Step by Step Guide to Making the Perfect Espresso
Warm the cup you will serve the drink in. Flush group head for 2-5 seconds. Clean the portafilter with a clean, dry cloth or brush.
Dose 15 grams of coffee in the double portafilter then gently pat the side to level the grounds.
Tamp firmly (30-50 lbs. of pressure) with consistent, firm pressure and making sure tamper is level. Clean any loose grounds from the rim of the portafilter, and insert into the group head.
Start the extraction immediately and observe the flow. The espresso should begin to flow in 3-5 seconds. Total extraction time should be 23-27 seconds to achieve 1 ounce per shot of espresso, including crema.
Espresso shot should have a uniform, caramel colored layer of crema on top.
Serve immediately and enjoy. To finish, remove the portafilter and knock out the grounds. Rinse, and return to the group head.
