PID Temperature Settings for Different Beans
Temperature's interaction with roast level, origin, and processing isn't clearly mapped. Here's how to adjust your PID for optimal extraction.
⚡ Quick Answer
Start at 200°F (93°C) as your baseline, then adjust based on roast level and origin. Light roasts and high-altitude dense beans need 203-205°F to extract properly. Dark roasts and low-grown Brazilian/Colombian coffees do better at 198-200°F to prevent bitterness. Natural/dry-processed coffees often prefer slightly lower temps (198-201°F) than washed coffees (200-203°F). Adjust in 2-3°F increments and taste—temperature is a powerful but underutilized variable.
🎯 Key Takeaway: Temperature is an independent variable from grind. Use it to fine-tune extraction when grind is already dialed but taste isn't quite right.
Temperature by Coffee Characteristic
By Roast Level
Light Roast
203-205°F
Needs heat to penetrate dense structure
Medium ⭐
200-202°F
Standard baseline
Dark Roast
198-200°F
Prevent burning, bitterness
By Processing Method
Washed/ Wet Processed
Cleaner, brighter profile. Slightly higher temps (200-203°F) help extract clarity and acidity.
Natural/ Dry Processed
Fruiter, heavier body. Lower temps (198-201°F) prevent over-extraction of ferment notes.
By Origin/Altitude
When and How to Adjust
Temperature Adjustment Protocol
- 1. Dial grind first: Get extraction time in 25-30 second range at your baseline 200°F
- 2. Taste evaluation: If timing is right but taste is off, adjust temperature
- 3. Sour/under-extracted: Increase 2°F and test again
- 4. Bitter/harsh: Decrease 2°F and test again
- 5. Fine-tune: Adjust in 1-2°F increments until sweet spot found
Note: Allow machine 10-15 minutes to stabilize at new temperature before testing.
