However, if a flat filter is used in the portafilter, or if much more than 7g (for a single cup filter) or 14g (for a double cup filter) is used, the space between the coffee powder and the group head can be too small for optimal water distribution. For this purpose, the Convex Tamper Base can be used, as it leaves a cavity in the middle of the pressed powder, for better water distribution.\u003c\/p\u003e\n\u003cp\u003eThe dimensions of the tamper to be used vary according to the manufacturer.
