Summit™ is a high-alpha American dwarf hop whose current supplier profile includes citrus, stone fruit, herbal and woody character. Yakima Chief Hops says it was bred by the American Dwarf Hop Association, released in 2003 and is used mainly for bittering. Treat claims about any guaranteed onion, garlic or orange outcome as hypotheses to test rather than fixed properties of every lot.
Summit identity and typical values
| Field | Yakima Chief reference | Recipe implication |
|---|---|---|
| Breeding code | AD24-002 | Keep the code with old recipe records |
| Aroma groups | Citrus, stone fruit, herbal, woody | Define the intended late-hop role before replacing it |
| Alpha acids | 15–17% | Efficient for bittering; calculate from the packet |
| Beta acids | 5–6.5% | Reference range, not a lot result |
| Total oil | 1.5–3 mL/100 g | Not a direct dosing formula |
Replace an early Summit charge by calculation
For a hypothetical recipe using 25 g of Summit marked 16% alpha acids, an available bittering lot marked 13% gives:
25 × 16 ÷ 13 = 30.8 g
This assumes the same product form, boil time, wort volume and utilisation model. It equalises labelled alpha-acid mass, not measured IBUs or flavour. Use the hop substitution calculator with the actual lot values and sensible scale precision.
Handle late-hop character as a separate experiment
A broad “orange-citrus alternative” label hides Summit's herbal, woody and stone-fruit dimensions. If citrus is the only required outcome, say so in the recipe brief. If the supporting herbal or woody character matters, compare candidates against those attributes too. Do not transfer the bittering ratio to a late or dry-hop addition.
Use a coded small-volume screen with equal product form, mass per litre and contact conditions. Record citrus, stone fruit, herbal and woody intensity separately. Note savoury descriptors if they occur, but do not prompt assessors to report them or claim they are inevitable.
Sources and limits
This article addresses Summit itself. Other named varieties retain their own replacement pages and query intent. BrewMyBeer has not brewed the compared lots or established a universal late-hop result. Save observations in Beer Lab and use the hop replacement guide for the wider method.
Learning check: should the 30.8 g bittering result become a dry-hop dose?
No. The calculation uses alpha-acid percentages and fixed bittering assumptions; it does not equalise aroma.
