The Complete Guide to Coffee Grinders for Beginner's

Coffee grinding plays a crucial role in the taste and quality of your brew. However, with so many types of grinders available on the market, it can be overwhelming to choose the right one.

This complete guide to coffee grinders for beginners discusses important factors such as heat, static, and grind size that can impact the flavor of your coffee. This guide also explores the differences between blade and burr grinders, high-speed and low-speed grinders, and dosing and non-dosing grinders. Additionally, it compares stepped and stepless grinders, and provides examples of popular models for each type.

By understanding these differences, coffee lovers can make informed decisions when selecting a grinder and achieve a more consistent and delicious cup of coffee. 

Critical Properties to Understand


When you grind coffee beans, the friction caused by the blades or burrs generates heat. This heat can affect the flavor of your coffee, making it taste burnt or bitter. To avoid this, it's important to choose a grinder that doesn't generate too much heat or to grind in short bursts to prevent overheating. You can also cool the beans before grinding or grind them in a cool environment to minimize heat production.


You may have noticed that sometimes when you grind coffee beans, the grounds cling to everything. This is due to static electricity. Static can cause the grounds to stick to the grinder, the container, or even the filter, making it difficult to get a consistent brew. To reduce static, you can try adding a few drops of water to the beans before grinding or tapping the container to release any static build-up.

Grind Size

The size of the coffee granules can greatly affect the flavor of your brew. If the grind is too fine, it can result in a bitter or over-extracted flavor. If the grind is too coarse, the coffee may taste weak or under-extracted. Finding the right grind size depends on the brewing method you're using. For example, a French press requires a coarser grind, while an espresso machine needs a fine grind. Experimenting with different grind sizes can help you find the perfect balance for your preferred brewing method.

Coffee grinding may seem like a small detail, but it can greatly impact the flavor of your brew. Considering several properties such as heat, static, and grind size can help you achieve a more consistent and delicious cup of coffee. So next time you're making your morning cup, take a moment to think about the grinding process and how you can improve it for a better-tasting brew.

Comparing Grind Size for Various Types of Coffee

French Press Coffee

For French Press coffee, a coarse grind size is recommended. This allows the coffee grounds to be steeped in water for an extended period of time without over-extraction, resulting in a strong, full-bodied cup of coffee. A grind size that is too fine can lead to a bitter taste, as the water will extract too much flavor from the beans. It is important to note that a consistent grind size is key for French Press coffee, as any large or small particles can result in an uneven extraction and an inconsistent flavor.

Pour-over Coffee

For pour over coffee, a coarse grind size is also recommended. This allows the water to pass through the coffee grounds at a steady pace, resulting in a clean, smooth cup of coffee. A grind size that is too fine can lead to a slow, uneven extraction and a bitter taste. It is important to use a consistent grind size and to adjust the amount of coffee and water used based on personal taste preferences.

Drip Coffee

Drip coffee typically uses a coarse to medium grind size. This allows the water to pass through the coffee grounds at a steady pace, resulting in a balanced, flavorful cup of coffee. A grind size that is too fine can lead to over-extraction and a bitter taste, while a grind size that is too coarse can lead to under-extraction and a weak, watery taste. It is important to adjust the grind size based on personal taste preferences and the type of coffee being used.


Espresso requires a very fine grind size, almost powdery in texture, to ensure the proper extraction time and pressure. The ideal grind size for espresso should be uniform, fine, and consistent to ensure that the water flows through the grounds evenly. Any inconsistency in the grind size can result in under-extracted or over-extracted espresso shots, which will negatively impact the flavor and quality of the espresso.

The quality of the espresso grind is essential in achieving the perfect espresso shot. If the grind size is too fine, the water will not be able to flow through the coffee grounds and the espresso will become bitter and over-extracted. On the other hand, if the grind size is too coarse, the water will flow too quickly through the grounds and the espresso will be weak and under-extracted. Achieving the perfect grind size for espresso requires precision and practice, and is considered by many to be an art form.

Turkish Coffee

Turkish coffee is known for its extremely fine grind, which is even finer than espresso. The beans are ground into a powder-like consistency, almost like flour. The traditional Turkish coffee grind size is important for the brewing process because it allows for the coffee to be brewed without the use of a filter. The coffee is brewed in a special pot called a cezve, where the grounds are boiled with water and sugar. The fine grind allows for a quick extraction and helps to create the thick, foamy layer on top of the coffee, known as the crema. Because the grind is so fine, it is important to use a grinder that can produce a consistent and even grind size. In Turkish culture, the preparation and serving of Turkish coffee is a sign of hospitality and friendship, and is often accompanied by sweets or other treats. 

