Simulation Engine
Physics-based dilution modeling. Every cocktail simulated in 5-second time steps against real ice profiles, vessel thermal properties, and ambient conditions.

How It Works
The simulation engine models dilution as a continuous physical process, not a simple percentage lookup. At each 5-second time step, the engine calculates:
- Ice surface area and melt rate based on ice profile geometry
- Temperature-dependent melt acceleration (ambient heat transfer)
- Agitation multiplier effect on exposed ice surface
- Vessel thermal conductivity contribution
- Freezing point depression from alcohol and sugar content
The result is a dilution curve over time — not a single number — showing exactly how a cocktail evolves from shake to last sip.
Agitation Multipliers
Each technique applies a multiplier to the base melt rate. Higher agitation exposes more ice surface area, accelerating dilution.
| Technique | Multiplier | Default Time | Description |
|---|---|---|---|
| Stirred | 1.0x | 30s | Gentle, controlled dilution. Spirit-forward cocktails. |
| Shaken | 2.8x | 12s | Standard shake. Sours, daiquiris, margaritas. |
| Thrown | 1.4x | 8s | Poured between vessels. Aeration without over-dilution. |
| Built | 0.3x | 0s | No active mixing. Highballs, fizzes after build. |
| Swizzled | 1.6x | 15s | Swizzle stick between palms. Tiki and crushed ice drinks. |
| Dry Shaken | 0.0x | 15s | No ice — emulsification only. Egg white foams. |
| Whip Shaken | 3.2x | 8s | Small ice, hard shake. Maximum aeration and chill. |
| Blended | 4.0x | 30s | Full mechanical integration. Frozen cocktails. |
Target Dilution Ranges
Each cocktail category has a calibrated dilution target. Recipes are scored against these ranges to determine if they're within acceptable parameters.
| Category | Target Range | Confidence | Examples |
|---|---|---|---|
| Spirit-Forward | 18–25% | Full | Old Fashioned, Negroni, Manhattan |
| Sour | 20–28% | Full | Daiquiri, Whiskey Sour, Margarita |
| Highball | 20–35% | Provisional | Gin & Tonic, Paloma, Highball |
| Fizz | 15–22% | Provisional | Gin Fizz, Ramos, Tom Collins |
| Tiki | 22–32% | Provisional | Mai Tai, Zombie, Painkiller |
| Frozen | 25–40% | Provisional | Frozen Daiquiri, Pina Colada |
| Punch | 15–25% | Full | Planter's Punch, Fish House |
| Hot | 18–32% | Full | Hot Toddy, Irish Coffee |
| Flip | 15–22% | Full | Brandy Flip, Eggnog |
| Martini | 18–25% | Full | Martini, Gibson, Vesper |
Qualification Scoring
These two scenario-run scores roll up into the Service Resilience band shown on every recipe card.
Master Score
Primary quality metric. Measures how well a recipe hits its category's dilution target under standard conditions (72°F, fresh ice, chilled glass, 12s shake). Score range: 0–100. Passing threshold: 70.
Forgiveness Score
Measures resilience across chaos scenarios. A cocktail with a high master score but low forgiveness score works perfectly in ideal conditions but falls apart under stress. Score range: 0–100. High forgiveness (>80) earns the “bulletproof” tag.
Confidence Flags
Full Confidence
Categories with well-established dilution science and extensive calibration data. Spirit-forward, sour, punch, hot, flip, martini.
Provisional
Categories where dilution targets are based on limited data or complex multi-phase processes. Highball, fizz, tiki, frozen. Targets may shift as calibration data grows.
