Pairing Guide by Style Category
American IPAs (West Coast, Session, Imperial)
- Bittering: Columbus, Magnum, Warrior, Chinook (60 min)
- Flavor: Centennial, Chinook, Cascade (15–20 min)
- Dry Hop: Citra + Mosaic, Simcoe + Amarillo, Cascade + Centennial
- Classic combos: Cascade/Centennial/Chinook | Citra/Mosaic | Simcoe/Amarillo
Hazy / New England IPA
- Bittering: Magnum or Warrior (low — 20–30 IBU max)
- Whirlpool / Dry Hop: Citra + Mosaic, Galaxy + Citra, Mosaic + El Dorado
- Avoid: Columbus at high rates (harsh); Chinook (too resinous for soft style)
- Key principle: All flavor from late additions; bitterness from lupulin powder or low bittering charge
American Pale Ale
- Dual-use: Cascade + Centennial (classic) or Amarillo + Citra (modern)
- Moderate dry hop, showcase citrus/floral character
European Lagers (Pilsner, Helles, Märzen)
- Only noble hops: Saaz, Hallertau, Tettnang, Spalt
- Saaz = Czech Pils | Hallertau = German Pils/Helles | Tettnang = versatile German
- No American hops in traditional lagers
Hefeweizen / Witbier
- Minimal hops: Hallertau, Tettnang, Saaz (5–15 IBU only)
- Hops are background only — yeast esters and spices carry the flavor
Belgian Ales (Tripel, Dubbel, Saison)
- Saison: Styrian Goldings, Saaz, optional spices (coriander, pepper)
- Tripel/Golden Strong: Styrian Goldings, Hallertau Blanc, Saaz
- Dubbel: Styrian Goldings (low rate) — malt and yeast dominate
- New World hops (Nelson Sauvin, Hallertau Blanc) acceptable in modern Belgian interpretations
English Ales (Bitter, Porter, Stout)
- Traditional: Fuggle + East Kent Goldings only
- Modern British: Challenger, Northern Brewer acceptable
- American hops disqualify a beer from "English" style classification
Stouts (American, Imperial)
- American Stout: Columbus, Centennial, Cascade acceptable
- Imperial Stout: Magnum for clean bittering — avoid aroma hops (roast dominates)
- Irish/English Stout: Fuggle, EKG only
Dry Hop Rates (Guidelines)
All rates are total dry hop weight across all varieties combined, not per individual hop.
Split the total across 2–3 varieties as desired (e.g. 15 g/L total = 8 g/L Citra + 7 g/L Mosaic).
| Intensity | Total rate | Application |
|---|
| Subtle | 3–5 g/L | Background aroma, session beers |
| Moderate | 5–10 g/L | Standard IPA, APA |
| Heavy | 10–15 g/L | West Coast IPA |
| Very heavy | 15–25 g/L | NEIPA — commercial standard |
| Extreme | 30+ g/L | Experimental/competition |
NEIPA DDH example (20 L batch):
- First charge (biotransformation, day 2–4): 8–12 g/L total → e.g. Citra 80 g + Mosaic 80 g = 160 g (4 g/L each, 8 g/L total)
- Second charge (cold-side, post-FG): 4–6 g/L total → e.g. Citra Cryo 50 g + Mosaic Cryo 40 g = 90 g (4.5 g/L total)
- Total: ~250 g for 20 L — not 1,200 g
Hop Addition Timing
| Addition | Timing | Purpose |
|---|
| Bittering | 60 min | IBU contribution, minimal flavor |
| Flavor | 15–20 min | Flavor + some aroma |
| Whirlpool/Flameout | 0 min (80°C+) | Aroma + some IBU |
| Dry Hop | Post-fermentation | Pure aroma, no IBU |
Cryo Hops
Cryo hops are concentrated lupulin pellets containing roughly 2× the alpha acids and aromatic oils of standard T90 pellets. Key properties:
- Use ~50% of the T90 weight to achieve the same IBU contribution
- Dramatically less vegetal/plant material — cleaner aroma extraction per gram
- Best used as dry hops for intense aroma without chlorophyll or harsh vegetal notes
- Available varieties: Citra Cryo, Mosaic Cryo, Simcoe Cryo, Galaxy Cryo, Amarillo Cryo, Centennial Cryo
- Typical dry hop rate: 3–8 g/L Cryo ≈ 6–16 g/L standard pellets
When to use: NEIPA and West Coast IPA where aroma purity is the priority. Cost is higher per gram than T90; not necessary for standard beers. Best combined with standard T90 pellets (T90 for volume/oil extraction, Cryo for intensity).
Biotransformation Dry Hopping
Biotransformation occurs when dry hops are added during active fermentation (within the first 2–4 days, at peak krausen). Active yeast enzymatically converts bound hop glycosides into free volatile thiols and other aromatic compounds — creating new tropical/citrus flavour not achievable with post-fermentation dry hopping alone.
Key yeasts for biotransformation (in order of activity):
- London Ale III (WLP066 / Wyeast 1318) — highest thiol conversion; essential for commercial-grade NEIPA
- Conan / Vermont Ale (The Yeast Bay) — strong biotransformation + juicy profile
- Verdant IPA (Lallemand) — strong biotransformation activity; dry yeast convenience
- Voss Kveik (Lallemand) — moderate biotransformation at high temps (25–32°C)
Best hops for biotransformation (highest precursor content):
- Citra, Mosaic, Galaxy, Amarillo — highest bound thiol precursors
- Strata — unique cannabis/tropical profile strongly enhanced by bioT
- Nelson Sauvin, Idaho 7, Talus
Technique:
- Add dry hops at active fermentation krausen (day 2–4 post-pitch)
- Keep at fermentation temperature (17–22°C) for 3–5 days through end of active fermentation
- Allow to reach FG, then cold crash normally
- Optional: second cold-side dry hop addition (post-crash, 0–4°C) for additional fresh aroma
Biotransformation vs cold-side comparison:
| Method | When | Result |
|---|
| Biotransformation (warm-side) | Day 2–4 of fermentation | New tropical/thiol compounds via enzyme conversion |
| Cold-side (post-FG) | After FG, before cold crash | Clean, stable aroma from hop oils only |
| Double dry hop (DDH) | Warm + cold | Maximum aroma complexity — standard for commercial NEIPA |
Hop Substitution Ratios
When a hop is unavailable, adjust weight by alpha acid ratio to maintain equivalent IBU:
substitute_g = original_g × (original_AA% ÷ substitute_AA%)
Example: 30 g Citra (12% AA) substituted with Amarillo (9% AA):
→ 30 × (12 ÷ 9) = 40 g Amarillo
Important caveats:
- The AA% ratio only corrects for bittering contribution (IBU)
- Aroma and flavour character still differs — driven by oil composition (humulene, myrcene, linalool, geraniol)
- For dry hops (aroma-only additions) use the same weight — the IBU ratio is irrelevant for dry hops
- Always note the flavour character shift in brew notes when substituting
