This allows for subsequent pressing. To avoid using the base of the tamper or the wooden handle for this light tap on the filter holder, risking damage to both the tamper and the filter holder arm, you can now tap with the silicone ring integrated into the base.\u003c\/p\u003e\n\u003cp\u003eWhy the name CONVEX?\u003c\/p\u003e\n\u003cp\u003eNormally, the surface of the coffee grounds pressed into the filter holder doesn't play a significant role; whether it's flat or concave, there's enough space between the coffee surface and the dispensing group so that the water can be evenly distributed over the coffee grounds and pass through them evenly. However, if a flat filter is used in the arm, or if much more than 7g (for a one-cup filter) or 14g (for a two-cup filter) is used, the space between the coffee grounds and the dispensing group may be too small for optimal water distribution. For this purpose, you can use the Convex Tamper Base, as it leaves a cavity in the middle of the pressed coffee for better water distribution.\u003c\/p\u003e\n\u003cp\u003eThe dimensions of the tamper to be used vary depending on the manufacturer.
