What is the perfect flow time for a double espresso?

between 20 – 30 seconds

The volume of water for each shot should be 1 oz. – so after your double shot has reached 2 oz., stop the shot and check your timer. The ideal brewing time you're looking for is between 20 – 30 seconds – if you're running too long or too short, check your grind, dose and tamp, then adjust it accordingly.
