What Is A Knock Box?

A knock box or ‘bash bin’ is simply a box used to store used espresso pucks after a shot has been pulled. They all have simple, functional designs and are generally made of plastic or stainless steel with a sturdy bar to knock your portafilter on to release the puck. A knock box is a helpful accessory to accompany an espresso machine, making clean up a breeze.

Why Do You Need a Knock Box?

The main reasons you should consider getting a knock box are convenience and cleanliness. A knock box makes clean up a breeze so you can sit back and enjoy that espresso faster! You won’t have to worry about dripping espresso on your floor as you carry your portafilter to the sink or bin. You won’t risk blocking your drain if you are discarding used pucks down the sink or damaging your bin if you are knocking the portafilter on that. A Knock Box is a simple but functional tool that can make life that little bit easier.

The Best Knock Box – The Verdict

We hope this article has given you some more clarity on why to buy a knock box and what to look for in one. Given that they are all very similar in features it really comes down to personal preference. We believe any of the knock boxes on this list will be good-quality purchases. However, the Gridenstein knock box is our personal favorite, with a modern design, solid build and compact footprint.

Types of Knock Boxes

There are three main types of knock boxes; a box or bin, a drawer, or a chute. The box style is the most common for home use, while the other two are typically found in a cafe or office setting which has a far higher turnover.

Box

The box or bin is the most common type of knock box, particularly in a home setting. This is basically a small bin with a bar running across the top to whack the portafilter on. There are a huge variety of options available in different sizes, colors, and designs. The box is the most practical choice for a home barista, it is affordable, compact, and easy to clean.

Drawer

Another option you could go for is a drawer. Drawers are designed to sit under a grinder or espresso machine with the aim of saving space. Given this, they have a sturdy build and a large capacity. They also keep your coffee nook clean and tidy, with any used grounds hidden away out of sight. The downside of a drawer is that they are very expensive. There is a wide range of sizes to cater to popular coffee grinders and espresso machines.

Chute

The final option is an open-bottomed knock chute. This is basically a knock box with an open bottom. It sits on top of a special bin, designed for collecting pucks. An open-bottomed chute is an affordable and practical way of dealing with a high volume of use. We have not included any of these on our list as they are really for a commercial environment and a bit overkill for use at home. But if you do think this kind of knock box would be more suited to your needs the Rattleware and Rhino Coffee Gear chutes are both good options.

What To Look For In A Knock Box? 

When it comes to Knock Boxes there is not much variety. They all have very similar designs and function in the same basic way. Even the prices don’t vary that much. Probably the most important things to consider are aesthetic appeal, size, and sturdiness.

  • Aesthetic appeal: This is one of the most important things to consider when buying a Knock Box. As it will be sitting on your bench top all day you want something that will look good and suit your kitchen décor.
  • Size: Consider how often you are going to be using your Knock Box. If it is a lot you will need a larger box so you don’t have to empty it as often. Also, consider how much room you have on your bench. If you are pushed for counter space you might want to opt for a more compact knock box, that could fit beneath the group head on your espresso machine when not in use.
  • Sturdiness: If you are going to invest in a Knock Box you are going to want one that will last and can stand up to being knocked without damaging the bar or portafilter. 

How To Reuse Coffee Grinds

Instead of simply chucking your used coffee pucks in the garbage here are a few surprising eco-friendly alternatives:

  • Coffee grounds make a great natural fertilizer for your garden when added to compost. They help to mask the smell and also stabilize the pH level in the compost allowing foods to degrade quicker.
  • Coffee grinds are a natural bug-repellent. You can sprinkle the dry coffee grounds around your house to keep bugs away.
  • Dry coffee grounds can be sprinkled in the bottom of your rubbish bin to stop the odor.
  • Dry coffee grounds can be used to clean hands to remove strong odors such as garlic and onion.

Happy Buying!
