AeroPress Ratio Calculator
Scale an AeroPress recipe to your mug. Pick James Hoffmann's standard technique or an inverted World AeroPress Championship recipe, set the dose or water, and get the schedule recalculated: water in, steep, swirl, press. Or build a custom immersion recipe from a ratio.
Two very different AeroPress styles
Hoffmann's recipe is a low-dose, fine-grind brew at 90°C: gentle, clean, and forgiving. The championship recipe doses much higher at 85°C with a vigorous stir, for a heavier cup from the same device. Scaling either keeps its character; the ratio and timings move together.
The AeroPress is an immersion brewer, so extraction leans on contact time and temperature more than pour technique. Our guides on brew temperature and extraction explain the levers. The BeanBench app runs these recipes with a guided timer and logs every brew.
