What is a coffee knock box?
Also known as a coffee grinds bin or espresso dump box, a coffee knock box allows you to quickly and easily empty used espresso pucks out of your portafilter.
Coffee knock boxes are one of the simplest and best coffee accessories to add to your home barista kit. The benefits include:
- No more walking the portafilter across the kitchen to the bin, dripping espresso on the floor along the way
- They prevent damage to your bin and your portafilter
- By keeping the grinds separate you can re-use them in your compost or as an indoor plant fertiliser
- A quicker way to make more than coffee at once, as the grinds bin is positioned right next to your machine.
What to consider when buying the best coffee grind bin
When it comes to the best knock box for espresso, there are some great options on the market.
There are a few things to consider though, such as which style, size and material the knock box is made from.
To purchase a coffee knockout bin that is perfect for you, consider the following factors.
If you already know the features you need, click here to skip straight to the reviews.
Style
The most common style of coffee machine knock box is your simple bin design.
However, there is also the option of a drawer or tube style. Each type has its pros and cons.
- Bin: A bin style is just a small, sturdy bin like product with a knock bar running across the top. These are cheap, practical to use, simple to clean and easy to store – perfect for the home barista.
- Drawer: A knock out drawer is usually installed under the coffee machine or grinder to save space. An espresso knock box drawer is a more expensive style of knock box and generally only used in cafes or busy kitchen offices.
- Tube: This is similar to the bin style, except as the name suggests, a coffee knock tube is a tall narrow type of bin, which is freestanding and best suited to busy cafes with a high turnover.
Size and capacity
Knockbox coffee bins come in a range of sizes to suit the amount of espresso you drink and therefore the number of used pucks you want it to hold before emptying.
For the average household, a small bin style would be more than adequate for your used grounds, as they should be emptied every few days anyway to prevent mould growing in the bin.
However, for a busy office kitchen or small café, you’re best to buy a coffee grounds bin with a larger capacity, so you’re not continually emptying and cleaning it each day.
In term of size, you’ll also want to consider where you’re going to store the coffee grinds bin.
If you have plenty of space, this won’t be a major concern, but smaller kitchens with less counter space or room in the cupboards will benefit from a small sized coffee knock out box.
Material
Given the constant beating a knock box espresso bin gets, it’s vital that it is made with sturdy and durable material.
The most common materials used to make espresso knock boxes include stainless steel or durable plastic, often with a rubber coating on the knock bar.
Stainless steel is a durable option, but these are usually a more expensive option as well as heavier and generally not dishwasher safe.
Plastic made knock boxes are generally more affordable and easier to clean thanks to being dishwasher safe.
While plastic is not usually recommended for its durability, you can get some great quality knock boxes made from high quality plastic. Usually, they come with a rubber coating in all the important areas to make them extra durable and withstand the regular beating.
Often the material of the body of the coffee grounds knock box differs from the knock bar itself. The knock bar is the part of the knock box constantly whacked with the portafilter so is the most important part of the product to consider.
Generally, knock bars are made of stainless steel or plastic and are usually covered with high quality rubber or silicone, which provides some padding and cushioning when the bar is hit. A stainless steel knock bar is far more durable than a plastic one.
Another area to consider is the base. Look for knock boxes with non slip bases to ensure the box stays in places as it’s hit.
You certainly don’t want to knock over the knock box creating a huge mess with used espresso grounds everywhere.
Cleaning
An espresso machine knock box becomes quite dirty after being used, so the easier they are to clean, the better.
The easiest ones to clean are those that are dishwasher safe. Some knock boxes come with a removable inner, which is dishwasher safe, while the outside might just require a wipe down with a damp cloth.
A tube knock box is much harder to clean due to its long narrow shape. The best thing to do with this type of knock box is to use a bin liner.

- Dimensions: 11 x 11 x 10 cm
- Materials: ABS Plastic and rubber coated steel bar
- Dishwasher safe: Yes
Arguably one of the most popular knock boxes on the market is the Dreamfarm Grindenstien DFGR1280 knock box. I own the Grindenstein knock box and it is still going strong after many years of daily use.
At around half the size of the previous Breville knock box, the Grindenstein home knocking tube is a small bin that has been designed to sit on the drip tray of your espresso machine when not in use. It fits around 8-10 pucks at a time.
The Grindenstein body is made from hard BPA free plastic which aids in keeping the product lightweight as well as low cost.
The knock bar has a solid steel core and a rubber sleeve that makes this one tough little coffee bin. The rubber protects the portafilter from any damage and keeps noise to a minimum. It also features a non slip base.
This coffee dump box espresso bin is dishwasher safe which makes it super easy to clean. Its small height makes it really easy to store away too.
Another little bonus with the Grindenstein coffee knock box is that it comes with a booklet that provides lots of tips and suggestions on recycling your used coffee grounds as fertiliser for the garden.
For a knock box, the Grindenstein looks pretty good! It will certainly look rather classy on your kitchen bench. There is a larger size if this one is too small plus it comes in three colours to choose from, including red, black or silver.

3. Avanti Compact 15100 Coffee Bin Review
Key Features
- Dimensions: 14 x 14 x 10 cm
- Materials: Durable plastic and rubber coated tube
- Dishwasher safe: Yes (container only)
A little bit bigger than the previous Grindenstein knock box, the Avanti is another great option for home baristas not wanting an overly big espresso dump box. It also comes at a super great price, making it the perfect solution for those just after something inexpensive.
The Avanti Compact is made from durable plastic. The removable knock bar features a thick rubber sleeve to absorb the striking force, prevent damage to the portafilter and reduce noise.
The knock box is also dishwasher safe and the removable knock bar makes emptying and cleaning super simple.
Another excellent design feature is the anti slip base on the bottom of the knock box. This prevents any movement while in use.
Like the Grindenstein, this small coffee bin is designed to sit on the drip tray of most espresso machines, which is perfect when space is a bit tight.
Pros
- Removable knock bar
- Dishwasher safe container
- Small and compact
Cons
- May be too big for some drip trays
- All plastic construction

4. Joe Frex JF-KCB Wooden Coffee Knock Box Review
Key Features
- Dimensions: 13.75 x 13.75 x 13.75 cm
- Materials: Wood and PVC plastic
- Dishwasher safe: No
For something a little different, the Joe Frex knock box is a cube shaped box with a removable inner bin enclosed by a great looking painted wooden box.
The cubed wooden body provides an excellent stable base for knocking out the portafilter’s espresso grounds and the rubber blocks on the base help protect your benchtops.
Inside the wooden body, you’ll find a durable PVC container that can be lifted out to dispose of the used espresso grounds easily. The knock bar is also removable. In fact, the knock bar keeps the PVC container locked inside the wooden case.
Unfortunately, neither the wooden case nor the PVC container is dishwasher safe so you’ll need to handwash them both.
Pros
- Removable inner bin
- Unique wooden design
- Replacement pieces available
Cons
- Not dishwasher safe
- Painted and not stained wood
There’s no question about it, the Joe Frex wooden coffee knock box has a lovely classic design and will look fabulous in any kitchen. However, it is a little on the expensive side for the home, so it won’t be the right choice for everyone.
