When it comes to brewing coffee with a Chemex, the grind size of your coffee beans can make all the difference in the flavor and quality of your cup. In this article, we’ll delve into the world of coffee grinding and explore the optimal grind size for Chemex brewing. Whether you’re a coffee newbie or a seasoned aficionado, this guide will walk you through the process of grinding your coffee beans to perfection.
Understanding the Chemex Brewing Method
Before we dive into the world of coffee grinding, it’s essential to understand the Chemex brewing method. The Chemex is a manual pour-over coffee maker that uses a thick glass container with a paper filter to produce a clean and balanced cup of coffee. The brewing process involves slowly pouring hot water over ground coffee beans in the filter, allowing the coffee to drip into the container below.
The Importance of Grind Size in Chemex Brewing
The grind size of your coffee beans plays a crucial role in the Chemex brewing process. If the grind is too fine, it can lead to over-extraction and a bitter taste. On the other hand, if the grind is too coarse, it can result in under-extraction and a weak flavor. The ideal grind size for Chemex brewing is medium-coarse, which allows for the perfect balance of flavor and body.
Determining the Optimal Grind Size for Chemex
So, how do you determine the optimal grind size for your Chemex? The answer lies in the coffee-to-water ratio and the brewing time. A general rule of thumb is to use a 1:15 to 1:17 coffee-to-water ratio, which means 1 gram of coffee for every 15-17 grams of water. The brewing time should be around 3-4 minutes, depending on the coarseness of the grind and the desired strength of the coffee.
Measuring Grind Size
Measuring grind size can be a bit tricky, but there are a few ways to do it. One method is to use a grind size chart, which compares the grind size to a specific texture or object. Another method is to use a grind size gauge, which measures the grind size in microns. For Chemex brewing, the ideal grind size is around 1000-1200 microns.
Grinding Techniques for Chemex
Now that we’ve determined the optimal grind size for Chemex, let’s talk about grinding techniques. There are two main types of grinders: blade grinders and burr grinders. Blade grinders use a spinning blade to chop the coffee beans, while burr grinders use two abrasive surfaces to crush the beans.
Burr Grinders vs. Blade Grinders
Burr grinders are generally preferred over blade grinders for several reasons. First, burr grinders produce a more consistent grind size, which is essential for Chemex brewing. Second, burr grinders don’t generate heat, which can damage the coffee beans and affect the flavor. Finally, burr grinders are easier to clean and maintain than blade grinders.

Remember to experiment with different grind sizes, use a consistent grind size, and clean your grinder regularly to ensure a consistent flavor. Happy brewing!
What is the ideal grind size for a Chemex coffee maker?
The ideal grind size for a Chemex coffee maker is medium-coarse. This grind size allows for the perfect balance of flavor and body in the brewed coffee. A medium-coarse grind is similar to kosher salt or slightly coarser. If the grind is too fine, it can lead to over-extraction and a bitter taste, while a grind that is too coarse can result in under-extraction and a weak taste.
To achieve the perfect grind size, it’s essential to use a burr grinder, as it produces a consistent grind size. Blade grinders can generate heat, which can damage the coffee beans, and may not produce a consistent grind size. If you don’t have a burr grinder, you can also use a rolling pin or a mortar and pestle to grind the coffee beans, but be careful not to over-grind or under-grind the beans.
How do I adjust the grind size on my burr grinder for a Chemex?
Adjusting the grind size on a burr grinder for a Chemex coffee maker is relatively straightforward. Most burr grinders have a dial or a lever that allows you to adjust the grind size. Start by setting the grind size to a medium-coarse setting, and then adjust it as needed. You can also refer to the grinder’s manual for specific instructions on how to adjust the grind size.
It’s essential to note that different burr grinders may have slightly different grind size settings, so it may take some trial and error to find the perfect grind size for your Chemex. You can also use the “listen and feel” method to adjust the grind size. Listen to the sound of the grinder and feel the grind size by rubbing it between your fingers. A medium-coarse grind should have a smooth, even texture and a sound that is similar to sandpaper.
Can I use pre-ground coffee for a Chemex?
While it’s technically possible to use pre-ground coffee for a Chemex, it’s not recommended. Pre-ground coffee can sit on a shelf for weeks or even months, losing its flavor and aroma. Freshly grinding the coffee beans just before brewing is essential for optimal flavor and aroma. Pre-ground coffee may also be ground too fine or too coarse, which can affect the flavor and body of the brewed coffee.
If you don’t have a burr grinder, it’s better to grind the coffee beans just before brewing using a rolling pin or a mortar and pestle. This will ensure that the coffee is freshly ground and has the optimal flavor and aroma. If you do decide to use pre-ground coffee, make sure to store it in an airtight container and use it within a few days of opening.
How much coffee should I use for a Chemex?
The amount of coffee to use for a Chemex depends on personal preference, but a general rule of thumb is to use 1 tablespoon of coffee for every 6 ounces of water. This is equivalent to about 30-40 grams of coffee for a 6-cup Chemex. You can adjust the amount of coffee to your liking, but this is a good starting point.
It’s also essential to note that the type of coffee beans you use can affect the flavor and body of the brewed coffee. Lighter roasts tend to be more acidic and have a lighter body, while darker roasts are more bitter and have a heavier body. Experiment with different coffee beans and ratios to find your perfect cup.
How do I grind coffee beans for a Chemex if I don’t have a burr grinder?
If you don’t have a burr grinder, you can still grind coffee beans for a Chemex using a rolling pin or a mortar and pestle. Simply place the coffee beans in a plastic bag or between two sheets of parchment paper and roll over them with a rolling pin until they reach the desired grind size. Alternatively, you can use a mortar and pestle to grind the coffee beans.
Grinding coffee beans without a burr grinder can be a bit more time-consuming and labor-intensive, but it’s still possible to achieve a good grind size. Be careful not to over-grind or under-grind the beans, as this can affect the flavor and body of the brewed coffee. It’s also essential to grind the coffee beans just before brewing to ensure optimal flavor and aroma.
Can I grind coffee beans for a Chemex ahead of time?
While it’s technically possible to grind coffee beans ahead of time, it’s not recommended. Grinding coffee beans releases the coffee’s natural oils and flavors, which can evaporate quickly. Grinding the coffee beans just before brewing ensures that the coffee has the optimal flavor and aroma.
If you do need to grind coffee beans ahead of time, make sure to store them in an airtight container to preserve the flavor and aroma. It’s best to grind the coffee beans no more than 30 minutes before brewing, and ideally just before brewing. This will ensure that the coffee has the best possible flavor and aroma.
How do I store ground coffee for a Chemex?
Storing ground coffee for a Chemex requires careful attention to detail to preserve the flavor and aroma. If you need to store ground coffee, make sure to store it in an airtight container, such as a glass jar or a plastic container with a tight-fitting lid. Keep the container away from light, heat, and moisture, as these can affect the flavor and aroma of the coffee.
It’s also essential to use the stored ground coffee within a few days of grinding. Ground coffee can lose its flavor and aroma quickly, so it’s best to use it as soon as possible. If you won’t be using the ground coffee within a few days, it’s better to store the whole coffee beans and grind them just before brewing. This will ensure that the coffee has the optimal flavor and aroma.
