Hop substitution is a practical skill every homebrewer needs. A recipe calls for Citra, your homebrew shop is out, and you need to decide what to use instead. Or you have a large bag of a hop you love and want to incorporate it into a recipe designed for something else. Or you’re trying to replicate a historic recipe that calls for a variety no longer produced commercially. The key to good substitution is understanding what each hop contributes, alpha acids for bitterness (easier to substitute), and specific oil compounds for aroma (harder to match exactly).
How to approach hop substitution
Bittering additions (60-minute boil additions) are easy to substitute, any hop at adjusted weight to match IBU contribution works. The aroma oils that define the hop’s character largely volatilize during a long boil. Use the formula: weight_substitute = weight_original × (alpha%_original / alpha%_substitute) to match IBU contribution.
Aroma and dry hop additions (late boil, whirlpool, dry hop) are harder, the specific oils (myrcene, linalool, geraniol, farnesene, etc.) in each variety produce unique aromas that can’t always be replicated. The best substitutions use varieties from the same geographic and genetic family: American C-hops substitute reasonably for each other; New Zealand varieties share some tropical character but have a distinct profile; English varieties substitute within their family.
Hop substitution chart by variety
| Hop variety | Character | Best substitutes |
|---|---|---|
| Citra | Tropical, citrus, passion fruit, lime | Mosaic (closest), Simcoe (earthier), Azacca, Galaxy |
| Mosaic | Blueberry, tropical, earthy, herbal | Citra (brighter), Azacca, Centennial + dry fruit |
| Galaxy | Passion fruit, peach, citrus, tropical | Citra, Mosaic, Vic Secret |
| Simcoe | Pine, citrus, onion/garlic (high amounts), earthy | Chinook (similar pine), Columbus + Amarillo |
| Amarillo | Orange, grapefruit, floral, apricot | Cascade (similar citrus, lower alpha), Centennial |
| Cascade | Grapefruit, floral, spicy | Centennial (more intense), Amarillo (more orange) |
| Centennial | Floral, citrus, grapefruit, resiny | Cascade (milder), Columbus (more bittering) |
| Columbus/CTZ | Earthy, spicy, resiny, high alpha | Chinook, Nugget (bittering), Zeus |
| Hallertau | Spicy, herbal, floral, noble | Tettnang, Saaz (slightly spicier), Liberty |
| Saaz | Herbal, earthy, spicy, classic noble | Hallertau, Tettnang, Sterling |
| East Kent Goldings | Earthy, floral, honey, classic English | Fuggles (earthier), Styrian Goldings |
| Fuggles | Woody, earthy, herbal, mild | EKG (more floral), Willamette |
| Vic Secret | Pineapple, passion fruit, pine | Galaxy, Citra, Topaz |
Adjusting weight for alpha acid differences
Always adjust substitute hop weight to match the original IBU contribution. Example: a recipe calls for 2 oz Citra at 12% alpha for bittering. You’re substituting Cascade at 6% alpha. Weight needed: 2 oz × (12% / 6%) = 4 oz of Cascade to produce the same IBU contribution. For aroma additions where IBU contribution is minimal, you can substitute at similar weights or slightly more if the substitute has lower oil content.
Common Questions
Can I substitute a blend of hops for a single variety?
Yes, and sometimes blending produces results closer to the original than a single substitute. Citra’s tropical-citrus character can be approximated with 60% Mosaic + 40% Amarillo for aroma additions, Mosaic contributes tropical and blueberry, Amarillo adds the citrus-orange dimension that Mosaic lacks. Similarly, Simcoe can be approximated with Chinook (pine, resin) + small Amarillo or Citra addition (citrus dimension). When a hop variety is genuinely unique and nothing single-handedly replicates it, blending component varieties is the most sophisticated approach.
Does hop freshness matter for substitution decisions?
Significantly, old hops lose aromatic oils faster than alpha acids, meaning an aged hop may have similar bittering power (measured alpha %) but substantially diminished aroma contribution. If you’re substituting with older hops from your freezer, use them for bittering additions where aroma matters less; purchase fresh hops for dry hopping and late additions where oil content drives the flavor. Check the harvest year on your hop packages and prioritize current-season or previous-season hops for aroma use. Most homebrew shops stock hops packaged with harvest year, buy fresh and store sealed in the freezer between uses.
