Now that you have brewed the coffee, where do you put the waste coffee grounds? Well, this can be a headache, particularly if you are operating a busy coffee shop. The answer to all this is a knock tube. Whether you are brewing coffee at home or you are running a cafe, this is one of the most important tools you need in your coffee kit.

Coffee Knock Box Tubes

Coffee Knock Box TubesA knock tube is simply a container designed with a bar/tube across the top, and its main purpose is to enable for the easy disposal of the used coffee grounds. The tube is usually covered with a rubber shock absorber that helps to cushion the impact and thus greatly reduce the chances of splitting the tube. Note that you have to hit the Portafilter hard against it to make sure that the waste coffee grounds have been disposed of for the next brewing.

Commercial Knock Tubes

For those operating a busy coffee shop, a knock box is an essential tool that you must have in your coffee kit. It will be complicated to dispose of the used or waste coffee grounds effectively without this simple tool. Imagine this, you have tamped the coffee and passed the heated water through the grounds, the used coffee grounds stick to the Portafilter and getting them out can be difficult.

You need somewhere you can hit the Portafilter hard so that all the grounds can come out easily without littering your place. This is why it’s important to have the knock tube in your café. You just need to hit in the rubber, and the Portafilter will be ready for the next cup of coffee.

But we always advise baristas, especially those running coffee shops, to select the knock tube carefully. First, you need to understand that you need it more than anything else. Do you know how much time it would take you to get rid of the waste coffee beans from the portafilter without one?

You can only understand this properly if you are operating a busy coffee shop. The lack of this essential in your café can slow down your operation, and these delays can cost you customers in the long run. All you need is to look for features that will make its operation effective. First, you need to check the size of the knock tube based on the number of customers that you receive daily and the space you have available. Make sure that the knock tube capacity can serve you at least a whole day.