What is a Burr Grinder and how does it work? 

Burr grinders are considered to be the gold standard in coffee grinding, offering precise and consistent results. These grinders work by using two revolving abrasive surfaces, or "burrs," to grind coffee beans. One burr remains stationary, while the other rotates against it, crushing the coffee beans between them. The distance between the burrs determines the grind size of the coffee. Burr grinders offer a wide range of grind sizes, from fine to coarse, and are highly adjustable. 

Burr grinders come in two main types: flat burrs and conical burrs. Flat burrs are known for producing a more uniform grind size, while conical burrs are preferred for their ability to retain the flavor and aroma of the coffee beans. Burr grinders are also equipped with various settings and adjustments that allow for more precise control over the grind size and consistency. The result is a high-quality cup of coffee with enhanced flavor and aroma. 

One of the key advantages of a burr grinder is that it produces a consistent grind size, which is essential for making good coffee. A consistent grind size ensures that the water extracts the same amount of flavor from each coffee granule, resulting in a balanced and flavorful cup of coffee. Burr grinders also generate less heat and noise compared to blade grinders, which can impact the flavor of the coffee. 

What is a Blade Grinder and how does it work? 

Blade grinders are a popular and inexpensive alternative to burr grinders. These grinders work by using a spinning blade to chop up the coffee beans, much like a blender. The longer the blade spins, the finer the grind size of the coffee. Blade grinders are often marketed as "coffee mills" or "spice grinders" and are commonly found in home kitchens. 

While blade grinders are more affordable and convenient than burr grinders, they produce a less consistent grind size. This inconsistency can result in over-extraction or under-extraction of the coffee, leading to a less than optimal cup of coffee. Blade grinders also generate more heat than burr grinders, which can impact the flavor of the coffee. The heat generated by the blade can cause the oils in the coffee beans to burn, resulting in a bitter taste. 

Despite their limitations, blade grinders are still a popular choice among coffee lovers. They are easy to use, easy to clean, and can be found in most home kitchens. However, for those looking to elevate their coffee game and achieve a more consistent and flavorful cup, a burr grinder is the way to go. 

High Speed vs Low Speed Coffee Grinders

The speed at which the burrs rotate can make a big difference in the quality of the grind. High-speed burr grinders can be extremely fast, providing the user with greater control over the grind size. They are ideal for those who need to grind large quantities of coffee quickly. However, the downside is that high-speed burr grinders can generate a lot of heat, which can affect the flavor of the coffee. 

On the other hand, low-speed burr grinders are known as the "Cadillac" of grinders. They are preferred by coffee aficionados for their ability to produce a consistent grind without generating too much heat or static electricity. Low-speed burr grinders operate quietly and do not bog down or clog up the motor when grinding extremely finely. They are available with either flat burrs or conical burrs, and they can be either direct drive or gear reduction models. 

Grinders with gear reduction work by connecting a high-speed motor to a system of gearing that slows down the speed of the burrs. This is similar to how a bicycle's gears work to help the rider climb uphill. Although they can be louder than direct drive models, gear reduction grinders are effective at grinding coffee without causing the motor to bog down. 

Direct drive grinders are the most expensive but the best grinders available for home or light commercial use. They feature a low-speed motor that is connected directly to the burrs, allowing them to spin at the same speed. These high-quality motors are built to bear the load with ease, and they rotate at a low RPM, generating very little heat or static electricity. Additionally, they operate quietly, making them an excellent choice for home use.

Dosing and Non-dosing Grinders

Should you choose a dosing or non-dosing grinder? While dosing grinders have the advantage of measuring out a consistent dose of coffee with the pull of a handle, non-dosing grinders are a more straightforward approach. With a non-dosing grinder, the coffee is ground directly into your coffee container or portafilter without any intermediary container. 

Non-dosing grinders, also known as doserless grinders, have a simpler design and are easier to clean since there is no extra container to deal with. Some baristas and coffee enthusiasts prefer doserless grinders because they allow for greater flexibility in adjusting the amount of coffee to be ground for different brewing methods. Additionally, doserless grinders are often more affordable than their dosing counterparts, making them a great option for those on a budget. 

