Draft Beer (Golden 7:3 Foam Ratio) Broth Ratio & Extraction Phase SOP (Extraction Timeline)
Beverage — no broth. Phase 1 — Keg conditioning (passive): Maintain keg at 4°C, CO₂ at 2.2 bar for 24h minimum before service. Phase 2 — Glass prep (10s): Frost mug at −8°C freezer — warm glass kills foam (−25 Hosokawa). Phase 3 — Pour protocol: 45° tilt → vertical at 70% fill → reverse lever for 3s micro-foam cap. Total pour 12–15s. Foam must hold 90s minimum.
Draft Beer (Golden 7:3 Foam Ratio) Noodle Firmness & Drain-Shake Technique (Noodle Texture & Water Shaking)
N/A — pour timing replaces noodle boil. 45° tilt pour: 8s. Vertical main pour: 4s to 70% line. Foam tap: 3s. Deviating ±2s on foam phase shifts ratio from 7:3 to 6:4 (−15 Hosokawa) or 8:2 (−10 mouthfeel). "Shake" equivalent: wrist snap when leveling mug — removes oversized bubbles, tightens foam lattice.
Draft Beer (Golden 7:3 Foam Ratio) Plating Balance & Oil Cap Sequence (Plating Dynamics & Oil Topping)
Serve on bar counter, not table — foam collapses during walk (+8 Hosokawa for counter serve). Mug handle at 4 o'clock for right-hand grip photo. Foam line exactly at mug rim 70% mark — visible golden liquid band below white cap. Condensation on mug exterior = freshness signal (+4). Never wipe mug — water droplets are intentional presentation.
Draft Beer (Golden 7:3 Foam Ratio) Cost, Margin & Daily Volume Finance (Cost, ROI & Profit Analysis)
Cost ¥80 (keg allocation ¥62, CO₂ ¥8, glass chill ¥10). Price ¥420 → margin ¥340 (425%). Zero prep time — 80–120 pours/day limited only by tap throughput. Best profit-per-second in game. Combo attach rate 45% with spicy ramen. Volume pricing ¥380 still yields 375% margin. Fund shop upgrades fastest via beer-first strategy days 1–5.

Draft Beer (Golden 7:3 Foam Ratio) Common Blunders & Emergency Fixes (Troubleshooting & Common Blunders)
Symptom: Flat beer / no foam (warm glass)
Emergency Fix: Mug must be −8°C for 10min minimum. Warm glass = Hosokawa instant −25.
Symptom: Ratio drifts to 6:4 or 8:2
Emergency Fix: Release main lever at 70% line; reverse push exactly 3s for foam cap. ±2s foam phase = −15 Hosokawa.
Symptom: Foam collapses during table walk
Emergency Fix: Counter serve only — never walk to table. Table serve = −15 Hosokawa; foam dies in transit.
Symptom: Oversized bubbles in foam cap
Emergency Fix: Wrist snap when leveling mug upright — removes oversized bubbles, tightens lattice. Wipe mug = −4 freshness.
