IMPROVED CONSISTENCY – With a design that achieves the same tamp every time. The amount of pressure you apply is simply controlled by a spring inside the tamper itself. Moreover, it comes with 3 interchangeable springs to suit your preference. RIPPLE BASE - Created to minimize the risk of a doughnut extraction, the indentation on the coffee bed made by the ripple tamper allows controlled water channeling and even saturation of the grounds. UNIQUE DESIGN - Our coffee tamper is spring-loaded and does not require additional adjustments. It has an ergonomic handle with a comfortable grip that allows you to push ground coffee easily. Made with stainless steel anodized aluminum, these tampers can withstand time and high volume shifts. Level Tamping - The ingenious design of leveling plate ensures your tamping level every time by resting on top of the filter basket as you press down on ground coffee. Press and turn clockwise at the same time when tamping to create the best level result. SUITS 54MM BASKETS: The 53.3mm base is designed to fit 54mm Breville / Sega Portafilters which are tapered (Suitable Breville / Sage models including the Barista Express, Pro, Touch, Bambino Plus, Infuser, and Duo-Temp Pro).
