How to calculate
Estimate extraction yield from dry dose, final beverage mass and measured TDS.
Extraction yield =
beverage*tds/dose %Dissolved solids mass =
beverage*tds/100 gBeverage to dose ratio =
beverage/doseWorked example
- Dry coffee dose (g): 20
- Brewed beverage mass (g): 300
- Beverage TDS (%): 1.35
- Extraction yield: 20.25 %
- Dissolved solids mass: 4.05 G
- Beverage to dose ratio: 15
Assumptions and limits
TDS must be a calibrated mass percentage for the beverage. This mass balance does not measure flavour or prescribe a brewing target; refractometer sampling matters.
Results are rounded for display; calculations use unrounded values. Read our calculation methodology.
Understanding the result
Estimate extraction yield from dry dose, final beverage mass and measured TDS. Multiply beverage mass by TDS divided by 100 to find dissolved solids. Divide that solids mass by the dry dose and multiply by 100.
When this tool is useful
Multiply beverage mass by TDS divided by 100 to find dissolved solids. Divide that solids mass by the dry dose and multiply by 100.
