What does this tool do?
French press coffee is full immersion, so the dose and grind control the strength. A medium strength uses about 1 part coffee to 15 parts water by weight; use a finer ratio for a bolder cup and a wider one for a lighter cup.
The Formula
Coffee (g) = water (ml) ÷ brew ratio; 1 tbsp ground coffee ≈ 5.5 gFrequently Asked Questions
How fine should the grind be for a French press?
Use a coarse, sea-salt-like grind. Too fine and the mesh lets sediment through; too coarse and the coffee tastes weak even after a long steep.
Why does my French press taste bitter?
Over-extraction usually comes from too fine a grind, water that is too hot or steeping too long. Try a coarser grind or a shorter steep before changing the coffee dose.
