To use a French press: add coarsely ground coffee at a 1:15 ratio (1g coffee per 15g water), pour hot water at 200°F (93°C), stir, steep for 4 minutes, then press the plunger down slowly and pour immediately.
That’s the core process. The rest of this guide covers why each step matters, how to dial in your ratio and grind, and how to fix the most common French press problems.
What You Need
- French press (any size — 12 oz, 17 oz, or 34 oz are common)
- Coarsely ground coffee (or a burr grinder + whole beans)
- Water just off boil (195–205°F / 90–96°C)
- Kitchen scale (strongly recommended for consistent results)
- Stirring spoon (wood, bamboo, or silicone — not metal, which can crack glass)
- Timer
French Press Ratio
Standard ratio: 1:15 — 1g of coffee for every 15g of water.
| French Press Size | Coffee | Water |
|---|---|---|
| 12 oz (350ml) | 23g | 350g |
| 17 oz (500ml) | 33g | 500g |
| 34 oz (1L) | 67g | 1000g |
Adjust to taste:
- For stronger coffee: use a 1:12 or 1:13 ratio
- For lighter coffee: use a 1:16 or 1:17 ratio
See our French press ratio guide for a complete ratio table including tablespoon measurements if you don’t have a scale.
Step-by-Step Instructions
Step 1: Preheat your French press
Pour hot water into the empty French press to preheat the glass. This prevents your brewing temperature from dropping when you add coffee. Swirl and discard the preheating water.
Step 2: Measure and grind coffee
Measure your coffee by weight. Grind to a coarse setting — similar to coarse sea salt or breadcrumbs. Coarse grind is critical. Fine grinds slip through the metal filter, make your coffee gritty, and cause over-extraction (bitter coffee).
Step 3: Add coffee and start your timer
Add the ground coffee to the press. Start your timer.
Step 4: Pour hot water (bloom)
Pour a small amount of hot water (about 2x the weight of the coffee) over the grounds to wet them evenly. This is the bloom — it allows CO₂ to escape from the coffee. Wait 30–45 seconds.
If you’re in a hurry, you can skip the bloom. It improves flavor consistency but isn’t strictly required.
Step 5: Fill with water
Pour the rest of your hot water in a slow, even spiral. Ensure all grounds are saturated. Place the lid on the press (plunger pulled up to the top) to retain heat.
Step 6: Steep for 4 minutes
Wait 4 minutes. This is the standard steep time for a 1:15 ratio at 200°F. During this time, do not press, stir, or agitate.
Steep time adjustment:
- Stronger, more full-bodied: steep 4:30–5:00
- Lighter, cleaner: steep 3:30
Step 7: Stir before pressing (optional)
Some brewers give the crust (grounds floating on top) a gentle stir at the 4-minute mark before pressing. This slightly improves extraction evenness. Others skip this step.
Step 8: Press slowly
Press the plunger down with steady, even pressure over 20–30 seconds. Do not press hard or fast. Fast pressing forces grounds through the filter and makes coffee gritty. If there’s strong resistance, your grind may be too fine.
Stop pressing when the plunger is about an inch above the grounds — do not compress the grounds completely at the bottom.
Step 9: Pour immediately
Pour all the coffee out immediately after pressing. Do not let coffee sit in the French press after pressing — it will continue to extract and become bitter. If you’re not drinking it all at once, pour the remainder into a thermal carafe or second vessel.
Grind Size: The Most Important Variable
The biggest mistake people make with French press is using the wrong grind size.
Correct grind: Coarse — like coarse sea salt or rough bread crumbs.
| Grind Size | Result |
|---|---|
| Too fine (espresso grind) | Gritty, muddy, bitter, hard to press |
| Slightly too fine | Slightly bitter, harder to press |
| Correct (coarse) | Clean, full-bodied, easy to press |
| Too coarse | Weak, sour, under-extracted |
If you’re using pre-ground coffee, look for bags labeled “French press” or “coarse grind.” Most pre-ground coffee sold as “French press” is ground correctly.
If you’re grinding your own: start at the coarsest setting on your grinder and work your way finer until you dial in the taste you want.
Water Temperature
Target: 195–205°F (90–96°C).
The simplest approach: bring water to a full boil, then let it sit for 30–45 seconds before pouring. This naturally brings temperature from 212°F (100°C) down to the target range.
Cold water won’t extract properly. Boiling water can over-extract very light roasts.
