Work out espresso brew ratio instantly with clear inputs, formula shown and shareable results.
Brew ratio is liquid out divided by dry dose, and flow rate is that liquid divided by the shot time; a normale sits near 1:2 in 25 to 30 seconds. Ratio and time together describe a shot far better than either alone, because the same 1:2 ratio pulled in 15 or 40 seconds tastes completely different.
Brew ratio
ratio = liquid espresso out / dry dose in
Flow rate
flow = grams out / seconds
ratio = liquid espresso out / dry dose in. Brew ratio is liquid out divided by dry dose, and flow rate is that liquid divided by the shot time; a normale sits near 1:2 in 25 to 30 seconds.
Ratio and time together describe a shot far better than either alone, because the same 1:2 ratio pulled in 15 or 40 seconds tastes completely different.
