Are you looking for a high-quality commercial coffee grinder for your coffee business? A durable, reliable, well-made coffee grinder is going to be one of the most important purchases and will determine the overall quality of your coffee. Usually, a commercial coffee grinder will be larger, more powerful, and are equipped with more features than a regular basic home coffee grinder.
However, looking for one can be somewhat overwhelming. That’s why we did most of the grunt work for you! Read on to find the best commercial coffee/espresso grinder for your business.
Why Get A Coffee Grinder?
Well, if you’re looking for a commercial coffee grinder in the first place for your business, then you should already know the importance of commercial coffee grinders. The most obvious reason as to why they’re necessary for brewing coffee because you can’t just brew coffee without breaking down the whole coffee beans into smaller grounds. The main purpose of the grinder is to break down the beans into grounds that range from small to large in order to make a wide variety of coffee drinks.
If the coffee beans are broken down into grounds, it’s more difficult for water to filter through them, since the grounds are more physically compact than whole beans. As the water struggles to filter between the grounds, the flavor of the coffee is extracted. This is why grinders are crucial to making coffee.
Furthermore, grinding coffee right before brewing is the best way to make sure your coffee is as fresh and flavorful as possible. Any professional coffee connoisseur will vouch that freshly ground coffee is better over already ground coffee, which is why choosing the best commercial grade machine to meet your needs is important to how well it will fit your business needs.
Different Kinds of Coffee Grinders
Now, there are many different kinds of coffee grinders for you to choose from when on the market for a big scale commercial coffee grinder. Before you begin shopping, here are some of the important kinds of coffee grinders you should know about before officially choosing your designated grinder.
Across the board, burr grinders have been the preferred grinders of choice for those who are commercially selling coffee. This is because they allow flexibility for grind size, not just with the range of sizes, but also with grind uniformity. This feature makes them a favorite of many professional baristas, as well as commercial coffee shops.
Burr grinders get their name because they consist of two serrated blades that oscillate around one another (hence the name “burr”). These grinders don’t actually cut or slice the coffee beans, but they instead actually grind them together, breaking them down. Furthermore, many baristas tend to prefer burr grinders because they aid in the extraction of oils from within the beans, enhancing the flavor of the coffee.
The two most popular types of burr grinders are conical and flat. There is much debate in the coffee community as to which style is better for both domestic and commercial coffee. Our primary analysis on the subject is that though there are significant differences in both techniques, they both perform well and also create beautifully ground coffee that will make consistently delicious espresso.
Conical Burr Grinders
The most popular burr grinders for many coffee shops are conical burr grinders. The first noticeable characteristic of conical burr grinders is the design of the burrs themselves. Due to the cone-like shape, a conical burr grinder will naturally force the beans downwards in between the blades. The outer serrated burr sits around the venter burr, which is a small erect cone covered in sharp blades, breaking down the coffee beans into smaller pieces.
Many baristas favor the conical burr because it creates something called bimodal distribution. If you were to grind coffee with a conical burr grinder and then observe it underneath a microscope, you’d find that the grounds look uniform in size to the naked eye, but are actually two different sizes. With one grain slightly smaller and one slightly larger, the balance of the two sized grinds both encourages and restricts water flow. Though it may sound a little counterproductive, this method is a favorite of many experienced baristas because it actually makes for a smooth, strong shot of espresso.
Flat Burr Grinders
The flat burr grinders are a much different story. As far as the positioning of the burrs is concerned, flat burrs have two horizontal blades, one that faces upwards while the other faces downwards. Coffee beans are fed in between the burrs and are ground down before dropping between them for a second time. Through this method, the coffee grounds make two 90-degree turns in between the blades to ensure that they’re broken down enough in order to begin brewing.
Unlike conical burrs, the flat burrs are allowed to physically interact with one another. This results in a unimodal distribution, meaning that if you were to hold the coffee grounds under a microscope, all of the grounds would be identical in size. Though this may work for other coarser brewing methods such as pour-overs, drip coffee, and French-presses, it doesn’t do so well for espresso brewing, especially large-scale espresso brewing at a cafe or a coffee shop.
The only minor cons that some baristas complain of when it comes to flat burr grinders are that they can produce more heat and noise while grinding in comparison to its conical cousin. Furthermore, it’s easier for coffee grounds to get stuck in between them. Unfortunately, if this happens often you’ll probably end up wasting more grounds than you’ll actually be using with your flat grinder.
Whether a grinder is a doser or a doserless grinder doesn’t really have anything to do with the method of coffee grinding itself, mainly just the way that ground coffee is dispensed after grinding. Usually, doser grinders have a chamber that the coffee grounds are deposited into, as well as a lever to pull to release the grounds in set increments into a portafilter.
