Dose finely-ground coffee into your portafilters. Try and match the dosage to the recommended size of your portafilter baskets. We recommend brewing espressos at 1:2 ratio. So if we dose 20g of coffee, we will pull 40g of liquid espresso.
The total brewing time should come up to anywhere between 25 - 35 seconds. Grind your coffee finer if your shot is too quick and grind coarser if its too long.
Essentially, espresso brewing is about finding the right combination of variables - Dose, Brew Ratio and Grind Size, which allows you to brew the right amount of coffee within a stipulated time.
