Shop name:Chong Qing Shuo Yue Ke Ji You Xian Gong Si Fits 58mm handle filter bases. This 58mm espresso tamper base is compatible with all 58mm filter baskets. The rotation of the paddles of the espresso dispensing tool and the downward pressure of the espresso tamper agitate the ground coffee layer and eliminate existing porosity. These pores are responsible for the channeling phenomenon. Without these pores, almost every cup of coffee tastes the same. Our coffee dispenser and coffee tamper hangs over the rim of the bottomless handle while twisting and pressing. This way the surface of the pressed coffee is level and there is no "slope" phenomenon. This "slope" is the main cause of uneven extraction, over-extraction, and high acidity. The espresso tamper and espresso dispensing tool are designed to be height adjustable. You can adjust the height of the tamper and dispenser according to your favorite coffee taste. There are three types of this 2-in-1 espresso tamper and dispenser on the market. The first one is made of aluminum alloy, which is low in cost and not conducive to health; the second is the hollowing out process, which saves material costs, but it is easy to be damaged during use. The third is solid stainless steel technology, which is healthy, beautiful and durable. Our products are made of solid stainless steel.
