Different Grind Sizes

Extra Coarse

Extra coarse grind is similar to breadcrumbs in texture. It consists of larger particles that are perfect for cold brew, where the extended brewing time allows for extraction without over-extracting the coffee.


A coarse grind has slightly smaller particles than extra coarse. This grind size is commonly used for French press brewing, where a metal mesh filter allows the grounds to steep in water without passing through into the final cup.

Medium Coarse

Medium coarse grind is coarser than table salt but finer than coarse sand. It is often recommended for pour-over brewing methods, such as the Chemex or Hario V60. The medium coarse grind strikes a balance between extraction rate and flavor clarity, allowing for a well-rounded cup.


With a consistency similar to sand’s texture, medium grind is versatile and suitable for various brewing methods. It is commonly used in automatic drip coffee makers and provides a balanced extraction and flavor profile.

Medium Fine

Slightly finer than granulated sugar, medium fine grind is ideal for pour-over methods like the Kalita Wave. This grind size allows for a slightly slower extraction, resulting in a cup with more nuanced flavors.


Fine grind has a texture similar to powdered sugar and is commonly used in espresso machines and Moka pots. The fine particles allow for a more rapid extraction, producing a strong, concentrated shot of coffee.

Extra Fine

As the name suggests, extra fine grind has a texture similar to flour or powdered cocoa. This ultra-fine grind size is typically used in Turkish coffee brewing methods, where the coffee is boiled and traditionally served unfiltered.


Turkish grind is the finest of them all, even finer than powdered sugar. This powdery grind is typically achieved using traditional Turkish coffee grinders. The extremely fine particles provide a rich, full-bodied cup of coffee with a velvety texture.

Brewing Methods and Recommended Grind Sizes

French Press

French press brewing requires a coarse grind to prevent grounds from seeping into the final cup. Aim for a grind similar to breadcrumbs to achieve the best results.

Pour Over

Pour-over methods, such as the Chemex or Hario V60, work best with a medium-coarse grind. This grind size allows for controlled extraction and a balanced flavor profile.


Espresso machines necessitate a fine grind to optimize the extraction process within a short brew time. Aim for a grind similar to table salt for a well-rounded and flavorful shot of espresso.


The Aeropress allows for flexibility in grind size, but a medium-fine grind is often recommended. This grind size strikes a balance between extraction time and flavor clarity.

Cold Brew

Cold brew requires a coarser grind to accommodate the extended brewing time. Aim for a grind similar to coarse sand to achieve a smooth and bold iced coffee.

Turkish Coffee

Turkish coffee, known for its unique brewing method, demands an extra fine grind. The powdery texture enables the grounds to dissolve completely during the boiling process, resulting in a velvety cup of Turkish coffee.

Grind Coarseness Adjustments for Flavor Control

Increasing extraction through finer grind

If you find that your coffee lacks depth or strength, you can try adjusting the grind size to be finer. A finer grind increases the surface area, allowing for more efficient extraction of flavors and oils from the coffee grounds.

Decreasing extraction through coarser grind

On the other hand, if your coffee tastes overly bitter or astringent, it might be an indication of over-extraction. In this case, adjusting the grind size to be coarser can decrease the extraction rate and create a smoother, less intense brew.

Finding the balance for optimal flavor

Achieving the perfect cup of coffee often involves finding the right balance of flavors that suits your preferences. Experimenting with different grind sizes and adjusting them according to your desired flavor profile is key to achieving optimal flavor in your brew.

Grind Coarseness and Brewing Time

Impact of grind size on brewing time

The grind size directly affects the brewing time of your coffee. Finer grinds have a larger surface area, allowing for quicker extraction. In contrast, coarser grinds have a smaller surface area and require a longer brewing time to achieve optimal extraction.

Avoiding over-extraction or under-extraction

Over-extraction occurs when the coffee is brewed for too long or with a grind size that is too fine. This leads to a bitter and unpleasant taste. Under-extraction, on the other hand, happens when the coffee is brewed too quickly or with a grind size that is too coarse, resulting in a weak and lacking flavor.

Achieving consistency in extraction time

Consistency in grind coarseness is crucial for achieving consistent extraction time. This ensures that each batch of coffee is brewed to the same level of extraction, providing a balanced and predictable flavor profile.
