Abstract
An espresso tamper including a force calibration means is shown. The tamper is optimally handheld. Upon force of a desired magnitude being applied by a user, at least one discrete signal, such as an audible, visual, tactile or electrical signal is emitted. The tamper handle includes an anti-rotation feature. The handle is flared to avoid pinching the user's fingers during operation and to stop the user's fingers from sliding down the handle or in any way touching the base, thereby rendering the tamper more effective and safe. The tamper and force-calibration kit and method of use optimize espresso making.
