15 Terms That Everyone Who Works In Coffee Machine Grinder Industry Should Know
Coffee Makers With a Built-In Coffee Machine Grinder

Anyone who is a dedicated java enthusiast knows that getting the perfect cup takes many steps, and the motivation to complete them on an early hour is usually low. Coffee makers with a built-in grinder take the guesswork out of the process, removing the necessity of measuring and grinding beans in advance.

How to Grind Coffee

If you're looking to make the best-tasting coffee, you should grind your beans prior to the coffee is brewed. Grinding your beans alters the size of the particles and also increases the surface area, which makes it easier for water to mingle with and extract flavors from the coffee. The length of time you have between grinding and brewing impacts the quality of your coffee: If you grind beans ahead of time, they can quickly begin to oxidize, ruining the flavor.

The type of grinder you select can affect how coffee is ground. Burr grinders and Blade grinders are the two main types. Burr grinders consist of rotating burrs which grind beans into tiny, uniform particles. They're generally quieter than blade grinders and offer more consistency.

Blade grinders, made up of propeller-like blades that cut the beans into smaller chunks, are available. They are generally louder than burr grinders and less consistent, but are a less expensive alternative.

It's important that you only grind the amount of coffee you require at any given moment. Some grinders have hoppers with different capacities, which affect how many cups or shots can be ground simultaneously. Different grinders may require different amounts of effort to adjust the grind size.

If you're using a grinder with burrs you can alter the size of the ground particles by turning a collar at the top of the grinder, which can move the burrs closer or further apart. You can also play around with the settings to find the one that is suitable for your brewing process.

Depending on your brew method it's likely that you'll need to test various grind sizes before you find one that tastes good. There are some suggestions from coffee experts and manufacturers however it's up to you to discover the right blend of flavor and size to suit your personal taste. You might have read that a French Press works best with coarsely-ground coffee, or that espresso requires fine-ground coffee. But, those suggestions aren't necessarily accurate: Different Brewers require different amounts of heat and water to extract the flavors they produce.

Burr Grinders

A burr grinder is comprised of two interlocking pieces--one stationary and the other rotating. Both have sharp edges that crush the beans as they move through. This gives you precise control over the size of your beans which is an essential element for many methods of brewing. It also produces less heat than blade-grinders which preserves the flavor of your coffee.

There are two primary kinds of burr grinders: flat and conical. Conical burrs are conical rings with serrated edges. They grind against each other to create a fine-to-medium grind. They are available in the majority of home grinders. burr mill grinder on the other hand, come with two identical rings with serrated edges that grind against eachother for a fine to medium grind. They can be found in a few of the larger commercial grinders.

The two types of burr grinders differ in their geometry, which ultimately affects the distribution of grind sizes produced. They also run at different speeds, which may alter the taste of your coffee. A good burr grinder operates at a slower speed that means it produces less heat and static. A less expensive grinder will spin at a faster rate. This could cause the burrs get stuck together and leave behind a smudge that could affect the subsequent batches.


Both kinds of burr grinders may be made from metal, ceramic or a combination of both. Metal burrs tend to be more durable and less prone to damage. Ceramic is more fragile, and may chip and crack if they come into contact with small rocks or other particles.

The majority of people opt for grinding machines with burrs since it creates a consistent, uniform grinding. It can take a while to achieve the right consistency and you may need to adjust the settings on your grinder as it runs. After each use, clean the machine to eliminate leftover beans or overly roasted ones that may have gotten trapped between the burrs.

The temperature of the water used to brew your coffee may also influence the granules. If the water is too hot, it can cause the granules to burn and alter their flavor. The ideal temperature for brewing is about 195 degrees Fahrenheit.

Blade Grinders

As the name suggests these grinders use the spinning of a blade to chop the beans. They look like mini blenders and are popular because of their lower cost and smaller size. They are also good for those who do not plan to drink coffee black, but would like to add sugar or other flavors.

The issue is that blade grinders can't produce a consistent grind size. The blades' chopping motion chops coffee beans into smaller pieces while others are cut into larger pieces, creating an uneven mixture that can vary in size from coarse to fine. The uneven distribution of sizes could lead to an overor under extraction of the coffee beans which will ultimately alter the flavor of the final cup.

The whirling action can cause the beans to be burned in the process of grinding. This can alter the flavor of the coffee because burned beans have less surface area for hot water to interact with and extract.

Blade grinders can also produce more dust while in use. This is an issue in kitchens that are packed. This dust can be an ill-health risk since it may contain harmful microbes that can infect the final coffee. Additionally, blade grinders can be difficult to clean due the sticky residue that they leave behind after each use.

Contrary to burr grinders, they rely on two rotating surface abrasives to crush beans into a uniformly consistent ground size. The burr grinders can do this without the use of adjustable settings. This allows the user to select the exact size of grind based on the brewing method. The consistent grind enables water to pass through the grounds in a uniform way, resulting in a more uniform extraction of the coffee's flavor. Burr grinders are more expensive and can require more maintenance than blade grinders, however. Before making a decision be sure to consider your budget and brewing techniques as well as the counter space you have available. It could be worth the extra cost to go with the burr grinder.

Dosing Grinders

Like its name implies, a dosing grinder is a type of coffee grinder that is designed to grind only the amount of coffee required for brewing. This is a well-liked type of grinder for home use since it eliminates the need to store ground coffee in between uses, and makes sure that the beans are fresh when brewed. This will help achieve the highest flavor extraction from coffee and can also reduce waste.

The grinder is equipped with an internal chamber which is used to collect the coffee ground and store it until it is dispensing through the portafilter. It is typically situated at the top of the body of the grinder and comprises six sections that are evenly sized. When the coffee is removed from the burrs of grinding, it is deposited into one of the sections. A handle can be pulled which controls the speed at which the sections move. As the sections are rotated, the ground coffee is then dispensed into the portafilter.

There are a few grinders that can accomplish this successfully. They are generally the most effective in terms of quality and consistency. (Titan class). There are many grinders that aren't efficient at this, and may produce inconsistent results or overfill your portafilter. This is why we recommend using a dedicated single dosing grinder for espresso, if you can, and for other brewing methods, it is recommended to be able to calculate the amount of coffee that is needed.

Rancilio Rocky and Gaggia MDF are some of the most popular dosing grinders that are available. They're all great choices for home espresso lovers. There is also a single dosing model made by Ceado named the E37SD that has been being talked about in recent times and was recently described as potentially an "Niche Zero Killer". The E37SD features a huge 83mm OpalGlide-coated brew burr that produces constant grinds and virtually zero retention. It can be adjusted to any brewing method.