Dark roasts can handle closer to boiling (205°F). Light roasts benefit from slightly lower temperature (195–200°F) to avoid bitterness.
French Press Steep Times
| Strength Preference | Grind | Ratio | Time |
|---|---|---|---|
| Light/delicate | Coarse | 1:16 | 3:30 |
| Standard | Coarse | 1:15 | 4:00 |
| Strong | Coarse | 1:13 | 4:30 |
| Very strong | Coarse | 1:12 | 5:00 |
Adjust one variable at a time when dialing in. Grind size has the most impact on clarity; ratio has the most impact on strength; time fine-tunes extraction.
Cleaning Your French Press
After every use:
- Discard grounds (compost or trash — do not pour grounds down the drain)
- Rinse the beaker and plunger with warm water
- Disassemble the filter assembly occasionally (unscrew the base of the plunger) to clean the filter screens
Deep clean: Disassemble the plunger completely. Soak the metal filter screens in warm soapy water. Use a soft brush to clean all parts. Rinse thoroughly and dry before reassembly.
Coffee oils build up on glass and metal and turn rancid. Clean your French press daily for best flavor.
Common French Press Problems
Problem: Coffee is gritty / muddy
- Grind is too fine — switch to a coarser setting
- Filter screens may be damaged or loose — check the plunger assembly
Problem: Coffee is bitter
- Grind too fine, or steep time too long
- Water temperature too high for light roast
- Left coffee sitting in the press after pressing — always pour immediately
Problem: Coffee is weak / sour
- Grind too coarse
- Steep time too short
- Water temperature too low
- Too little coffee — check your ratio
Problem: Hard to press / strong resistance
- Grind is too fine — use a coarser grind
- Pressing too quickly — slow down
Problem: Coffee doesn’t stay hot
- Preheat the French press before brewing
- Use a double-walled insulated French press (Frieling, Fellow Clara)
- Pour into a thermal carafe after pressing
French Press vs Other Brewing Methods
| Method | Grind | Ratio | Time | Body |
|---|---|---|---|---|
| French press | Coarse | 1:15 | 4 min | Full, rich |
| Pour over / V60 | Medium-fine | 1:16 | 3–4 min | Clean, bright |
| AeroPress | Medium | 1:12–1:15 | 1–2 min | Concentrated, versatile |
| Drip machine | Medium | 1:15–1:17 | 5–8 min | Medium body |
| Moka pot | Fine-medium | N/A | 5 min | Very strong, espresso-like |

The Best French Press Coffees
Dark roast: The full-immersion brewing style of French press extracts the most from dark roasts — you’ll taste rich chocolate, caramel, and low-acid body. Ideal for people who like bold coffee.
Medium roast: Produces a balanced cup with fruit notes intact. The French press’s full immersion style amplifies body more than pour-over.
Light roast: Works well at slightly lower temperature (195°F) and shorter steep time (3:30). The coarser grind lets more delicate flavors through without bitterness.
Arabica vs robusta: Both work in French press. Arabica is sweeter and more nuanced. Robusta is more bitter, higher caffeine, and produces a thicker, more crema-like body.
Frequently Asked Questions
How long do you steep French press coffee? Standard steep time is 4 minutes at a 1:15 ratio and 200°F water. Shorter (3:30) for a lighter cup, longer (4:30–5:00) for a stronger cup.
How much coffee do I put in a French press? Use a 1:15 ratio — 1g of coffee per 15g of water. For a 17oz (500ml) French press, that’s about 33g of coffee (roughly 5 tablespoons).
Can you use regular ground coffee in a French press? Yes, but results vary. Most “regular” pre-ground coffee is ground too fine for French press (it’s usually medium grind for drip machines). Look for coffee specifically ground for French press (coarse grind), or grind your own.
Why is my French press coffee bitter? Usually caused by too-fine a grind, too long a steep, or leaving coffee in the press after pressing (it keeps extracting). Try coarser grind, shorter steep, and pour immediately after pressing.
Should you press French press all the way down? Press until about 1 inch above the grounds — don’t force the grounds all the way to the bottom. Over-pressing can force sediment through the filter.
Can you make cold brew in a French press? Yes. Add coarsely ground coffee at a 1:8 ratio (coffee to cold water), stir, and steep in the refrigerator for 12–24 hours. Then press slowly and pour. This makes a smooth, low-acid cold brew concentrate. See our cold brew ratio guide and cold brew recipe for full instructions.
