How to Make French Press Coffee: Perfect Recipe & Ratio Guide
Exact Ratios for Specified French Press Sizes (1:18 Coffee to Water Ratio)
Knowing how to make French press coffee properly takes your morning cup from bitter to brilliant. Use a 1:18 ratio (grams of coffee to ml of water) for balanced French press coffee, as recommended for various press sizes. This yields approximately 19-20g coffee per 350ml water, scaling linearly.
| French Press Size | Water (ml) | Coffee (g) |
|-------------------|------------|------------|
| 350ml | 350 | 19g |
| 600ml | 600 | 33g |
| 1000ml | 1000 | 56g |
Step-by-Step Brewing Method (James Hoffmann-Inspired)
1. Boil water to 92-96°C (Specialty Coffee Association recommendation for optimal extraction in immersion methods like French press). Off-boil (around 205-210°F or 96°C) works well; let it cool slightly if needed.
2. Grind coffee coarsely—like kosher salt or sea salt granules (even, not fine, to avoid sludge and over-extraction).
3. Add grounds to French press (e.g., 19g for 350ml).
4. Pour all water over grounds in a circular motion to wet evenly; stir gently to break crust.
5. Steep for 4 minutes total (standard SCA-aligned method: bloom 30-60s, then steep to 4min before pressing). James Hoffmann uses 10 minutes total (5min initial steep, stir/scoop crust, 5min more) for cleaner cup with less sediment.
6. Press plunger slowly (20-30s); if resistance is high, grind coarser next time.
7. Pour immediately into cups; do not let sit in press.
Pre-heat press with hot water first, discard, for better temperature stability.
Common Mistakes
- Wrong grind: Too fine causes bitterness/sludge; too coarse under-extracts (weak/tart).
- Incorrect temperature: Below 92°C under-extracts; above 96°C over-extracts bitterness.
- Over-steeping: Leads to over-extraction; press and pour at exact time.
- No stirring/bloom: Uneven extraction; always agitate initially.
- Pressing too fast/hard: Releases fines, making muddy coffee.
- Using volume (tbsp) instead of grams: Inaccurate due to grind/roast density; weigh for precision.

Frequently Asked Questions
What is the perfect French press recipe?
Use a 1:15 ratio (1g coffee to 15ml water). For a 600ml French press: 40g coarse ground coffee + 600ml water at 93 degrees C. Steep 4 minutes. Press slowly. The Specialty Coffee Association recommends water temperature between 92-96 degrees C for optimal extraction.
How long should French press coffee steep?
4 minutes is the standard recommended by SCA and most specialty coffee professionals. Under 3 minutes results in sour, under-extracted coffee. Over 5 minutes results in bitter, over-extracted coffee. Set a timer for consistency.
Do I need a special kettle?
No. Any kettle works. Boil water, then let it sit for 30-60 seconds to drop from 100 degrees C to approximately 93 degrees C. If you have a thermometer or temperature-controlled kettle, aim for 93 degrees C directly.
