Unleashing the Flavors of Chemex: A Guide to Brewing the Perfect Cup

If you’re a coffee enthusiast who is always looking for a new brewing method, the Chemex is a must-add to your brewing arsenal. This manual pour-over style coffeemaker has been around since the 1940s and continues to capture the hearts of coffee lovers with its great tasting and subtle brew.

In this article, we’ll take a closer look at the Chemex, its importance to coffee taste, and what you need in your arsenal to brew the perfect cup of Chemex coffee.

Background Of The Chemex

The Chemex was invented in 1941 by a German chemist, Peter Schlumbohm, who was determined to bring a new brewing experience to coffee lovers. It has since become a favorite among coffee connoisseurs due to its unique design and unparalleled brewing experience.

The Chemex is a manual pour-over style coffee brewer made from non-porous, heat-resistant borosilicate glass. It comes in various sizes, ranging from 3 cups to 10 cups, and requires a special type of filter paper created specifically for the Chemex.

These filters are thicker than typical coffee filters, which means they can separate more oils and sediment from the coffee.

Importance Of Chemex Coffee Taste

The taste of Chemex coffee is one of the many reasons why coffee enthusiasts flock to this brewing method. The Chemex’s unique design has a knack for producing a balanced, subtle, and great-tasting coffee due to its slow coffee extraction process that allows the coffee flavors to mix and blend harmoniously.

Unlike French press coffee, which tends to keep all the oils and sediment in the coffee, leading to a more intense coffee tropical flavor, the Chemex filters out these oils resulting in a cleaner and crisper taste.

Equipment List

To start brewing the perfect cup of Chemex coffee, you will need several things besides the Chemex itself, including Chemex filters, coffee beans, a coffee grinder, a scale, and a kettle.

Fresh roasted coffee beans with high-quality standards significantly affect the flavor profile of Chemex coffee. Coffee origins can produce either fruity, spicy, nutty, floral, or chocolatey coffee flavor notes.

It is up to the taste and preference of the coffee drinker to pick the desired flavor profile. Coffee roasts, on the other hand, can result in either a sweet or dark roast, depending on the preferred coffee taste.

Best Coffee Origin for Chemex Coffee

Ethiopian coffee beans possess fruity, floral, and citrus flavors, making them perfect for Chemex coffee. Costa Rican coffee beans, on the other hand, possess nutty, chocolatey, and citrus flavors making them a popular choice for Chemex brewing as well.

Importance of Coffee Roast

Coffee roasting affects the acidity, sweetness, and bitterness of the coffee bean. The perfect roast for Chemex coffee is medium since it highlights the coffee’s natural flavor and profile without overpowering it.

Dark roasted coffee beans are oily and have an intense taste profile, leading to intense and smoky flavors for the final brew.

Specialty Coffee Beans

For coffee enthusiasts, experimenting with specialty coffee beans is a chance to unleash flavor potential and create unique coffee profiles. Specialty coffee beans originate from specialty growers, ensuring the highest standard of taste, quality, and production technique.

Brewing Guide for Chemex

Brewing coffee with a Chemex can be a complex process, but it’s worth the effort when you taste the coffee’s clean and crisp flavor notes. Here is a step-by-step guide to brewing the perfect cup of Chemex coffee.

Grind Size and Boiling Water

To start, you will need to grind your coffee beans to medium-fine. Then, heat filtered water to boiling point, and let it cool slightly, until it hits a temperature range of 195-205F.

Boiling water burns the coffee ground, leading to an undesired taste.

Blooming and Pouring Water

Place the filter paper in the Chemex and pour hot water over it. This process ensures that the paper filter sticks to the Chemex walls and preheats the Chemex.

Discard the hot water, add the coffee ground, and then, create a small well-like depression in the coffee ground. Pour a small amount of hot water (about twice the weight of the coffee) into the well and let the coffee bloom for about 30 seconds.

Water and Coffee Ratio

The water-to-coffee ratio is essential for the perfect extraction. A good starting point for weighing the coffee should be around 1g of coffee per 15-17g of water.

As you get more experienced in Chemex brewing, you can adjust the ratios to achieve your desired flavor profile.

Brew Time and Coffee Bed

Start pouring hot water onto the coffee bed in a circular motion, starting from the center and moving towards the edges. Continue pouring until the Chemex’s desired weight is reached.

Then, let the coffee steep for an additional 3-4 minutes before removing the filter.

Brewing Time, Coffee Bed, and Swirls

Control the brewing time carefully.

A 4-5 minute steeping time on average is ideal for flavor extraction. During this period, avoid stirring the coffee as it will disrupt the coffee bed’s balance.

A quick swirl of the Chemex glass at the 3rd minute mark will allow the coffee to be evenly distributed.

How to Clean a Chemex

A Chemex brewing equipment needs to be cleaned regularly after use to prevent rancid oils and coffee build up. Here’s how to clean a Chemex.

Importance of Cleaning Equipment

Cleaning your equipment is fundamental to maintaining the quality of your Chemex coffee and prolonging the life of your equipment.

Rinsing and Soap

The cleaning process can start by rinsing the Chemex with boiling water, removing any loose coffee grinds. Then, a small amount of soap and a soft brush or a sponge gently scrub off the residue.

Ensure the soap is well rinsed off before using the Chemex again.

Frequency of Cleaning

Chemex should be cleaned at least once a week, or after each use as some coffee grounds may be difficult to clear.

Different Ways to Clean

  1. Salt and Ice Method – This method involves pouring coarse-level salt and ice cubes into the Chemex. Swirling the mixture in the Chemex knocks the sediments off the filter.

  2. Dishwasher Method – Unconventional but safe method of cleaning the Chemex.

    The Chemex should be placed on the top rack of the dishwasher for the cleaning process.

  3. Vinegar Method – The acidic nature of vinegar is useful in removing stale coffee oils. Combine water and apple cider vinegar to create a mixture poured into the Chemex and left for a few minutes before rinsing off.

  4. Baking Soda Method – An environmentally sustainable method of cleaning the Chemex involves using baking soda for scrubbing the glassware surfaces and getting rid of rancid coffee oils.

  5. Specialized Cleaner – Specialized cleaning products offer specific cleansing agents for removing coffee oils and sediments.


In conclusion, brewing coffee with Chemex is an enjoyable experience that requires careful attention to the equipment’s equipment list, grind size, and water temperature. Proper cleaning and maintenance of the Chemex equipment prevent rancid oils and coffee build-up, prolonging the equipment’s lifespan.

Cleaning methods include rinsing with boiling water and soap, salt and ice method, vinegar method, baking soda method, and using specialized cleaner products.
