Double-Headed Espresso Tamper and Distributor by Disenkelubo The 51mm Palm Tamper side creates a perfectly flat tamp surface every time, therefore creating a consistent puck density. With it’s height adjustable collar you can adjust your tamp depth so that you tamp perfectly for your desired coffee dose. HERE'S HOW IT WORKS: STEP 1 - Load your portafilter basket with the desired amount of freshly ground coffee. STEP 2 - Retract the distributor side to it's shallowest depth, and place the distributor on your portafilter, blade side down. STEP 3 - Gently spin the distributor until your coffee grounds have been evenly distributed and leveled. If the distributor does not reach the coffee, adjust the depth accordingly. Note: you do not want to be applying heavy pressure to the grounds at this stage -- only enough to level the coffee in the basket. STEP 4 - Flip the distributor over and extend the tamper (flat side) to its maximum height. Tamp your grounds to your desired pressure. STEP 5 - For consistent tamping every time, adjust the tamper depth so it matches the depth of the tamp you created in Step 4.
