Morning coffee is a staple in many people’s daily routines. The anticipation of the finished brew is half the fun; the other half is with the beans grinding and the toasted aroma of the coffee. And, of course, when you’re done with your espresso, you’ll need to get rid of the used puck. You could walk over to your trash can but accidentally damage your portafilter. To avoid this, you can use a knock box. With a knock box, tap the portafilter next to your espresso machine.

Best coffee knock box in the market today
We compiled our top 5 picks for knock boxes to help you decide what you should buy. Some of these picks prioritize value for money, while some focus on style and compactness.
1. Breville BCB100 Barista-Style Coffee Knock Box – Top Pick
If you have a large family and make several cups of coffee daily, this is an excellent option because you won’t have to empty it as often. Despite its large capacity, it has a reasonable price. In addition, the inside cup is detachable and dishwasher safe, making it one of our favorite features.
There are, however, drawbacks to using the BCB100. While other models’ plastic polymer bars withstood extensive testing with no dents or other damage, this one did not fare as well. In addition, it would take up too much room on your counter.

- Awkward bar height
- Takes up too much counter space
- Polymer bar is not that durable
2. Cafelat Tubbi Knock Box – Most Compact
Cafelat produces a wide variety of high-quality espresso-related items. If style is your priority, you should go for this since the sleek plastic Cafelat Tubbi is available in five hues, one of which is a vivid yellow-green.
Tubbi’s removable crossbar, which is not permanently attached to the box, is a standout feature. This little container is ideal for use with portafilters that feature a narrower opening. In addition, it’s made of sturdy ABS plastic, making it quieter since the plastic dampens vibrations.

It can only hold about five or six pucks before it needs to be emptied.

What is a knock box?
Also known as “bash bin,” t,” knock box is a horizontal bar against which the portafilter can be smashed to release the puck. You must place it beside your espresso machine for convenient puck disposal after each shot.
Reasons why you should invest in a knock box
Consider these possible returns on your investment in a knock box before you decide against it.
Prevents potential portafilter damage
When removing the puck from the portafilter to the trash, you must apply pressure to ensure no debris remains. This puts your portafilter at risk of damage. However, if you have a knock box, that puck will be easily collected, and you won’t have to apply physical force on your portafilter.
Affordable and requires little upkeep
Knock boxes, used to brew espresso, are a relatively cheap accessory requiring little upkeep. Occasionally, you should wash them. However, they may be cleaned with little effort.
It prevents the buildup of odor.
An additional benefit of using a knock box to store used coffee grounds is that it helps to contain the odor. Wasted coffee grounds have an offensive odor, so keeping them from piling up is important. The odor will permeate your entire home if you throw them out.
Various types of knock boxes for espresso
You may put the countertop knock box wherever you like on the counter and pull them behind the appliance when you’re done cleaning the back. That is why they are the most user-friendly choices. However, consistently knocking portafilters at an elevated level, especially for shorter persons or extra-tall counters, may not be ideal barista ergonomics because of the stress it places on the wrists.
The floor standing knock box
This is the best freestanding option for cafes in terms of maximizing counter space. You no longer have to attach, let alone install it. In addition, the knock box can be customized to fit your space, which is a huge plus for baristas, but it also means they’ll have to be careful to avoid bumping into it as they do their work.
The drawer knock box
Drawers, another concealed knock box, can be set up in the space beneath a counter. A drawer is a suitable substitute if you desire a built-in knock box but lack the necessary counter space. It can be relocated, albeit it won’t be as easy as picking up a countertop knock box and repositioning it.
The built-in knock box
Compared to freestanding knock boxes, those built into a counter give your cafe a sleeker, more professional look. If you put a container under your counter, the grinds will go there, making that area much easier to clean.
Knock Box Buying Guide
When looking for the best espresso knock box for your espresso grounds, there are a few key factors to consider.
Determine the size and capacity
When choosing the right espresso knock box, it’s important to think about the size and capacity you need. If you’re looking for a knock box for your home kitchen, a smaller capacity box might be suitable.
However, a larger capacity box may be more practical if you have a busy cafe or restaurant. If you’re unsure what size you need, it’s best to measure the number of espresso pucks you typically produce in a day to give yourself an idea of the capacity that would suit your needs.
Choose a material
Once you have determined the size and capacity of the knock box that you need, it is time to look at the material. Knock boxes are usually made from either plastic or stainless steel. Plastic knock boxes are usually more affordable and lightweight, making them great for home use.
However, stainless steel is the way to go if you want a knock box that will last for years. Stainless steel is also more durable and can withstand heavy use in a busy cafe environment.
Consider a design with a handle
The design of the knock box should also be considered to ensure that it is user-friendly and comfortable. Many espressos knock boxes feature handles that make it easier to move them around. The handle should be easy to grip and should be able to hold the weight of the box with ease. It should also be made from a durable material that won’t easily break or crack.
Evaluate the quality of construction
When choosing an espresso knock box, it is important to evaluate the quality of its construction. A well-constructed knock box will be made of durable materials, such as stainless steel or wood, and should have non-slip rubber feet to ensure stability.
Additionally, look for a knock box with a securely attached handle that won’t come loose over time. The Breville BES001XL Knock Box Mini is a great example of a knock box with high-quality construction, as it is made of stainless steel and has non-slip rubber feet.
Shape and design
Once you have determined the size and capacity of the knock box that best suits your cafe, it is time to look at the shape and design of the knock box. Knock boxes come in various shapes and sizes, including round, rectangular, and square. Some designs may even include a handle for easy carrying and storage.
Consider the space available and the aesthetic that best fits your cafe’s interior design when selecting a knock box shape or design. For example, a rectangle or square knock box with a handle might be the best choice if you have limited counter space.
