摘要： The invention relates to coffee packing and dosing devices and machines and more particularly to a portafilter dosing tools used to control the amount, distribution and/or packing of ground coffee within the filter basket of a portafilter prior to extraction. In one aspect the invention provides a device for vibrating the filter basket to vibrate coffee grounds therein to promote levelling and devoiding prior to tamping. In other aspects the invention provides machines and methods for filling a coffee filter basket with tamped ground coffee to a target level. In still other aspect the invention provides a tool for manually administering a uniform tamping force to coffee during tamping.
