Learn how much coffee to use in an 8 cup cafetiere, the ideal coffee-to-water ratio, and how to serve a 1 litre French press for offices and cafes.
Quick answer
For an 8 cup (1 litre) cafetiere, start with 60–70 g of coarse-ground coffee and 1 litre of water. That yields roughly 8 small 125 ml cups or 4 generous 250 ml mugs, and you can adjust the dose up for a stronger brew.
Why the coffee-to-water ratio matters more than the cup count
A cafetiere’s “cup” is usually a small 125 ml serving, so an 8 cup model holds about 1 litre. If you fill it to the top without weighing your coffee, you risk a weak brew. A scale removes the guesswork: 60 g per litre gives a balanced, medium-strength cup, while 70 g suits drinkers who prefer more body.
The grind also affects strength. Coarse grounds extract slowly and are easier to press; fine grounds can slip through the mesh and leave sediment. If you buy pre-ground coffee, choose a French press or coarse setting rather than espresso grind.
Serving a 1 litre cafetiere in offices and cafes
A full 1 litre cafetiere serves about 8 small cups, which is practical for a meeting or a small office round. In a cafe setting, brew in batches rather than letting coffee sit on the grounds, because the brew keeps extracting and turns bitter. For self-service, place the plunger down and decant into a preheated airpot or carafe within a few minutes.
The Black Glass Cafetiere – 8 Cup (1 Litre) has a heat-resistant glass beaker and a dishwasher-safe construction, which helps with quick turnover between rounds. Its 1 litre capacity matches the ratios above, so you can brew a full batch without adjusting the recipe.
Step-by-step brewing and serving
- Preheat and measure: Rinse the glass beaker with hot water, then add 60–70 g of coarse coffee grounds. Place the cafetiere on a scale and tare before adding coffee. Weigh the coffee, not the scoops; scoop size varies too much for a reliable ratio.
- Add water and stir: Pour 1 litre of water just off the boil (about 95°C) over the grounds, ensuring all coffee is saturated. Stir gently with a spoon, then place the lid on with the plunger raised. Check the water temperature; boiling water can make the brew harsh, while cooler water under-extracts.
- Steep for four minutes: Let the coffee steep for 4 minutes. Set a timer rather than guessing, especially when brewing multiple batches. Do not plunge early; under-steeped coffee tastes sour and thin.
- Plunge slowly and serve: Press the plunger down steadily with one hand on the lid. Pour immediately into cups or a carafe. For a full 1 litre batch, expect about 8 small cups or 4 mugs. If the plunger is hard to push, the grind is too fine; stop and decant rather than forcing it.
- Clean promptly: Empty the grounds into a bin, not the sink, and rinse the beaker. The Black Glass Cafetiere is dishwasher-safe, but check that the frame and plunger are placed according to the manufacturer’s instructions. Rinse before the grounds dry to avoid staining the glass and clogging the mesh.
