A 1:2 ratio is an editable example. Time does not enter the ratio calculation.

Target beverage yield
Yield is the espresso collected in the cup. Shot time is a record, not a prediction or a test of flavor. Water put into the machine is not used here.
The calculation
Beverage ratio = mass of espresso collected in the cup ÷ dry coffee dose. Yield = dose × denominator; dose = yield ÷ denominator. Espresso yield is the liquid beverage leaving the machine, not water put into the tank. Shot time is recorded independently.
Your recipe notebook 0/10
Save a recipe when it is ready. It will stay in this browser; export JSON or CSV for your own backup.
Record a shot, repeat the setup
An 18 g dry dose and 36 g beverage yield give 1:2. A recorded 28-second shot is a note about that shot; the calculator does not predict time, grind setting or taste.
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↗Batch brew planner
Scale your brewing water for a shared pot and split it into a pour-by-pour plan.
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.
