1. Start with the hop's role
Decide whether the original hop is there for bittering, late flavor, whirlpool aroma, or dry hopping. Bittering swaps can be adjusted with alpha acid math, while aroma swaps need closer flavor fit.
- Bittering addition: compare alpha acid and timing
- Late addition: compare flavor direction
- Dry hop: prioritize aroma over exact IBU math
2. Match the style expectation
IPA and pale ale substitutions can usually lean citrus, tropical, pine, or resin. Lagers need cleaner herbal, floral, or spicy hops. Stouts and porters usually need restraint unless the recipe is intentionally modern.
- IPA: citrus, tropical, pine, resin
- Lager: noble, floral, herbal, spicy
- Stout or porter: earthy, woody, subtle citrus when appropriate
3. Adjust the recipe after choosing
If the substitute has a different alpha acid percentage, adjust bittering weight in the IBU calculator. For late additions and dry hops, start with a similar weight and adjust based on intensity.
- Use package alpha acid when available
- Adjust bittering additions first
- Keep notes so the next version is easier
