immersion method
French press
Coarse coffee grounds steep fully immersed in hot water, then a metal mesh plunger separates the grounds from the brewed coffee, retaining oils and some fine sediment.
- Coffee-to-water ratio
- 55–70 g per litre (typically 63)
- Grind
- Coarse, similar to sea salt or breadcrumbs.
- Water temperature
- 92-96 celsius (typically 94)°C
- Contact time
- 240-300 seconds (typically 240)
- Skill level
- beginner
Descriptive grind labels like this are illustrative starting points, not precise measurements — the same label can mean different particle sizes on different grinders. See the grind size guide for how to dial this in on your own equipment.
Expected flavour profile
Produces a full-bodied, heavier cup with more perceived texture and some fine sediment, since the metal mesh plunger doesn't remove oils or the smallest particles the way a paper filter does. Flavour tends to read as rounder and less bright than paper-filtered methods.
Equipment
Common problems
- Gritty sediment in the cup
- Coffee tastes flat or muddy
- Coffee becomes bitter if left to sit
Grind coarser to reduce sediment; pour off or drink promptly once plunged to avoid continued steeping.

Change the taste
Tastes sour
(French press)The brew tastes sour or acidic rather than balanced.
Try the first step below on its own, taste, then move to the next one only if needed.
| Change | Try | Why | Watch for |
|---|---|---|---|
| FirstGrind size | Decrease: a small step finer, while staying in the coarse-to-medium range | Usually increases extraction. | — |
| Brew or steep time | Increase: steep 30-60 seconds longer | More contact time usually increases extraction. | — |
| Water temperature | Increase: use water closer to just off the boil | Hotter water extracts more quickly. | — |
When to reset: Return to your usual steep time and grind before a second change.
Want to know why? Extraction, Contact time
Tastes weak
(French press)The brew tastes thin in strength.
Try the first step below on its own, taste, then move to the next one only if needed.
| Change | Try | Why | Watch for |
|---|---|---|---|
| FirstDose | Increase: add coffee to reach a standard ratio | Raises strength directly. | — |
| Grind size | Decrease: a small step finer | Can add body via slightly higher extraction, a secondary lever. | — |
| Brew or steep time | Increase: steep a little longer | More contact time can help if the grind and dose are already correct. | — |
When to reset: Adjust dose first via the ratio calculator before changing grind or time.
Want to know why? Strength (intensity), Extraction
Tastes harsh or dry
(French press)The brew tastes bitter or harsh rather than balanced.
Try the first step below on its own, taste, then move to the next one only if needed.
| Change | Try | Why | Watch for |
|---|---|---|---|
| FirstGrind size | Increase: a small step coarser | Usually reduces extraction. | — |
| Brew or steep time | Decrease: steep 30-60 seconds less | Less contact time usually reduces extraction. | — |
| Water temperature | Decrease: let the water cool slightly off the boil | Slightly cooler water extracts more slowly, softening bitterness. | — |
| Plunge / decant | Check / reset: decant into another vessel immediately after plunging | Coffee left in contact with grounds after plunging keeps extracting and can turn bitter. | — |
When to reset: Decant promptly and re-taste before changing grind or time.
Tastes muddy or silty
(French press)The cup has a gritty, silty texture and visible sediment.
Try the first step below on its own, taste, then move to the next one only if needed.
| Change | Try | Why | Watch for |
|---|---|---|---|
| FirstGrind size | Increase: a small step coarser | A grinder producing too many fines at a fine setting is the most common cause. | — |
| Agitation | Decrease: stir gently once, rather than repeatedly | Less agitation disturbs fewer fines into suspension. | — |
| Plunge / decant | Decrease: plunge slowly and stop before the plunger meets resistance | A slow plunge disturbs the crust and fines less than a fast one. | — |
When to reset: Let the coffee settle for a minute before pouring, and check your grinder for excess fines.
Tastes too strong
(French press)The brew is otherwise balanced but too intense.
Try the first step below on its own, taste, then move to the next one only if needed.
| Change | Try | Why | Watch for |
|---|---|---|---|
| FirstDose | Decrease: use less coffee next time | Directly lowers strength. | — |
| Water amount | Increase: add hot water after brewing | Dilutes strength without changing extraction. | — |
Prefer diluting or reducing dose over shortening steep time, which changes extraction rather than strength.
When to reset: Note the dose or dilution you settle on as your new default.
Cleaning & maintenance
Disassemble the plunger and rinse all mesh layers; grounds can clog the filter over time if not cleaned thoroughly.
Replace the mesh filter or gasket if it no longer seals against the glass or metal carafe.

Techniques for this method
The individual skills this method uses, each with its own adjustments and failure modes.
- Frothing milk without a steam wandGet a usable milk foam using an electric frother, a whisk, a French press or a jar, and know what each can and cannot produce.
- Adjusting grind sizeMove the grind in the right direction by a useful amount, and know what to expect from the change.
- Comparing two coffees side by sideTrain perception using difference, which is far easier to notice than any absolute quality.
