About Coffee Brew Ratio
The brew ratio divides water by coffee to express how concentrated the cup is, typically around 1:16 for pour-overs. Consistent ratios make a brew repeatable, and moving from dilute to strong changes extraction and perceived acidity.

Assumptions and limits
- The result is derived only from the 2 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax or compounding frequency into account.
- Figures are rounded for display to 1 decimal place, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
