Dry coffee for this batch
| Stage | Add | Scale reads |
|---|---|---|
| 1 · 15% | 90 g | 90 g |
| 2 · 35% | 210 g | 300 g |
| 3 · 50% | 300 g | 600 g |
“Per portion” refers to input brewing water. It does not promise a final cup volume. Check your brewer capacity; stage splits are your choices.
The calculation
Total input water = portions × input water per portion, or the directly entered total. Dry coffee = total input water ÷ denominator. Each pour = total × stage percentage ÷ 100. Stage percentages must total 100%; cumulative readings show what the scale should read, assuming it is not reset between pours.

One pot for three
Three portions of 200 g of brewing water give 600 g input water. At 1:16, use 37.5 g of coffee. A 15% / 35% / 50% plan adds 90 g, 210 g and 300 g, with scale readings of 90 g, 300 g and 600 g.
How it works ↗Four ways to make the numbers clear.
Coffee-to-water ratio
Choose a coffee-to-input-water ratio and calculate in either direction, using grams throughout.
Open tool↗Espresso ratio
Calculate dry coffee dose, beverage yield or their ratio. Keep shot time with your recipe.
Open tool↗Coffee dilution
Use a measured starting TDS and a target TDS to calculate how much water to add.
Open tool↗A few useful answers
Understand the numbers. Keep your own taste.
Will this tell me the best ratio?＋
No. Ratios, pour splits and times are user choices. The presets are editable examples, not universal recipes or a promise of extraction or flavor. Adjust to your coffee, grinder and brewer.
Does 600 g of brewing water make 600 g of coffee?＋
Not necessarily. Grounds retain water, and evaporation and equipment also affect the collected drink. The batch planner scales input water and does not predict final beverage volume.
Can I estimate TDS from the brew ratio?＋
Brew ratio alone does not provide measured strength. Use an appropriate coffee refractometer and its measurement procedure for a real TDS result. The dilution example is illustrative.
Where are my saved recipes?＋
