How to Grind Coffee for Chemex
Now, let’s dive into the process of grinding coffee specifically for the Chemex. The ideal grind size for the Chemex is medium-coarse, similar to sea salt.
Step-by-Step Grinding Process
Follow these steps to achieve the perfect grind:
1. Measure Your Coffee
A general guideline is to use a coffee-to-water ratio of 1:15 for Chemex brewing. For instance, if you’re using 30 grams of coffee, you should brew it with 450 grams of water.
2. Set Up Your Burr Grinder
Adjust your burr grinder to the medium-coarse setting. If your grinder has specific grind size markings, look for a setting that corresponds to coffee grounds resembling coarse sand.
3. Grind the Coffee
Place the measured coffee beans into the grinder and start grinding. It’s important not to over-grind the beans; stop grinding once most of the coffee grounds reach the ideal size.
4. Inspect the Grind
After grinding, check the consistency. You should have a mix of medium-coarse and similar-sized particles. Avoid too much fine powder, which can lead to over-extraction.
5. Brew Your Chemex Coffee
Once you have your coffee ground to the desired consistency, proceed to brew your coffee using the Chemex. Follow the appropriate brewing time – around four to five minutes – ensuring the grounds are fully saturated and blooming before the drip process begins.
Common Mistakes to Avoid When Grinding Coffee
Even seasoned coffee brewers can fall into several traps, regardless of their experience level. Here are common mistakes to watch out for:
Using Pre-Ground Coffee
While convenient, pre-ground coffee typically results in a less flavorful and aromatic cup. Grinding your coffee fresh ensures you capture those volatile oils and aromas.
Incorrect Consistency
If your grind size is too fine, you risk over-extraction, leading to bitterness. Conversely, if it’s too coarse, the water may pass through quickly, resulting in a weak brew. Always aim for that sweet spot of medium-coarse.
Not Cleaning Your Grinder
Coffee oils can build up in your grinder over time, negatively affecting flavor. Make it a habit to clean your grinder regularly to maintain the best taste.
Optimizing Your Chemex Brewing Technique
Along with grinding, your brewing technique can elevate your coffee experience.
Water Temperature
Use water heated to around 195°F to 205°F (90°C to 96°C) for optimal extraction. Using water that is too cold may not extract full flavors, while boiling water can scorch the coffee.
Brewing Time
The brewing time for a Chemex should be around four to five minutes. Keep an eye on the drip process to avoid over-extraction caused by prolonged exposure to water.
Stirring and Blooming
After adding water to your grounds, gently stir to ensure all coffee is saturated. Allow it to bloom for about 30 seconds before continuing to pour the remaining water.
Storing Your Coffee for Optimal Freshness
To keep your coffee at its peak freshness, follow these storage tips:
Use Airtight Containers
Oxygen is a coffee’s worst enemy. Store your coffee beans in airtight containers to minimize exposure.
Avoid Light and Heat
Light and heat can also degrade coffee. Keep your coffee in a cool, dark place, away from the stove or any heat sources.

What grind size is best for Chemex coffee?
The best grind size for Chemex coffee is a medium-coarse grind. This consistency resembles coarse sea salt and is crucial for optimal extraction during the brewing process. A medium-coarse grind allows water to flow through the coffee grounds at a steady rate, ensuring that the flavors are evenly extracted while minimizing bitterness.
Using a grind size that is too fine can lead to over-extraction, resulting in a bitter taste, while a grind that is too coarse can cause under-extraction, leaving your coffee weak and lacking in flavor. Finding the right balance is key, and experimenting with grind size can help you discover the perfect brew for your taste preferences.
How do I grind coffee for a Chemex?
To grind coffee for a Chemex, start by measuring your coffee beans according to the desired brewing ratio. A common ratio is 1:15, meaning for every one gram of coffee, you should use 15 grams of water. Once you have measured your beans, use a burr grinder for the most consistent grind size. Burr grinders offer precision and can be adjusted to achieve the medium-coarse grind that Chemex requires.
When grinding, make sure to grind only what you need for the brewing session to maintain freshness. After grinding, give the coffee a gentle shake to level the grounds and ensure an even extraction. Properly ground coffee is essential for brewing the best cup and significantly impacts the flavor profile of your coffee.
How much coffee do I need for a Chemex brew?
The amount of coffee you need for a Chemex brew can vary based on personal taste and the size of the Chemex. A general guideline is to use about 1 gram of coffee for every 15 grams of water. For example, if you are brewing a 600-gram batch of coffee, you would need 40 grams of coffee. Adjust this ratio according to your taste preferences—some may prefer a stronger coffee, while others might lean towards a milder brew.
It’s important to scale your coffee and water amounts based on the specific Chemex model you are using. For the 3-cup Chemex, you might use around 20 grams of coffee for a 300-gram brew. Take note that using fresh, high-quality coffee beans will affect the overall flavor, so choose beans that suit your palate.
What is the ideal water temperature for brewing Chemex coffee?
The ideal water temperature for brewing Chemex coffee is typically between 195°F and 205°F (90°C to 96°C). This temperature range is essential for optimal extraction, as water that is too hot can scald the coffee grounds and produce a bitter taste, while water that is too cool may result in under-extraction, leading to a flat and uninspiring cup.
To achieve the desired temperature, you can boil the water and then let it sit for about 30 seconds before pouring it over the coffee grounds. Using a thermometer can help ensure accuracy, but if you don’t have one, a good rule of thumb is to allow boiled water to cool down slightly in the kettle before starting your brew.
Can I use pre-ground coffee in a Chemex?
While it is possible to use pre-ground coffee in a Chemex, freshly ground coffee is highly recommended for the best flavor and aroma. Pre-ground coffee tends to lose its freshness quickly and may not provide the full range of flavors that freshly ground beans offer. If you choose to use pre-ground coffee, ensure that it is ground to a medium-coarse consistency suited for Chemex brewing.
If you must use pre-ground coffee, consider purchasing from a brand that packages their coffee immediately after grinding to maintain freshness. However, investing in a quality burr grinder and grinding your beans just before brewing can significantly enhance your coffee experience, making it a worthwhile effort for any Chemex enthusiast.
