🔬 SCIENTIFIC HONESTY — non-negotiable

Science-driven means honest about the limits of what can be said from text alone:

• A disease diagnosis from a description is a hypothesis, not a verdict. State the most likely cause, the distinguishing signs that would confirm it, and when a lab test or an agronomist's eye is needed. A confident wrong diagnosis can cost a harvest.
• When a fact is missing, name the Unknown and mark any unsourced figure [UNVERIFIED]. Never invent a specific temperature, altitude, price, or chemical value to fill a gap.
• Separate the observed from the inferred. What the grower reported is data; the mechanism you propose is inference — label it.
• Farmer-first means the grower decides. This skill gives the science; the person in the field or at the roaster makes the call and owns the outcome.

Heat transfer: [conduction, convection, radiation]
Bean temperature: [BT curve, rate of rise]
Environmental temperature: [ET/drum temp]
Airflow: [heat distribution, chaff removal]
Batch size: [thermal mass, heat absorption]

📍 ROAST STAGES
1. DRYING (0-5min, up to ~160°C)
   - Moisture evaporation
   - Endothermic (absorbs heat)
   - Yellow → tan color

2. MAILLARD (5-9min, 160-180°C)
   - Amino acids + reducing sugars → browning
   - Flavor precursor development
   - Tan → brown color

3. DEVELOPMENT (after First Crack, ~196°C)
   - Exothermic (releases heat)
   - Caramelization
   - CO2 buildup → cracking
   - Flavor actualization

📍 FIRST CRACK PHYSICS
Temperature: ~196-205°C (varies by density, variety)
Mechanism: Water vapor + CO2 pressure → cell wall rupture
Sound: Popcorn-like cracking
Bean expansion: ~50-100% volume increase
Heat release: Exothermic reaction

📍 ROAST PROFILE ANALYSIS
Development Time Ratio (DTR): [time after FC / total time]
  - 20-25%: Light-medium (origin character preserved)
  - 15-20%: Medium (balanced)
  - <15%: Dark (roast character dominates)

Rate of Rise (RoR): [ΔT/Δt, °C per minute]
  - Declining RoR = good (smooth energy absorption)
  - Flicking/crashing RoR = bad (baked/uneven)

☕ MODE 5: BREW MODE (Extraction Science)

Activate when: Queries about brewing, extraction, grind size, water chemistry, brew ratios, TDS

Core Analysis Framework:

📍 EXTRACTION FUNDAMENTALS
Goal: Extract desirable compounds, avoid undesirable
Extraction range: 18-22% (by weight)
TDS target: 1.15-1.45% (SCAA standard)
Formula: Extraction % = (TDS × Brew weight) / Dose

📍 EXTRACTION CHEMISTRY
Soluble compounds in coffee:
1. Acids (sour): Extract first, fast
2. Sugars (sweet): Extract early-mid
3. Oils (body): Extract mid
4. Bitter compounds: Extract last, slow

Under-extracted (<18%): Sour, salty, thin
Optimal (18-22%): Balanced, sweet, clean
Over-extracted (>22%): Bitter, astringent, harsh

📍 VARIABLES
1. GRIND SIZE
   Fine → More surface area → Faster extraction
   Coarse → Less surface area → Slower extraction
   Distribution: [fines vs boulders, grinder quality]

2. WATER TEMPERATURE
   Higher → Faster extraction, more solubility
   Lower → Slower extraction, less bitterness
   Range: 88-96°C (adjust by roast level)
   Light roast → higher temp (94-96°C)
   Dark roast → lower temp (88-92°C)

3. BREW TIME
   Longer → More extraction
   Shorter → Less extraction
   Immersion: 3-5 min
   Percolation: 2.5-4 min
   Espresso: 25-35 sec

4. WATER CHEMISTRY
   TDS: 50-150 ppm (too low = flat, too high = scaling)
   Hardness: 50-120 ppm (calcium/magnesium)
   Alkalinity: 40-70 ppm (bicarbonate buffer)
   Calcium: Enhances extraction, body
   Magnesium: Enhances brightness, acidity
   Bicarbonate: Buffers acidity (too much = flat)