Most doser grinders are electronic, and will accurately divide up the coffee through accurate electronic programming. However, though they are extremely helpful to the commercial coffee industry because it quickly doses out small amounts of coffee to make for efficient espresso brewing. Furthermore, since it grinds larger amounts of coffee at once, you’ll have coffee that’s already been ground and is ready to go during a busy day at a highly trafficked coffee shop.
Instead of depositing them into a reservoir, doserless grinders deliver the coffee grounds straight into the portafilter basket through a chute, making it the quickest method of espresso brewing. Most of them are manufactured with a button on the side of the machine that will control the starting/stopping of dispensing grounds.
As far as ease of operation is concerned, doserless grinders normally require experienced baristas, as they’ll have to eyeball how much coffee is released into the portafilter. Many coffee shops favor doserless grinders because when operated by experienced baristas, they can be very flexible, effective, and can produce some delicious espresso as quickly as possible.
A few more positive traits of these grinders are that they allow for control over the dispensing of grounds, minimizing coffee waste, as well as making sure that coffee is as fresh as possible since its ground according to the barista’s own judgment. The only downside to these grinders is that they require experienced baristas to operate them, as well as the fact that they can produce a bit of a mess since they lack a bin for the dispensing of grounds.
One of the least common coffee grinders used in the commercial coffee setting, stepped grinders are ideal for some baristas because they allow for easy adjustability of grind size. If you’re in a rush to switch grind size and don’t have time to dial in your machine, a stepped grinder can allow easy maneuvering. Often, baristas tend to favor stepped grinders because they are flexible and user-friendly, and they can also “lock-in” a certain grind size. This means that the grind size won’t alter or change after you’ve used your machine several times. This prevents you from having to dial in your grinder more often than you’d prefer.
However, this can be a double-edged sword. Since changing between grind settings can be easily and quickly done, there can be a lack of quality for some grinding sizes. For example, instead of offering a variety of different grind sizes, there may be larger gaps in between a smaller number of grinding settings, creating differences between grind sizes that are only one step above or below each other.
If dialing in your grinder to get the precise grind possible is your main concern, then a stepless grinder may be exactly what you’re wanting. They are more adaptable when it comes to adjustments and the sharp focusing on grind sizes, and they also even have stepped grinders with preset notches to help determine grinding sizes.
Stepless grinders can be a favorite of many baristas because they also include the ability to find the most precise settings as possible for whatever kind of coffee that you’re grinding. As a result, this helps create the most ideal level of extraction possible, and it also allows you to experiment more with espresso brewing. Since they allow baristas to fine-tune their espresso, they can ensure that each shot pulled is consistent in flavor, texture, body, etc. Long story short: if you care about getting the most accurate grind possible for your coffee, then a stepless grinder is worth your reviewing.
Qualities To Look For In A Commercial Grinder
As you begin shopping around for the best grinder to complement your coffee business, it’s important to be aware of what qualities to search for when deciding between which grinder is best for you. Here are just a few that we believe it’s important to consider when narrowing down what the best commercial coffee grinder is for your business.
What Is Your Business?
When considering which commercial coffee bean grinder is best for you, the first thing you should consider is what type of business you have. This will help you determine exactly what level of commercial grinder you’ll need. Ultimately, if you aren’t planning on selling coffee for the majority of your business’s income, then you won’t need the fanciest commercial level grinder. If you’re looking for a coffee grinder simply for home brewing or just for the work office, then you can easily buy a simple conical burr grinder for your kitchen.
However, if you’re running a business such as a restaurant, cafe, or coffee shop, then having a higher quality grinder will create high-quality your coffee–especially espresso.
What Volume Will You Be Producing Coffee?
Most coffee shops that need to pull espresso shots at a faster pace will probably need a doser grinder to keep pace while measuring out your grounds. Likewise, more boutique, slower-paced coffee shops will probably want a doserless grinder to make sure that their beans are ground as closer to brewing as possible, ensuring the highest quality flavor and freshness. Businesses like restaurants will enjoy stepped grinders due to their ease and efficiency, and more skilled, independent baristas will enjoy the stepless grinders in order to perfect their craft.
Personal Grinding Preference
Another factor that’s important to consider when purchasing a commercial coffee grinder is what grinding style you’d prefer. Between conical burrs and flat burrs, there is a different result between the coffee grounds, and these differences will determine which method is best for your business. This all really comes down to personal preference, since every trained barista is bound to have a bias on what they may prefer.

Nuova Simonelli G60
Another Nuova that we enjoy, the Simonelli G60 has 60mm flat head burrs that is capable to grind coffee quickly and adequately. It is a stepless grinder, meaning you’ll have an infinite number of grinding adjustments, though the Simonelli has been known to be ideal for espresso brewing, but not as adequate for grinding finely enough for Turkish coffee.
