Espresso easy release filter
An easy release filter for espresso brewing is provided. The easy release filter comprises a portafilter having a circumferential recessed groove within its interior wall. A spring may be placed and secured into the recessed groove. The spring is preferably controllable, for example by a tab member, to either of an open or closed position. When toggled to the closed position, added tension can cause the spring to bend or flex into the interior of the portafilter to secure a filter basket therein. When in the open position, the spring may retract into the recessed groove so that the filter basket may easily be removed from the portafilter.
