FITS 54MM BREVILLE PORTAFILTERS -- 53mm base designed to work with the tapered Breville 54mm portafiler baskets, including the Barista Express, Pro, Touch, Bambino Plus, Infuser and Duo-Temp Pro CONSISTENT SHOTS EVERY TIME - Leveling your grounds before tamping creates a uniform and consistent tamp ADJUSTABLE DEPTH - Set your desired tamping depth for consistent tamping pressure every time DOUBLE SIDED - Distributor/Leveler and tamper in one HEAVY DUTY - Aluminum sleeves and heavy 304 stainless steel base - 1lb 3oz total weight A key variable in making a great shot of espresso is achieving a consistent tamp. Tamping your grounds unevenly, or with too little or too great of a tamping pressure, will cause the water to extract through your grounds inconsistently, resulting in poor quality espresso. Unevenly tamped grounds can cause cracks or channels in the coffee puck during extraction, and tamping too hard or too soft and cause the shot to pull too slow, or too fast. This adjustable coffee distribution tool and tamper is a simple and effective way to remove those variables from the equation. Use the distribution/leveling side to evenly distribute the grounds in your portafilter, then flip to the adjustable tamper side for a uniform tamp, every time. Quick, easy and consistent. 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.
