop is known for having sweet, fruit-forward aromatic oils. The aroma and flavor characteristics of Idaho Gem are marked by a bright and forward impression of fruit candy, reminiscent of Juicy Fruit or Jolly Ranchers, and supported by citric grapefruit notes. The hop also delivers hints of berry, bubblegum, citrus, floral, and mint undertones, adding complexity and depth to its flavor.

Given its exceptional qualities, Idaho Gem is well-suited for a wide range of beer styles. It is particularly effective in late kettle additions or dry hopping. At least five beer styles that benefit from including Idaho Gem are:

  • Hazy IPAs.
  • Fruit-forward pale ales.
  • Juicy New England IPAs.
  • Citrusy West Coast IPAs.
  • Refreshing summer ales.

Idaho Gem 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.
11% – 14%
Beta Acid %
Beta acids are what give hops their more aroma and flavor compounds.
5% – 7%
Alpha-Beta Ratio
This ratio of alpha acids to beta acids determines how quickly bitterness fades during aging. Lower ratios are common for aromatic varieties.
2:1 – 3:1
Co-Humulone as a % of Alpha
Higher numbers are said to impart a harsher bitterness.
40% – 45%
Total Oils (mL/100g)

These substitutions aren’t perfect as hop chemistry is pretty complex.

We wanted to make this list of substitutions with varietals that are easy to find when possible. For Idaho Gem, we recommend substituting with the following hops:
