After you've crafted a delicious morning espresso, simply tap your filter on the bar to release the grind. the Oracle, the Oracle Touch, the Duo-Temp Pro, the Smart Grinder Pro, the Bambino Plus, The Barista Touch, the Dual Boiler, the Barista Pro and the Barista Express. Well I have good news, for them and you, because a knock box is the type of thing that you might not have, but also something that you definitely should!

Now time to look at a knock box from one of the most prolific coffee equipment producers in the world, Italian giants De’Longhi. I was wondering if anyone could recommend a lift or elevated piece of metal so the cups are closer to the spout. We’ve all been there (I’m assuming the non-espresso machine folk have left us to it by now) – you’re just about to empty the coffee puck, full of moist, used coffee grounds and you realise you now have to traipse through the kitchen, dripping coffee as you go. The technical storage or access is strictly necessary for the legitimate purpose of enabling the use of a specific service explicitly requested by the subscriber or user, or for the sole purpose of carrying out the transmission of a communication over an electronic communications network. On emptying though, a nice little touch from Dreamfarm is that you get a little booklet which details how to use coffee grinds as a natural fertiliser – it’s nothing that you couldn’t find on the internet, but it’s handy to have there.Measuring 17cmx17cmx17cm, but in an oval shape, it is larger than the Sage product that we looked at above, but certainly isn’t large enough to cause a problem on your kitchen work surface – it should fit in nicely around your other appliances. Not only that, but keeping all of your grounds separate from the rest of your waste means that you are able to distribute them all over your garden – coffee grounds are wonderful for many different types of plants.

If you don’t have an espresso machine, one that uses coffee grounds rather than pods, then you don’t need to read on – a knock box is not something you need at this moment in time. A dedicated container that you can keep right next to your espresso machine, ready to receive your used coffee grounds. This is another knockbox that I would describe as ‘a feature’ for your kitchen – something that you would have out in view rather than hidden away under your espresso machine. If, like me, you consider your coffee drinking as not just a way to get caffeine into your body, but as a hobby, you’ll be well aware that you end up accumulating a lot of different pieces of equipment.

This is a great place to start our list of the best knockboxes because it is just a classic example. Not only that, but you also end up whacking the portafilter on the side of the bin to get as much out as possible – I mean, who knows what sort of germs you are coming into contact with there. For many years I have looked on at gorgeous coffee machines with the hope of one day purchasing one. The next product on our list is this neat little box from German kitchen utensil manufacturers, Cucino. There are plenty available though, so we have compiled this guide to help you decide which one is the best knock box for you.The non-slip rubber bottom is a handy addition as it means you can have full confidence that it’s not going to move when you’re hammering the portafilter against it.
