Espresso Grounds Knock Box Buying Guide

What is a knock box?

A knock box is a tub which sits alongside an espresso machine, for when you need to get rid of the puck in your portafilter (i.e the used coffee grounds in the device you use to extract the coffee).

Do I really need a knock box?

Not particularly. Some people may just empty the puck straight into the bin or into a standard tub, but some reasons why a knock box is a better options include:

• Hassle Free – No running to the bin as the box just sits alongside your coffee setup
• Reduces Mess – The grounds need to be emptied out ASAP to prevent them sticking to the filter, but transporting them across the room could mean dripping coffee and grounds falling
• Easy To Clean – The tubs are often made from metal and have curved corners to ensure all coffee is removed, especially if it is damp which could otherwise be a breeding ground for bacteria and germs
• Dedicated Knock Bar – Hitting the portafilter against a surface could result in damage to either side, but the bars on a knock box are specially designed to take the blow and get every bit of coffee out without damage
