Updated October 2026 · French Press Recipe Series
Hotter water extracts coffee faster. In the French Press Recipe Series the water temperature rises with the density of your roasted beans, from 80 °C for the darkest roasts to 100 °C for the lightest, across all 121 recipes.
80 °C for the darkest roasts, 90 °C in the middle and 100 °C for the lightest (Recipe 61, 0.390 g/ml). Light roasts need hotter water to extract fully; dark roasts extract easily and turn bitter if the water is too hot.
Where it is measured
The recipes give the temperature of the water as you pour it onto the grounds. Heat your water to that figure, ideally with a variable-temperature kettle. James Hoffmann’s method uses water just off the boil; the series adjusts the temperature to your roast instead.
Heat to the temperature shown, then pour as soon as the kettle is ready.
In a press, all the water sits with the coffee for the whole steep, so the temperature you start at matters from the first second. A cold press will take some heat from the water, so warming it with a little hot water first helps you stay close to the recipe.
Over the 4-minute steep and 5-minute settle the coffee loses heat, so the cup is cooler by the time you pour it. That is normal. The starting temperature is the part the recipe controls.
The range
The temperature rises in a straight line with density, about 1 °C every six recipes, from 80 °C at 0.330 g/ml to 100 °C at 0.450 g/ml, rounded to whole degrees.
0.330 g/ml, the darkest roasts (Recipe 1)
0.390 g/ml, the middle (Recipe 61)
0.450 g/ml, the lightest roasts (Recipe 121)
And in between:
Recipe 21
Recipe 41
Recipe 81
Recipe 101
Why this range
Temperature controls how quickly the water pulls flavour out of the coffee. A press steeps for several minutes, so the series uses temperature, together with the ratio, grind and dose, to match the extraction to each roast.
Dark roasts are brittle and give up their solubles easily. Cooler water keeps bitterness in check.
Light roasts are dense and resist extraction. Water at 100 °C, the temperature Hoffmann’s method uses, helps them extract fully so they taste sweet and clear rather than sour.
It’s the same principle as the espresso temperature calculator and the filter temperature guide: hotter for light roasts, cooler for dark. The press has the widest range of the three, 80 to 100 °C.
Where it sits
Recipe 61, at 0.390 g/ml, is the middle of the series, and its temperature is 90 °C.
James Hoffmann’s French press method uses water at 100 °C. The series reaches that for the lightest roasts and comes down as the roast gets darker.
The Specialty Coffee Association’s Golden Cup standard recommends water at 93 °C ±3 °C where it meets the coffee. The middle of the series sits inside that window; the lightest roasts go hotter and the darkest go cooler.
Every recipe steeps for 4 minutes and settles for 5, so temperature, ratio, grind and dose do the work of matching the brew to your roast. See the brew time guide.
