What you’ll need:
Espresso Machine, Portafilter, Tamper, Dry Cloth, Cup, Digital Scale, Timer
STEP 1
⇒ Use a clean, dry cloth to thoroughly wipe the portafilter so it is free of any coffee grounds and residual oils.
STEP 2
⇒ Weigh the coffee.
STEP 3
⇒ You’ll want to use a grind setting that will have the espresso pulling for 25-30 seconds. If it’s pulling faster than that, grind finer. If it’s pulling slower, grind coarser.
STEP 4
⇒ Place the coffee into the portafilter.
⇒ Make an even bed of coffee. Don’t leave any gaps or mounds.
STEP 5
⇒ Grasp the tamper and press firmly down on the coffee in the portafilter.
⇒ Use enough pressure to compact the coffee grounds into a puck.
STEP 6
⇒ Gently insert the portafilter and ensure it is seated tightly in the grouphead.
⇒ If the portafilter is inserted to roughly, cracks will form in your espresso puck and cause an uneven extraction.
⇒ Start your timer at the same time that you start the espresso.
⇒ The shot should take between 25-30 seconds.
STEP 7
⇒ Once you’ve pulled your espresso, remove the portafilter from the grouphead, and knock out the spent puck from the portafilter basket into the trash or a knockbox.
⇒ Clean the portafilter with hot water and dry it with your cloth.
