Best Knock Box for Espresso
Thanks for taking the time to read our UK reviews on the best knock box when making coffee at home. This is a coffee accessory that we believe should be used when making coffee at home. The reality is that many people don't actually use one of these, and we think they are missing out.
If you have a coffee machine at home that can make an espresso, then we are sure that you are very familiar with the routine. You grind your coffee, or use pre-ground coffee, tamper it, brew your coffee and are then left with the used puck inside the portafilter.
Most people will make a short trip to the bin, and dispose of that in there. We have all done that at some time, and one or two solid taps is enough to get it into the bin, and out of sight. After all that costs you nothing except the short trip to the bin.
Why bother with a knock box then you may very well ask? For us there are three main reasons why you should consider buying one. Those are:
- Hygiene - should you really hit your portafilter off the side of a bin with germs and bacteria in there? It is even worse if the filter falls in and you have to fish it out
- Having a knock box in your kitchen looks cool, and also allows you to quickly get rid of the used coffee puck, without any dripping or mess
- It is a great idea if you are planning on recycling your coffee for something like a compost heap as all the grounds are in one place
Do You Really Need a Knock Box?
It is one of those gadgets that divides opinion quite a lot. One one side of the argument are those that say, this is just a plastic box with a bar in the middle that is way too expensive. At the other side of the argument some people say it keeps the coffee area clean, is a safe place to hit your portafilter off, and keeps everything neat and tidy.
Almost every coffee shop has one, and the main reason for that is cleanliness and hygiene. Customers would not be too impressed if they saw the barista whacking the portafilter into a bin. it really shouldn't be any different at home. We also think it does keep things very tidy, and makes sure the portafilter doesn't get damaged.
Tips for Buying a Knock Box
We all learn things from trial and error and also from experience. Most of the writers here at the website have owned one or more of these, so we asked them all for their top tips for buying a knock box. We have listed those tips below, so as you cal learn from their mistakes, and avoid buying a pig in a poke, or a puck in a poke.
- Avoid buying something really small that only holds 5 or 6 pucks as that just becomes a pain to continually have to empty

- Stainless steel is more expensive, but the hard plastic knock bins can crack over time
