To brew 1 cup of coffee, you need 15g of coffee and 250ml water.
To brew 2 cups of coffee, you need 30g of coffee and 500ml water.

Step1: Heat the water
Bring 500 milliliters of filtered or bottled spring water (35–85 PPM) to 94–96°C. If you don't have a thermometer, boil the kettle and leave it to rest for 30 seconds to bring it to the right temperature.

Step 2: Pre-warm the cafetière
Pour a small amount of hot water into the empty cafetière and swirl it around, then discard. This pre-warms the glass and helps maintain a stable brew temperature.

Step 3: Add the coffee
Add 30 grams freshly ground coffee to the cafetière. Place it on your scales and tare to zero.

Step 4: Bloom the coffee
Pour the hot water slowly over the grounds, making sure everyone is fully saturated, then start your timer.

Step 5: Leave the coffee to brew
Leave the coffee to steep for 4 minutes undisturbed. Once the time is up, break the crust that has formed on the surface with a gentle stir, then leave it to rest for a further 5 minutes, this allows the grounds to sink and settle to the bottom.

Step 6: Plunge and pour
Place the lid on and press the plunger down slowly and steadily. A little resistance is perfectly normal. Pour straight into your cup and enjoy.

The result is a wonderfully clean, full-bodied cup with a pure, sharp flavour that speaks for itself.
