Brewing Guide to Cafetieres / French Press
Cafetiere, or french press, coffee makers are a great way to make coffee as the brew they produce is rich and full bodied. They are simple to use and are fairly easy to clean afterwards.
Many coffee lovers swear that cafetieres are the best coffee makers, as they let the coffee do the talking. All the delicate flavours in the oils are preserved, allowing the individual character of the coffee to speak.
Some people are put off coffee made in a cafetiere as it contains sediment. However, some sediment is desirable as it adds texture and mouthfeel to the cup.
1. Boil Water: Fill the kettle with enough freshly drawn water to fill the cafetiere twice over and bring to the boil.
2. Grind and Weigh Coffee: If you’re grinding your own coffee, grind it whilst waiting for the kettle to boil. The coffee should be ground very coarse (like sea salt) with the largest particles approximately 3-4mm in length. If you buy your coffee pre-ground and it’s not very coarse, reduce the infusion time (see Step 7).
You will need 6g of ground coffee for every 100ml of water. So if you're planning to make 250ml of coffee, you'll need 15g of grounds; for 1ltr you'll need 60g.

If you don’t have a set of digital scales, as a general rule of thumb: a tablespoon holds approximately 5g of coffee and a coffee scoop (which is often supplied with a cafetiere) holds 7g.
3. Pre-heat Cafetiere: Once the kettle has boiled, fill the cafetiere with boiling water and insert plunger.
4. Add Ground Coffee: After pre-heating your cafetiere for 1 minute, discard the water and give it a quick wipe. Now add the ground coffee.
5. Add Water: The remaining water in your kettle should now have cooled sufficiently to brew coffee. With the spout of the kettle positioned just above the cafetiere, slowly pour water into it. Fill it to 1cm below the bottom of the spout and start the timer.
By pouring from a low height you’re reducing the amount of agitation caused when the water hits the coffee grounds. It’s difficult to control this form of agitation, so it’s far better to minimise its affect and rely on more consistent methods of agitation such as stirring. Whilst elaborate pours from great heights may look spectacular, they impact on the grounds differently every time, giving inconsistent results to your brew.
6. Stir: Give the coffee solution two gentle stirs to insure the grounds are evenly wet. Now replace the plunger, bringing it to rest just above the solution.
7. Infuse for 4 Minutes: Leave the coffee solution to infuse for 4 minutes. Then, using little more than the weight of your hand, press the plunger down.
8. Serve Immediately: Serve the coffee immediately. Don’t leave it in the cafetiere as it will continue to slowly extract.
If you’re not going to drink the coffee straight away, transfer the solution from the cafetiere into an insulated flask.
The above method may need some fine-tuning to find the 'sweet spot' and achieve a truly tasty cup of coffee.
- Is the coffee balanced – sweet and fruity, not bitter or sour?
- Does the coffee have depth of flavour?
- Have I captured in the cup all the flavours I smelt from the ground coffee before brewing?
If your answer is ‘NO’ to any of the above questions you should experiment with the method by making some adjustments.
If your coffee tastes sour or lacks sweetness try one of the following:
- Use hotter water to brew with i.e. reduce the pre-heating time in Step 4 so the remaining water in the kettle has less time to cool
- Grind the coffee slightly finer
- Lengthen the infusion time (Step 7)
If your coffee tastes bitter or lacks fruitiness try one of the following:
- Use cooler water to brew with i.e. increase the pre-heating time in Step 4 so the remaining water in the kettle has more time to cool
- Grind the coffee slightly coarser
- Decrease the infusion time (Step 7)
- Increase the ratio of coffee to water i.e. instead of 6g per 100ml try up to 7g per 100ml.
If you find the coffee too strong, rather than reducing the ratio of coffee to water, you should brew less coffee and then simply top it up with hot water after you've finished brewing.
Cleaning Your Cafetiere / French Press
As soon as possible after use, the grounds should be removed from the cafetiere and all parts should be rinsed under hot water. Then, once convenient, the cafetiere should be washed in soapy water, or if safe, in the dishwasher.
Every week the filter (i.e. the two metal discs and mesh filter) should be dismantled and soaked overnight in very hot water to remove any build up of oils. Alternatively, you can achieve the same results by soaking the filter parts in Puly Caff for 15 minutes.
