The French press process can be summed up in as little as saying: boil water, pour over coffee grounds, wait six minutes, then press! However, since some systems may be a little more complex, Koffee Kult recommends sticking to the following steps when using your French press version.
What You'll Need
Equipment:
✅ French press (any size - 3 cup, 8 cup, or 12 cup)
✅ Kettle for boiling water
✅ Coffee grinder (burr grinder preferred)
✅ Digital scale (optional but recommended)
✅ Timer (your phone works!)
✅ Spoon or stirrer
Ingredients:
☕ 20g coarse ground coffee (for 12oz/350ml water)
? Hot water at 195-205°F (90-96°C)
? Ratio: 1:15-1:17 (coffee to water)
Step-by-Step French Press Instructions
Step 1: Boil Your Water ?️
Bring water to a boil, then let it cool for about 30 seconds.
Why this temperature matters:
- 195-205°F (90-96°C) is the ideal range
- Too hot = bitter, burnt taste
- Too cold = sour, under-extracted coffee
- After boiling, wait 30 seconds = approximately 200°F
Pro tip: While water is boiling, prepare your French press and grind your coffee!
Step 2: Weigh Out Coffee ⚖️
Weigh out 20 grams of 100% Arabica Medium Roast coffee beans, ground coarsely.
Coffee-to-water ratios:
| Coffee | Water | Ratio | Strength |
|---|---|---|---|
| 15g | 250ml (8oz) | 1:17 | Lighter |
| 20g | 340ml (12oz) | 1:17 | Standard |
| 30g | 500ml (17oz) | 1:17 | Standard |
| 20g | 300ml (10oz) | 1:15 | Stronger |
Grind size is critical!
- Coarse grind = like breadcrumbs or sea salt
- Too fine = bitter, over-extracted, muddy coffee
- Too coarse = weak, under-extracted coffee
Pro tip: If you don't have a scale, use roughly 2 tablespoons of coffee per 6oz of water.
Step 3: Preheat Your French Press ?
Fill your French press with the boiling water (cooled 30 seconds) and press the plunger all the way down to the bottom and swirl.
Why preheat?
- ✅ Warms up the glass so coffee stays hot longer
- ✅ Helps maintain consistent brewing temperature
- ✅ Prevents thermal shock to glass French press
After 10 seconds of swirling the water, pour it out.
Important: Discard ALL the preheating water before adding coffee!
Step 4: Add Coffee & Bloom ☕
This part is called the "bloom." Pour the 20 grams of ground coffee into the French press and pour your five ounces of water on top, making sure that you are distributing the water evenly and saturating all of the coffee grounds.
The bloom process:
- Add your coarse ground coffee to the empty French press
- Start your timer
- Pour about 1/3 of your water over the grounds
- Stir gently to ensure all grounds are saturated
- Wait 30-45 seconds - you'll see bubbling and foaming
Why bloom matters:
- Fresh coffee releases CO₂ gas
- Blooming allows gas to escape
- Prepares grounds for even extraction
- Improves overall flavor
Pro tip: Fresh Koffee Kult coffee will bloom vigorously - a sign of quality!
Step 5: Break the Crust ⏰
After 30-45 seconds has passed, slowly stir in a circular motion for five to ten seconds in order to break up the crust-like layer that formed during the bloom process.
What's "the crust"?
- Coffee grounds float to the top during bloom
- Forms a thick layer on the surface
- Needs to be broken up for even extraction
How to break it properly:
- Use a spoon or wooden stirrer
- Stir gently in circular motions
- Don't over-stir - just break up the crust
- 5-10 seconds is plenty
Step 6: Add Remaining Water ?
After everything has been mixed evenly with the first five ounces of water, pour the remaining five ounces of water on top, place the lid on your French press, and make sure that the plunger is all the way at the top.
Pouring technique:
- Pour slowly and steadily
- Aim for the center, letting water distribute naturally
- Don't pour too aggressively (causes agitation)
- Fill to desired level (leave room for plunger)
Total water for 20g coffee: Approximately 10oz (300ml) total
Step 7: Steep for 4 Minutes ⏱️
Let the coffee steep for another four minutes.
Why 4 minutes?
- Perfect extraction time for coarse grind
- Not too short (under-extracted/sour)
- Not too long (over-extracted/bitter)
Timing variations:
- 3 minutes: Lighter, brighter flavor
- 4 minutes: Standard, balanced (recommended)
- 5 minutes: Bolder, fuller body
- 6+ minutes: Risk of over-extraction and bitterness
What to do while waiting:
- Prepare your mug
- Get milk/cream ready (if using)
- Clean up grounds and equipment
- Just relax!
Step 8: Press the Plunger ?
Very slowly and carefully press the plunger all the way down to filter the grounds from the coffee.
Proper pressing technique:
- Press slowly - take 15-20 seconds to fully press
- Apply steady pressure - not too hard!
- If you feel resistance - stop, lift plunger slightly, then continue
- Press all the way down to the bottom
Why press slowly?
- ✅ Prevents grounds from escaping filter
- ✅ Avoids agitation that causes bitterness
- ✅ Creates cleaner cup with less sediment
- ✅ Safer - less likely to splash hot coffee
Pro tip: If pressing is very difficult, your grind is too fine!
Step 9: Pour and Enjoy Immediately! ?
Don't let it sit too long in the French press or your coffee will turn bitter, instead, immediately pour your coffee and enjoy!
Critical: Pour out ALL the coffee immediately after pressing!
Why this matters:
- Coffee continues extracting while sitting in French press
- Gets increasingly bitter the longer it sits
- Even with plunger pressed, grounds are still in contact with coffee
Serving tips:
- Pour into a thermal carafe if not drinking immediately
- Serve in preheated mugs for best temperature
- Add milk/cream/sugar to taste
- Enjoy while hot!

- Glass French press (less insulation)
Solutions:
- ✅ Always preheat with hot water
- ✅ Preheat your mug too
- ✅ Use insulated/stainless steel French press
- ✅ Make less coffee and brew fresh when needed
Cleaning Your French Press
After Each Use:
- Discard grounds - compost them!
- Disassemble plunger - unscrew the filter assembly
- Rinse thoroughly - remove all coffee residue
- Wash with soap - mild dish soap is fine
- Rinse again - ensure no soap remains
- Air dry completely before reassembling
Deep Cleaning (Weekly):
- Completely disassemble all plunger parts
- Soak in hot, soapy water for 10 minutes
- Scrub filter screens with brush to remove oils
- Check for damage - replace worn parts
- Rinse thoroughly and dry
Pro tip: Coffee oils build up on the mesh screens and make coffee taste rancid. Clean regularly!
Monthly Maintenance:
- Inspect for cracks (especially glass carafes)
- Check filter screens for holes or warping
- Replace worn parts as needed
- Deep clean with baking soda paste if needed
