The Ultimate Guide to Water Temperature in Pour-Over Coffee
Master the art of water temperature for pour-over coffee. Learn optimal brewing temperatures, how they affect extraction, and get precise recommendations for different roast levels.
Why Water Temperature Matters in Pour-Over Coffee
Water temperature is one of the most critical variables in coffee extraction. It affects how quickly and efficiently the flavour compounds are extracted from your coffee grounds, ultimately determining the taste, aroma, and overall quality of your brew.
The Ideal Temperature Range
The Specialty Coffee Association (SCA) recommends a water temperature between 92°C to 96°C (198°F to 205°F) for optimal extraction. However, this range can be adjusted based on your specific needs and preferences.
Temperature Guidelines by Roast Level
- Light Roasts: 94-96°C (201-205°F) - Higher temperatures help extract the dense cellular structure of light roasts
- Medium Roasts: 92-94°C (198-201°F) - Balanced temperature for optimal extraction
- Dark Roasts: 90-92°C (194-198°F) - Lower temperatures prevent over-extraction and bitter notes
How Temperature Affects Extraction
Water temperature directly influences the rate and efficiency of extraction:
- Higher temperatures increase extraction rate and solubility
- Lower temperatures slow down extraction and can lead to under-extraction
- Inconsistent temperatures can result in uneven extraction
Under-extraction (Water Too Cool)
Signs include sour, grassy, or lacking sweetness. Solution: Ensure your water is heated to the proper temperature and consider pre-heating your brewing equipment.
Over-extraction (Water Too Hot)
Results in bitter, harsh, or astringent flavours. Solution: Let your water cool slightly after boiling or adjust your temperature control if using a variable temperature kettle.
Equipment Recommendations
To maintain consistent water temperature throughout your brew:
Best Practices for Temperature Control
- Always start with fresh, filtered water
- Pre-heat your brewer and server
- Maintain consistent temperature throughout the brew
- Adjust based on roast level and desired outcome
- Consider altitude adjustments (water boils at lower temperatures at higher altitudes)
Conclusion
Mastering water temperature is crucial for consistently great pour-over coffee. While the SCA guidelines provide a solid starting point, don't be afraid to experiment within these ranges to find what works best for your specific beans and taste preferences.
