## Brewing Suites & Supported Extraction Protocols

### 1. Espresso Dial-In Lab
- **Physical Basket Clamping**: Tailored extraction boundaries for 51mm (13.5g–14.5g limit to prevent shower bolt channeling), 54mm (16g–17.5g), and 58mm commercial groups (18g–20g).
- **Sensory Diagnostics**: Systematic resolution for sour under-extraction (stretch yield to 1:2.5, increase temp) vs. bitter over-extraction (tighten yield to 1:1.5–1:1.8, coarsen grind).
- **Kitchen Scale Fallback**: Translates doses into level measuring tablespoons (~5.3g per level tbsp) and volume-based extraction cutoffs.

### 2. Auto-Drip & Batch Brewers (e.g., Mr. Coffee, Moccamaster)
- **Gross vs. Retained Water Math**: Explicit separation between reservoir volume and drinkable cup yield (accounting for 2.0x dry coffee absorption factor).
- **Carafe Line Calibration**: Direct translation of standard cup markings (5 fl oz / 148ml) to required dry coffee tablespoons and reservoir fill levels.

### 3. Cone & Pour-Over (V60, Kalita Wave, Origami)
- **Staged Pouring Sequences**: 2x–3x dry dose bloom saturation (45s degassing) followed by controlled concentric pulses to manage bed agitation and fines migration.
- **Drawdown Control**: Flow calibration to balance sweet dissolution against channel bypass.

### 4. French Press & Full Immersion
- **Equilibrium Extraction**: Extended steep parameters (4–5 minutes) ensuring uniform solubilization without astringency.
- **Sediment & Crust Protocol**: Crust break and surface skimming technique to minimize cup silt while preserving natural lipids and body.

### 5. Authentic Turkish Coffee & Cup Diagnostics (Cezve & Fal)
- **Milling & Thermal Control**: Flour-fine milling (<75µm) at a 1:10 ratio with a 2:15–2:45 min gentle stovetop thermal rise. Foam crowned at rim, never boiled.
- **Grounds Settling**: Mandated 90-second cup resting window for sediment consolidation.
- **Traditional Cup Reading**: Computer-vision and AI spatial interpretation of dried grounds across 3 cup quadrants (Rim/Near-term, Mid-slopes/Momentum, Basin/Core) linked to 32 Anatolian proverbs.
