In this article, we will delve into the intricacies of how fine to grind coffee for a Chemex, exploring what it is, why it matters, and how to achieve the optimal grind size for this beloved brewing method.
What is Grinding Coffee?
Grinding coffee refers to the process of breaking down whole coffee beans into smaller, more manageable particles. This enables the extraction of flavors and aroma during the brewing process, ultimately resulting in a delicious cup of joe. The grind size determines the rate at which water interacts with the coffee, affecting the overall taste and strength of the brew.
Why Does Grind Size Matter for Chemex?
The Chemex brewing method relies on a combination of immersion and pour-over techniques, utilizing a thick paper filter to produce a clean and crisp cup of coffee. The ideal grind size plays a crucial role in achieving the desired extraction and balance of flavors. Here’s why grind size matters:
1. Extraction Efficiency
The size of the coffee particles directly influences the extraction process. Finer grinds have a larger surface area, allowing for quicker extraction and robust flavors. Coarser grinds, on the other hand, require more time for extraction, resulting in a milder cup. Finding the right balance ensures optimal extraction efficiency for your Chemex brew.
2. Avoiding Over/Under Extraction
If the grind size is too fine, the water may have difficulty passing through the coffee bed, leading to over-extraction. This can result in a bitter and overpowering brew. Conversely, using a grind that is too coarse may lead to under-extraction, resulting in a weak and lackluster cup. Identifying the ideal grind size helps achieve a well-balanced extraction, bringing out the best flavors and subtle nuances in your coffee.
3. Filter Functionality
The Chemex’s thick paper filter is designed to remove any sediment or oils from the coffee, yielding a clean and visually appealing brew. The grind size affects how well the filter performs its function. Too fine, and the filter may clog, causing slow draining and potential flavor issues. Too coarse, and the filter may allow unwanted particles to pass through, compromising the brew’s clarity. Understanding the appropriate grind size ensures optimal filter functionality.
How to Grind Coffee for Chemex: Step-by-Step Guide
Now that we understand the importance of grind size when brewing coffee with a Chemex, let’s explore how to achieve the perfect grind:
Step 1: Start with Whole Beans
For the freshest and most flavorful brew, always begin with whole coffee beans. Select beans that align with your taste preferences and roast level of choice.
Step 2: Invest in a Quality Burr Grinder
A burr grinder is essential for achieving consistent and uniform grind sizes. Unlike blade grinders, which can produce uneven particles, burr grinders crush the beans, resulting in more precise control over the grind size. Consider investing in a burr grinder for optimal results.
Step 3: Experiment with Grind Sizes
As grind size preferences vary among individuals, it’s crucial to experiment to find your desired balance. Start with a medium grind size and make adjustments from there. Remember to document your settings for future reference.
Step 4: Observe the Water Flow
During the brewing process, carefully observe the rate at which water flows through the coffee bed. If the water flows too quickly, consider a finer grind size. If it flows too slowly, try a coarser grind.
Step 5: Tweak and Refine
Through experimentation and careful observation, continue to tweak and refine your grind size until you achieve the perfect cup of coffee. Remember, each bean and roast will require slight adjustments, so don’t be afraid to adapt accordingly.

FAQs (Frequently Asked Questions)
Question 1: Why is the grind size important when brewing coffee with a Chemex?
Grind size plays a crucial role in the flavor extraction process when brewing coffee with a Chemex. The Chemex is a pour-over brewing method that requires a medium-coarse grind size. If the coffee is ground too fine, it can result in over-extraction, leading to bitter and astringent flavors. On the other hand, if the grind is too coarse, under-extraction may occur, resulting in a weak and watery brew lacking depth and complexity. Therefore, achieving the right grind size is essential to create a balanced and delicious cup of coffee using a Chemex.
Question 2: What grind size should I use for a Chemex?
For a Chemex, a medium-coarse grind size is recommended. This means that the coffee grounds should be slightly finer than what you would typically use for a French press but coarser than what you would use for a drip coffee machine. The grind size should resemble coarse sea salt or sand texture. This particular grind size allows water to flow through the coffee grounds evenly, extracting the desired flavors without over or under-extraction.
Question 3: Can I use pre-ground coffee for a Chemex?
While using pre-ground coffee is convenient, it is generally not recommended for brewing with a Chemex. Pre-ground coffee loses its freshness and aroma quickly, resulting in a subpar cup of coffee. It is best to grind your coffee beans just before brewing to maximize the flavor and aroma.
