Eight Cup ChemAer™ CHEMEX®
What started as an idea sparked by interaction with the Specialty Coffee community, became a reality when we collaborated with our overseas partner in the development of the ChemAer™, a coffeemaker and aerator combined. This brewer offers an additional design feature to explore the nuances and flavors of the coffee after extraction. A unique and fun tool geared towards anyone who enjoys a good coffee experiment along with a great cup of coffee.
By swirling brewed coffee against the paddles formed into the side of the ChemAer™, the agitation brings more oxygen into the liquid and cools the temperature. Doing this changes to flavor beyond the initial extraction, which is where the experimentation comes in! Try it on all types of roasts, swirl to the left or swirl to the right, have fun and see where to journey leads you.
The ChemAer™ was developed in collaboration with Trendglas and Hungarian Barista champion Attila Molnár. The goal was to create a product which offered an additional option for brewing coffee, one where anybody can enjoy the experience of experimenting with flavor in an elegant and easy way.
CHEMEX coffeemakers are made from the same high-quality glass used for lab ware. Used along with the scientifically designed CHEMEX bonded filters, our pour over system will remove bad fats, bitterness, acidity and sediments that all other types of filters leave behind. Enjoy the perfect cup of coffee, every time you have it.

How much coffee can I aerate at one time? How much coffee can I brew without aerating?
You can aerate smaller 10oz. - 20oz. batches or brew up to a full 40oz. pot of coffee
How much wine can I aerate at one time?
You can pour up to a standard bottle of 25.4 ounces of wine into the ChemAer to aerate.
What size cups for you use for measurement?
We measure our cup size in 5 ounce increments.
Are the coffeemakers dishwasher safe?
Yes! The glass coffeemakers can be put into the dishwasher once the collar and rawhide are removed. However, to avoid breakage please be sure that the carafe is secure and not bumping up next to any other dishes. You can also hand wash the carafes using this coffeemaker brush.
Why do some carafes have wooden collars while some have glass handles?
This is purely aesthetic differences in the design and does not change the functionality of the coffeemaker.
Can I make less coffee than the size of the coffeemaker?
Yes! You can make up to the ounce amount of the size coffeemaker you have or make less. Just adjust your coffee and water recipe to brew however many cups you would like.
How to Use the ChemAer Coffeemaker
The ChemAer™ can be used to brew either 20 ounces when being used for aeration, or up to 40 ounces when not aerating.
Please follow steps 1-7 and step 9, to brew a pot up to 40 ounces of coffee WITHOUT AERATION.
Please follow steps 1-9 to brew a pot up to 20 ounces of coffee WITH AERATION.
Step 1. Get into the grind
Grind your favorite whole bean coffee to a medium coarse ground.
Step 2. Filter up
Open a CHEMEX Bonded™ Coffee Filter into a cone shape so that one side of the cone has three layers, and place it into the top of the CHEMEX Coffeemaker. The thick three-layer portion should cover the pouring spout.
Step 3. The scoop
Put one rounded tablespoon (approximately 5.3 - 5.5 grams) of ground coffee for every 5 oz. cup into the filter cone. Feel free to use more if you prefer it stronger; our CHEMEX Coffeemaker brewing process eliminates bitterness and acidity.
Step 4. Let it bloom
Once you have brought the appropriate amount of water to a boil, remove it from the heat and allow it to stop boiling vigorously. Pour a small amount of water in a circular motion over the coffee grounds to wet them, and wait for about 30 seconds for the grounds to “bloom”.
Step 5. First pour
After the grounds bloom, slowly pour the water over the grounds while keeping the water level well below the top of the CHEMEX Coffeemaker (a quarter inch or more).
Step 6. Brew on
Slowly pour the remaining water over the grounds, using a circular or back-and-forth motion as you pour to ensure an even saturation of the coffee. If you are aerating do not brew more than 20 ounces of coffee in the pot.
Step 7. Toss the filter
Once the desired amount of coffee is brewed, lift the filter with spent grounds out of the brewer and discard. Our filters are biodegradable and compostable.
Step 8. Aerate
Moderately to vigorously swirl the brewed coffee in the carafe in a circular motion, being careful not to splash it out of the coffeemaker. Begin with 5-10 seconds of swirling and adjust from there. It may take more than one brew to dial in what tastes best for a particular bag of beans. This process is aerating the coffee and changing the flavor of the coffee after extraction.
Step 9. Taste your creation
Pour your freshly brewed coffee into your CHEMEX mug and indulge in the flavor.
