Metallurgica Motta Coffee Knock Box

Store your spent espresso grounds, with this domestic knock box from Mazzer.

A knock box is used to store spent espresso grounds after a shot of espresso has been pulled. Because espresso grounds are typically very hot after extraction, knock boxes need to be sturdy. The stainless steel construction of this Mazzer knock box makes it incredibly robust and durable to withstand the heat and also against the knocks and blows that are so common in a busy commercial environment. The knock bar is crafted from rubber to resist the repetitive knocking and tapping required to dislodge the espresso grounds after use.
