Bottomless Naked Portafilters for Espresso Machines
come complete with a 3-shot 21g filter basket. It helps to control and diagnose the flow and extraction of espresso shots and assures a pure espresso result with a great crema. It can therefore serve as an amazing and indispensable espresso tool for training purposes, because "channeling" (uneven water distribution) will show up if the coffee grounds are not evenly compressed/tamped in the filter.
