About this calculator
Calculate the ideal espresso yield and shot time based on your dose, target brew ratio, and grind adjustment, with a breakdown of yield weight and extraction style.
Frequently Asked Questions
What is a brew ratio in espresso?
It's the ratio of dry coffee dose to liquid espresso yield by weight. A 1:2 ratio means 18g of coffee yields 36g of espresso.
Why adjust the ratio for taste?
Some palates prefer more concentrated (ristretto-leaning) or more diluted (lungo-leaning) shots. The adjustment slider shifts the target yield accordingly.
Does shot time matter as much as weight?
Weight is more reliable than time since grind, tamp, and bean freshness affect flow rate, but time helps you sanity-check the shot.
