What is a Chemex Coffee Maker?

A Chemex coffee maker is a manual brewing device that was invented in 1941 by Peter Schlumbohm. Its distinctive hourglass shape, made of non-porous borosilicate glass, sets it apart from other coffee makers. The Chemex uses a special paper filter, which is thicker compared to standard coffee filters, resulting in a clean cup of coffee without any sediment or bitterness.

How to Clean a Chemex Coffee Maker

Step 1: Disassemble

The first step in cleaning your Chemex coffee maker is to disassemble all its components. Start by removing the wooden collar and tie from around the middle of the brewer. Then, carefully remove the paper filter and dispose of it. Separate the glass flask from the funnel-shaped top part. Ensure that each part is clean and free from any coffee residue before proceeding to the next step.

Note: Always handle the glass flask and all other parts with care to avoid any damages or breakage.

Step 2: Rinse with Warm Water

Next, rinse all the components with warm water. This helps to loosen any oils or lingering coffee particles. Run water through the glass flask, the funnel, and the wooden collar. Make sure that all surfaces are thoroughly rinsed, leaving no residue behind.

Step 3: Cleaning the Wooden Collar

The wooden collar of your Chemex coffee maker requires special care to maintain its appearance and prevent any unwanted odors. Use a soft sponge or cloth soaked in a mixture of warm water and mild soap to gently wipe the wooden collar. Avoid submerging the collar in water, as it may cause damage. Rinse the collar with clean water and pat dry with a soft towel.

Note: Do not use any harsh detergents or abrasive materials that could harm the wooden collar.

Step 4: Deep Cleaning the Glass Flask

To ensure a thorough clean, you can use a mixture of white vinegar and water or a coffee machine cleaner specifically designed for glass brewers. Fill the glass flask with the cleaning solution and let it sit for a few minutes to dissolve any residue. Swirl the liquid around to reach all areas, including the neck and the spout. Rinse the flask thoroughly with warm water to remove any cleaning solution.

Once all the components are clean and rinsed, it is important to let them air dry completely. Place them in a well-ventilated area, allowing any remaining moisture to evaporate. Once dry, carefully reassemble the Chemex coffee maker. Insert a new paper filter into the top part, attach the funnel, and secure the wooden collar around the middle of the brewer.

Regular Cleaning Routine

To keep your Chemex coffee maker in top condition, establish a regular cleaning routine. Clean it thoroughly after each use to prevent any buildup of oils or sediment. This ensures that each cup of coffee you brew is as delicious as the last.

Use Fresh, Clean Water

For the best-tasting coffee, always use fresh, clean water when brewing with your Chemex. The quality of water can greatly impact the flavor of your coffee, so consider using filtered or bottled water if your tap water has a strong taste or odor.
