Mastering the Art of Chemex Brewing: Choosing the Perfect Coffee Beans

Choosing the Best Coffee Beans for Chemex

Coffee is a simple pleasure for so many. Whether starting the day with a morning cup or taking a much-needed break in the afternoon, coffee is a routine for many.

For those who enjoy the art of brewing the perfect cup, the Chemex coffee maker is an excellent choice. However, brewing the perfect cup requires high-quality coffee beans.

In this article, we’ll explore the importance of choosing the right coffee beans for your Chemex and how to choose the best ones for your taste buds.

Importance of Choosing the Right Coffee Beans

The coffee bean you choose is the foundation of your coffee experience. Its origin, roast, and quality all play a part in the final taste and aroma of your brew.

Picking the best coffee beans is essential, especially when brewing with a method like the Chemex. The Chemex is designed to produce a clean and smooth cup of coffee, making the bean selection process even more critical.

So when it comes to Chemex brewing, the coffee beans you select have a significant impact on the final taste.

How to Choose the Best Coffee Beans

There are three essential factors to consider when selecting coffee beans: roast, origin, and quality. The roast level will determine the bean’s flavor profile, and the origin will give a sense of the coffee’s unique taste.

When looking for high-quality beans, it’s best to consider beans from a local coffee roaster. Here are some additional tips for sourcing coffee beans:


Consider the roast: The roast level depends on personal preference. That being said, lighter roasts tend to offer a brighter and more lively flavor profile, while darker roasts lean toward a caramelized taste.

For Chemex brewing, medium roasts bring out the best in the coffee beans. 2.

Check origin: The coffee’s place of origin will give clues to its natural taste profile. South and Central American coffee tend to be rich and bold, while African coffee has a more complex and fruity flavor.

3. Look for specialty coffee: Specialty coffee offers higher quality beans, which result in a more flavorful and aromatic cup of coffee.

They are well worth the money.

Recommended Coffee Roast for Brewing with Chemex

When it comes to brewing with a Chemex, a medium roast is the preferred choice. Medium roast coffees allow the coffee’s natural flavors to shine while developing their sweetness and depth in the brewing process.

In contrast, lighter roasts can sometimes be a bit acidic, and darker roasts overpower the coffee’s natural taste profile.

Taste Test of Five Favorite Coffee Origins

Perhaps one of the best ways to understand what type of coffee origin to use is to do a taste test. Based on our research and personal preference, we have put together five favorite coffee origins and their unique taste profile:


Peruvian coffee: This coffee has a distinct aroma of sweet fruit with a slightly nutty aftertaste. 2.

Brazilian coffee: Brazilian coffee has a chocolatey taste, a nutty flavor, and a low acidity level.


Guatemalan coffee: This origin offers an intense flavor with a strong coffee taste. It is sometimes described as a smoky coffee.

4. Ethiopian coffee: Ethiopian coffee is known for its sweet and fruity taste- fresh and zippy on the palate.

5. Costa Rican coffee: This is a balanced coffee flavor with floral notes.


Brewing the perfect cup of coffee starts with selecting the right coffee beans. When it comes to Chemex brewing, it’s best to stick with a medium roast for the best results.

The origin and quality of the coffee beans also play a vital role in the final taste. Experimenting with different coffee origins and doing a tasting to get a sense of what you like best can help pinpoint the perfect coffee bean for your Chemex.

Happy brewing!

Correct Grind Size for Chemex

If you’re someone who values a great cup of coffee, using a Chemex coffee maker might be the perfect choice for you. The Chemex’s unique design and simple brewing process produce a clean, bright, and full-flavored cup of coffee.

However, the final taste of the coffee is highly dependent on the correct grind size. Therefore, this article will cover the importance of correct grind size, recommend a grind size for Chemex, and cover how to adjust the grind size for taste preferences.

Importance of Correct Grind Size

Grinding your coffee beans to the correct size is a critical factor in brewing a great cup of coffee. Each brewing method requires a different grind size to extract the best flavors.

When it comes to brewing with a Chemex, a medium to fine grind gives the best results. If the ground coffee is too large, water will pass through too quickly and the coffee will taste weak.

Conversely, if the grind is too fine, water will not pass through the filter effectively, resulting in a bitter and over-extracted cup of coffee.

Recommended Grind Size for Chemex

The ideal grind size for Chemex brewing is medium to fine. This grind size provides a balance between the coffee’s natural flavors and the extraction process.

Grind the coffee beans as fine as table salt, but not as fine as powdered sugar. A good rule of thumb is to grind the beans to an 18:1 grind size, which means that for every gram of coffee, add 18 grams of water.

Additionally, to achieve the best taste, purchase a high-quality coffee grinder for consistent results.

Adjusting Grind Size for Taste Preferences

If your coffee tastes sour, it might be due to a large grind size. A sour flavor indicates that the water has passed through the coffee too quickly, leaving a lack of flavor.

In this case, adjust the grind size to a finer setting, giving the water more time to extract the coffee’s flavor. If the coffee tastes bitter, the grind size might be too small.

A bitter taste is often a result of the coffee being over-extracted, and adjusting the grind size to a coarser setting should help. Always adjust the grind size incrementally, testing each adjustment until you achieve the desired flavor.

How to Make Chemex Coffee

Using the Chemex for Pour-Over Coffee

Making coffee using a Chemex coffee maker is simple and straightforward. The coffee drips through a paper filter and into a carafe, which eliminates coffee sediment and produces a clean taste.

Here are the steps to make Chemex coffee:

1. Heat water to between 195F and 205F.

2. Grind the coffee beans to medium-fine consistency.

3. Fold your Chemex filter, and place it inside the top of the Chemex, with the folded side against the spout.

4. Pour hot water over the filter to wet the paper and preheat the unit.

5. Add coffee grounds to the filter, making sure it’s evenly distributed before you brew.

6. Add hot water to the ground coffee, starting in the center and moving outwards.

Slowly pour the water in a circular motion, allowing it to saturate the entire coffee bed. Pause briefly when the water reaches the top of the coffee bed before continuing.

7. Wait for the coffee to brew.

It should take between 3-4 minutes. 8.


Ratio of Coffee to Water for Chemex

The ratio of coffee to water will vary depending on personal taste preferences and the coffee beans’ quality. A general rule of thumb is to use a ratio of 1:16 or 1 gram of coffee for every 16 grams of water.

However, you can adjust the ratio according to the type of roast and your preference. If you prefer a stronger coffee, consider using a 1:14 coffee to water ratio.

On the other hand, a 1:18 ratio will produce a weaker coffee.

Difference Between Pour-Over Coffee and Other Coffee Brewers

The main difference between pour-over coffee and other coffee brewing methods is the control of the brewing process. With fabric filter coffee makers or drip coffee machines, the water and coffee come into contact for a more extended period, which can over-extract the coffee’s oils, producing a slightly bitter taste.

Pour-over coffee, such as Chemex, allows greater control over the brewing process, resulting in a cleaner and tastier cup of coffee. In conclusion, making the perfect cup of coffee using a Chemex requires attention to detail, starting with the correct grind size and coffee to water ratio.

A medium to fine grind size is recommended, but the ideal size depends on personal taste preferences. Experimenting with different grind sizes and coffee to water ratios is an excellent way to learn how to make an exceptional cup of Chemex coffee.

So, enjoy the process and perfecting your coffee craft.
