Espresso Dial-In Calculator

Pulling a great shot at home comes down to three linked variables: your dose (grams in), your yield (grams out), and your shot time. This calculator turns your inputs into a target brew ratio and tells you exactly which way to move your grind size next.

Enter what you dosed and what actually came out, then adjust the target ratio to match your style — from a tight ristretto to a longer lungo — and get precise, repeatable dial-in guidance.
