Coffee knock box or knockout drawer – what are they?

First of all a coffee knock box is a container kept to the side of an espresso coffee machine. The coffee maker ‘knocks’ the used or spent grounds into the tube or box. Knocking into a box or drawer saves time. It also helps to keep the coffee making area clean and clear.

When the box, tube or drawer is full it will be emptied into the bin. Used coffee grounds make efficient organic fertiliser for lawns. Moreover for flower beds too. However the consequent release of  Nitrogen means it is not good for vegetable patches.

The hard to break designer coffee knock box. Environmentally friendly, designed by Crema Pro.  A strong manufacturer of espresso coffee machine accessories.

THE 175mm diameter versions work well in both domestic and commercial scenarios.   All things considered there is no better knock box available for the money.

The 110mm version is strictly for domestic situations. It is far too small to be sat next to a 2 group machine. The 110mm version does not have the capacity to cope with a commercial set up.

Cafelat Home Knock Box

The Cafelat Home knock box is a small unit designed for domestic coffee making. The boxes are small and sturdy. They come in red or black coloured plastic. The base has a small built in rubber gasket for worktop protection.

Most noteworthy of these boxes is the knock bar. These are sturdy and will no doubt last. The over all  design however is as basic as they come.

These units remind me of building sand castles on the beach as a kid. They look like something a garden centre would give to transport new plants home with. There’s no imagination or passion here, just a dull thuddy and rather ugly cheap looking box.

The gasket on the bottom does not look like it will last that well, it’s thin and unsubstantancial. I really do not rate these boxes at all. That said from a black and white point of view, it does what it says on the tin and if basic is your thing you might just love it.