On the other hand, dosing grinders are designed to measure out a specific amount of coffee in each dose. This is useful for those who need to produce a consistent amount of coffee on a regular basis, such as in a busy cafe or restaurant. Dosing grinders also tend to have a more polished, professional appearance and can offer more control over the grind size. 

Dosing grinders can sometimes be a bit more complicated to use. The process of pulling the handle to dispense the ground coffee can be messy, and there is often some leftover coffee that needs to be swept away. Furthermore, dosing grinders may not be as effective at producing a consistent grind size as doserless grinders. It ultimately comes down to personal preference and what works best for your individual needs and brewing style. 

Popular Dosing Grinders

For those in the market for a dosing espresso grinder, there are many great options available. One of the most popular and well-regarded models is the Rancilio Rocky. This grinder has been a favorite of coffee enthusiasts for years due to its durable construction, easy-to-use dosing system, and ability to produce consistently high-quality grinds. The Rocky features a powerful motor, 50mm commercial-grade burrs, and a sturdy metal body that can withstand heavy use in a home or commercial setting. 

Another popular dosing grinder is the Gaggia MDF, which offers a similar level of quality and functionality to the Rocky but at a lower price point. The MDF features 50mm burrs, a convenient dosing system, and a compact design that makes it easy to fit into small spaces. While it may not have all the bells and whistles of more expensive grinders, the MDF is a reliable and effective choice for those on a budget. 

For those looking for a more advanced dosing grinder, the Quamar M80 Timer and Ceado E6X are both excellent options. The Quamar M80 Timer features precise dosing controls, a large capacity bean hopper, and a powerful motor that can grind up to 3 grams per second. It also has a sleek, modern design that will look great in any kitchen or cafe. Similarly, the Ceado E6X offers precise dosing, a large capacity hopper, and a powerful motor, along with the added benefit of low noise levels and a user-friendly interface.

Non-dosing Grinders

One of the most popular non-dosing grinders on the market is the Baratza Encore. This grinder features 40 different grind settings, making it perfect for brewing methods from French press to pour-over. It also features a convenient pulse button for manual grinding and an easy-to-use dial for adjusting the grind size. 

Another popular non-dosing grinder is the Breville Smart Grinder Pro. This grinder boasts 60 different grind settings, as well as a convenient programmable feature that allows you to choose the amount of coffee you want to grind for each brewing method. It also has a digital display that shows the grind size, number of shots or cups, and grind time. 

For those who are looking for a compact and portable non-dosing grinder, the Hario Mini Mill is a great option. This hand-crank grinder is perfect for travelers or those with limited counter space. It may take a bit of effort to grind the coffee, but the resulting grind is consistent and perfect for pour-over or French press brewing methods. 

Stepped vs Steppless Grinders

Stepped grinders have predefined settings that click into place, while stepless grinders have an infinite number of settings that can be fine-tuned to your exact preference. 

Stepped grinders are often preferred by beginners and home baristas who want a simpler and more user-friendly experience. The Baratza Encore and Virtuoso are popular examples of stepped grinders that offer a range of preset grind settings for different brewing methods. These grinders are convenient and easy to use, as you can quickly switch between settings for espresso, drip coffee, and French press. However, the downside to stepped grinders is that the settings may not be precise enough for experienced baristas who want to dial in their grind to the exact level. 

On the other hand, stepless grinders are more suitable for advanced baristas who want complete control over their grind size. These grinders allow you to make small adjustments to your grind size, which is essential when pulling the perfect shot of espresso. Examples of stepless grinders include the Mazzer Mini and the Ceado E37S. These grinders are ideal for espresso enthusiasts who want to experiment with different beans and brewing methods, as they provide the ultimate level of customization. 

One potential drawback of stepless grinders is that they can be more difficult to use, as you need to adjust the grind size manually by turning a dial or knob. It can take some trial and error to find the perfect grind size, but the end result is a perfect cup of coffee tailored to your personal taste. Overall, whether you choose a stepped or stepless grinder will depend on your level of expertise and the amount of control you want over your grind size.


The proper coffee grind can make a world of difference in your morning cup of coffee. By considering the various properties of grinders, such as heat, static, and grind size, and selecting the appropriate type of grinder, coffee lovers can enhance the flavor and aroma of their coffee. Whether you prefer a classic drip coffee, an aromatic pour-over, or a rich espresso shot, selecting the right grinder is essential for achieving a high-quality brew.
