How this service works
Coffee grams for your water (or water for your grams) by method: drip, pour-over, press, espresso, cold brew; rough caffeine.
Output
Returns the calculated coffee grams and/or water volume in mL for the chosen brew method, the ratio string and grams-per-litre figure, approximate brewed liquid volume, a low/typical/high caffeine estimate in mg, caffeine per 240ml serving, and the FDA daily guidance for healthy adults. May include a source citation, disclaimer, and any degraded-mode flags.
Example use cases
Home barista pour-over planning
“I'm making a pour-over with 350ml of water — how many grams of coffee should I use, and what's the caffeine estimate?”
Cold brew batch prep
“I want to make a big batch of cold brew with 2000ml of water — how much ground coffee do I need and how much caffeine will it have?”
Espresso dose and yield check
“For an espresso with 18 grams of coffee and a yield ratio of 2, how much liquid will I get and what's the caffeine range?”