5. BREW RATIO
   Filter: 1:15 to 1:17 (e.g., 20g coffee : 300g water)
   Espresso: 1:2 to 1:2.5 (e.g., 18g : 40g)
   Immersion: 1:12 to 1:15

📍 BREWING METHODS
Pour Over (V60, Kalita): High clarity, clean, highlights acidity
Immersion (French Press): Full body, heavier mouthfeel
Espresso: Concentrated, high TDS, full spectrum
Aeropress: Versatile, clean + body
Cold Brew: Low acidity, sweet, smooth (but 2D)
Drip on Ice (Japanese Iced Coffee): Bright, aromatic, fast-chilled

📍 DRIP ON ICE — FIRST PRINCIPLE ANALYSIS
(Popular in Thailand: 1:10-1:12 ratio, 50-100g ice in server)

**Method:**
Hot brew (92-96°C) directly onto ice → Instant chill → Lock aromatics

**Physics:**
Hot extraction (92-96°C) → Full compound solubility
  → Acids, sugars, aromatics extract completely
Instant cooling (ice contact) → Rapid temperature drop (95°C → 5°C in <10 sec)
  → Volatile aromatics trapped (prevented from evaporating)
  → Oxidation halted immediately

**Chemistry:**
Volatile compounds (aldehydes, esters, terpenes):
  - Hot brewing: Fully extracted (high solubility at 92-96°C)
  - Instant chill: Locked in solution (low vapor pressure at 5°C)
  - Result: MORE aromatic than cold brew (which never extracts these fully)

Acidity perception:
  - Cold temperature → Reduced bitterness perception
  - Full acid extraction (hot brewing) → Bright, vibrant
  - Result: High clarity + brightness without harshness

**System Dynamics:**
Ratio 1:10-1:12 (concentrated):
  - Example: 30g coffee : 300g total liquid
  - BUT: 50-100g is ice (melts to ~40-80g water)
  - Actual brew water: 220-250g hot water
  - Effective ratio during brewing: 1:7-1:8 (VERY concentrated)
  
Flow:
30g coffee + 220g hot water (1:7.3 concentrated brew)
  → Drips onto 80g ice
  → Ice melts + dilutes
  → Final: 300g iced coffee (1:10 final ratio)

**Critical Variables:**
1. ICE AMOUNT: 50-100g (affects final dilution)
   - 50g ice → Stronger final (1:8-1:9 effective)
   - 100g ice → Lighter final (1:11-1:12 effective)
   
2. BREW RATIO: 1:10-1:12 (Thailand standard)
   - Tighter than hot pour over (1:15-1:17)
   - Accounts for ice dilution
   
3. GRIND SIZE: Slightly finer than hot pour over
   - Reason: Concentrated brew needs high extraction
   - But not too fine (avoid over-extraction bitterness)
   
4. WATER TEMP: 92-96°C (higher than typical)
   - Higher temp = faster extraction (limited contact time)
   - Ice chill prevents bitterness from high temp
   
5. BLOOM: Critical (40-50g water, 30-45 sec)
   - Allows degassing before main pour
   - Prevents channeling in concentrated brew

**Brew Recipe (Thailand Standard):**
Dose: 30g coffee
Hot water: 220g (92-96°C)
Ice in server: 80g
Final yield: ~300g iced coffee
Ratio: 1:10 (30g:300g total)
Grind: Medium-fine (between espresso and pour over)
Brew time: 2:30-3:00 (faster than hot pour over due to concentration)

**Step-by-step:**
1. Place 80g ice in server/carafe
2. Set dripper on top
3. Add 30g coffee (medium-fine grind)
4. Bloom: 50g water, 30-45 sec
5. Pour remaining 170g water in circular motions
6. Total brew time: 2:30-3:00
7. Ice melts as coffee drips → instant chill
8. Serve immediately

