Cold brew coffee has become a staple in many coffee lovers’ daily routines. Its smooth, low-acidity flavor and refreshing taste make it perfect for hot summer days. However, achieving the perfect cold brew requires more than just steeping coarse coffee grounds in water. The grind size of your coffee plays a crucial role in the flavor and quality of your cold brew. In this article, we’ll delve into the world of coffee grinding and explore how coarse you should grind your coffee for cold brew.
Understanding Coffee Grind Sizes
Before we dive into the ideal grind size for cold brew, it’s essential to understand the different coffee grind sizes and their uses. Coffee grind sizes can be broadly classified into the following categories:
Extra Fine Grind
An extra fine grind is typically used for Turkish coffee and espresso. This grind size is extremely fine, almost powdery, and allows for a high-pressure brewing process.
Fine Grind
A fine grind is often used for pour-over, Aeropress, and drip brewing. This grind size is slightly coarser than an extra fine grind but still allows for a clean and balanced extraction.
Medium Grind
A medium grind is commonly used for Chemex, French press, and percolators. This grind size is coarser than a fine grind and provides a balanced extraction with a heavier body.
Coarse Grind
A coarse grind is typically used for cold brew, French press, and percolators. This grind size is much coarser than a medium grind and allows for a low-pressure brewing process.
The Ideal Grind Size for Cold Brew
When it comes to cold brew, the ideal grind size is a topic of debate among coffee enthusiasts. However, the general consensus is that a coarse grind is the way to go. But how coarse is too coarse, and how fine is too fine?
The ideal grind size for cold brew is between 0.5 and 1.5 mm in diameter. This grind size allows for the perfect balance of flavor and body. A grind size that’s too fine can lead to over-extraction and a bitter taste, while a grind size that’s too coarse can result in under-extraction and a weak taste.
Why a Coarse Grind is Best for Cold Brew
A coarse grind is best for cold brew for several reasons:
- Low-Pressure Brewing: Cold brew is a low-pressure brewing process that involves steeping coarse coffee grounds in water for an extended period. A coarse grind allows for the perfect balance of flavor and body in this type of brewing process.
- Even Extraction: A coarse grind ensures even extraction of flavors and oils from the coffee beans. This results in a smooth and balanced flavor profile.
- Easy to Strain: A coarse grind makes it easy to strain the coffee grounds from the liquid, resulting in a clean and sediment-free cold brew.
How to Grind Your Coffee for Cold Brew
Now that we’ve established the ideal grind size for cold brew, let’s talk about how to grind your coffee. There are several ways to grind your coffee, including:
Blade Grinders
Blade grinders are the most common type of coffee grinder. They use spinning blades to chop the coffee beans into smaller pieces. However, blade grinders can generate heat, which can damage the coffee beans and result in a poor flavor.
Burr Grinders
Burr grinders are the preferred choice among coffee enthusiasts. They use two abrasive surfaces to crush the coffee beans, resulting in a consistent grind size and a better flavor.
Hand Grinders
Hand grinders are a manual way to grind your coffee. They use a handle to turn a grinding mechanism, resulting in a consistent grind size and a great workout for your arm.
Tips for Grinding Your Coffee for Cold Brew
Here are some tips to keep in mind when grinding your coffee for cold brew:
- Use Fresh Coffee Beans: Fresh coffee beans are essential for a great-tasting cold brew. Try to use coffee beans that have been roasted within the past week or two.
- Grind Immediately Before Brewing: Grinding your coffee immediately before brewing ensures the best flavor and aroma.
- Use the Right Grind Size: As we discussed earlier, the ideal grind size for cold brew is between 0.5 and 1.5 mm in diameter.
- Experiment with Different Grind Sizes: Experimenting with different grind sizes can help you find the perfect balance of flavor and body for your cold brew.
Conclusion
Grinding your coffee for cold brew is an art that requires patience, practice, and a bit of experimentation. By understanding the different coffee grind sizes and the ideal grind size for cold brew, you can create a smooth and refreshing cold brew that’s perfect for hot summer days.

What is the ideal grind size for cold brew coffee?
The ideal grind size for cold brew coffee is a coarse grind. This type of grind allows for the right amount of extraction during the brewing process, which typically takes 12-24 hours. A coarse grind also helps to prevent over-extraction, which can result in a bitter taste.
A coarse grind is similar to kosher salt or slightly larger. If you’re using a burr grinder, you can adjust the grind size to achieve the desired coarseness. If you’re using a blade grinder, you may need to grind the beans in short pulses to avoid generating heat, which can damage the beans.
Why is a coarse grind important for cold brew coffee?
A coarse grind is important for cold brew coffee because it allows for the right amount of extraction during the brewing process. If the grind is too fine, it can lead to over-extraction, which can result in a bitter taste. On the other hand, if the grind is too coarse, it can lead to under-extraction, which can result in a weak or sour taste.
A coarse grind also helps to prevent channeling, which can occur when the water flows too quickly through the coffee grounds. Channeling can lead to uneven extraction and a poor-tasting brew. By using a coarse grind, you can ensure that the water flows slowly and evenly through the coffee grounds, resulting in a smooth and flavorful brew.
Can I use a fine grind for cold brew coffee?
While it’s technically possible to use a fine grind for cold brew coffee, it’s not recommended. A fine grind can lead to over-extraction, which can result in a bitter taste. Fine grinds are better suited for brewing methods that involve hot water, such as espresso or pour-over.
If you only have a fine grind, you can try using it for cold brew, but you may need to adjust the brewing time and ratio of coffee to water. However, it’s generally best to use a coarse grind for cold brew coffee to achieve the best flavor.
How do I grind my coffee beans for cold brew?
You can grind your coffee beans for cold brew using a burr grinder or a blade grinder. Burr grinders are generally preferred because they produce a consistent grind size and don’t generate heat, which can damage the beans. Blade grinders can be used, but you may need to grind the beans in short pulses to avoid generating heat.
When grinding your coffee beans, aim for a coarse grind that’s similar to kosher salt or slightly larger. You can adjust the grind size on your burr grinder or grind the beans in short pulses with a blade grinder to achieve the desired coarseness.