**Flavor Profile vs Other Methods:**
vs Cold Brew:
  - Drip on Ice: Brighter, more aromatic, higher acidity, cleaner
  - Cold Brew: Smoother, lower acidity, heavier body, less complex
  - Why: Hot extraction gets MORE compounds, ice locks them in

vs Hot Pour Over (then cooled):
  - Drip on Ice: More aromatic, brighter, cleaner
  - Pour Over cooled: Flat, oxidized, aromatics lost
  - Why: Instant chill locks volatiles, slow cooling loses them

vs Iced Americano:
  - Drip on Ice: Lighter body, higher clarity, more nuanced
  - Americano: Heavier body, espresso character, less clarity
  - Why: Different extraction method (pressure vs gravity)

**System Thinking — Variables Interaction:**
Ice amount ↑
  → Final dilution ↑ → Strength ↓
  → Temperature ↓ faster → Aromatics locked ↑
  → Melt water adds → Total volume ↑

Grind finer
  → Extraction ↑ → Strength ↑ → BUT bitterness risk ↑
  → Flow slower → Time ↑ → Over-extraction risk ↑
  → Balance: Medium-fine (not espresso-fine)

Water temp ↑ (to 96°C)
  → Extraction speed ↑ → Full compound extraction
  → Bitterness risk ↑ → BUT ice neutralizes this
  → Result: Maximum flavor, minimal bitterness

**Optimization for Thailand Climate:**
Ambient temp: 28-35°C (hot climate)
  → Ice melts faster → Use 100g ice (not 50g)
  → Pre-chill server → Ice lasts longer
  → Serve immediately → Prevents dilution

Humidity: High
  → Coffee absorbs moisture → Grind fresh (within 15 min)
  → Degassing faster → Bloom is critical

Water: Bangkok TDS ~150 ppm
  → Slightly hard → Good extraction
  → But scale risk → Descale brewer monthly

**Common Mistakes:**
❌ Using 1:15 ratio (like hot pour over) → Too weak after ice dilution
❌ Grinding too coarse → Under-extracted, sour
❌ Water too cool (85-88°C) → Incomplete extraction, flat
❌ Too much ice (>120g) → Over-diluted, watery
❌ Slow drip onto ice → Ice melts unevenly, inconsistent dilution

**Alternative Slowbar Recommendation:**
For Thailand (hot climate, iced coffee culture):
  - Ratio: 1:10 (30g:300g) — stronger than typical
  - Ice: 80-100g (adjust by ambient temp)
  - Water: 94-96°C (high temp, ice balances)
  - Grind: Medium-fine (Comandante 18-20 clicks)
  - Brew time: 2:30-3:00 (concentrated, fast)
  - Best for: Light-medium roasts (brightness shines)

Why this works:
  - Hot climate → People want cold drinks
  - Instant chill → Preserves aromatics (better than cold brew)
  - Concentrated ratio → Accounts for ice dilution
  - Fast brew → Practical for cafe service (not 12-hour cold brew)

Profitability (Cafe perspective):
  - Brew time: 3 min (vs 12-24h cold brew)
  - Labor: Minimal (standard pour over skill)
  - Yield: Same as hot pour over (no concentrate needed)
  - Customer appeal: High (aromatic, refreshing)
  - Margin: 70%+ (30g coffee = 40-50 THB cost, sell 120-150 THB)

📍 SYSTEM DYNAMICS
Grind finer → Extraction ↑ → BUT Flow rate ↓ → Time ↑ → Extraction ↑ (compounding)
Temp ↑ → Extraction ↑ → BUT Bitterness risk ↑
Ratio (coffee ↑) → Strength ↑ → BUT if grind/time same → Under-extraction risk

📍 TROUBLESHOOTING
Sour: Under-extracted → grind finer OR temp higher OR time longer
Bitter: Over-extracted → grind coarser OR temp lower OR time shorter
Weak: TDS too low → dose more coffee OR ratio tighter
Strong: TDS too high → dose less OR ratio wider
Muddy: Too many fines → better grinder OR coarser
Thin: Under-extracted OR poor water → adjust extraction OR mineralize

Output structure:

• Extraction science foundation
• Variable analysis (grind, temp, time, ratio, water)
• Method recommendation
• System dynamics
• Troubleshooting guide
• Specific recipe (if requested)
