Chemex coffee maker review: an elegant glass brewer that makes very clean coffee for two or more.
Our Chemex coffee maker review verdict up front: the Chemex is one of the best ways to brew clean, bright, sediment-free coffee for two or more people, and it looks beautiful doing it. Its one-piece glass design doubles as a serving carafe, and its thick bonded filters produce an exceptionally clean cup. The tradeoffs are a learning curve with filter folding and grind size, pricier filters, and a fragile glass body.
Below we cover specs and sizes, how the Chemex works, what it does well, its limitations, who should buy it, a reliable brewing recipe, care tips and alternatives.

How the Chemex Works
The Chemex is an hourglass shaped glass vessel. The upper cone holds a folded paper filter and ground coffee; the lower bulb collects the brewed coffee. A groove on one side of the cone acts as an air vent and pouring spout, letting air escape so the coffee drains smoothly. You pour hot water over the grounds in stages, the coffee filters through the thick paper, and you serve directly from the same vessel after removing the filter.
Chemex says its coffeemakers are made from the highest quality borosilicate glass that will not absorb odors or chemical residues. That keeps flavors pure and means the brewer does not take on old coffee tastes over time.
What We Like
Exceptionally Clean Cup
The thick bonded filters are the heart of the Chemex. Chemex describes them as 20 to 30 percent thicker than competing filters, designed to keep bitter elements, oils and grounds out of your cup. The result is clear, crisp coffee with a light body and no sediment, which highlights the delicate flavors of light and medium roasts.
Brews for a Group
The 8 cup model makes about 40 ounces, enough for several people. Because the brewer is also the carafe, you can bring it straight to the table for brunch or guests.
Timeless Design
The Chemex has been a design icon for decades, and many people keep it on display. The glass, wood and leather combination looks at home in any kitchen.
Pure Glass
Non-porous glass does not hold odors or flavors, and you can see exactly how clean it is. Brewed coffee can be covered and refrigerated for later.
Limitations to Know
Learning Curve
Folding the filter correctly, placing the triple layer side against the spout, and finding the right medium coarse grind take a few attempts. If the grind is too fine, the thick filter drains slowly and coffee can turn bitter.
Filter Cost
Chemex bonded filters cost more than standard cone filters, and you need the correct size and shape for your model. Filters are not included with the brewer.
Fragile Glass
Borosilicate glass handles heat well but can break if dropped or knocked. The narrow neck also makes the inside a bit harder to scrub.
Small Batches Are Tricky
Brewing just one cup in an 8 cup Chemex is possible but less consistent, since a shallow coffee bed drains unevenly. Solo drinkers may prefer the 3 cup model or a cone dripper.
Which Size Should You Buy?
Chemex measures cups as 5 ounces. The 3 cup model suits one person, the 6 cup model suits one to three people, the 8 cup model is the most popular for couples and small families, and the 10 cup model suits larger households and entertaining. The 6 cup and 8 cup versions are the most versatile.
Choosing Chemex Filters
Chemex offers bonded filters in white and natural (unbleached) versions, and in pre-folded squares or circles. White filters usually give the cleanest taste. Natural filters are an eco-conscious choice but should be rinsed thoroughly with hot water to remove any papery flavor. The circle bonded filters fit all Chemex coffeemakers except a few small hand-blown models, according to the listing.
How to Brew With a Chemex
- Heat water to about 200°F.
- Weigh and grind about 40 grams of coffee medium coarse, like coarse sand, for 640 grams of water (two to three mugs).
- Place the filter with the triple layer side against the spout. Rinse it with hot water, then pour out the rinse water while holding the filter in place.
- Add coffee and level the bed.
- Bloom with about 80 grams of water, wetting all the grounds. Wait 45 seconds.
- Pour in stages in slow circles, keeping the water level below the rim, until you reach 640 grams.
- Let it drain. Total time should be about 4:00 to 4:30.
- Remove the filter, swirl the coffee and serve.
If brewing takes much longer than five minutes, grind coarser. If it finishes in under three and a half minutes and tastes sour, grind finer. For more techniques, see our guide on how to make pour over coffee.
Who Should Buy the Chemex
The Chemex suits coffee lovers who brew for two or more, enjoy a clean, delicate cup, and appreciate a brewer that doubles as a serving piece. It is a great match for light roasts and specialty single origins.
Skip it if you mostly brew one small cup, prefer a fuller bodied coffee, or want something unbreakable for travel. For a comparison with the most popular cone dripper, read Chemex vs Hario V60, and see more options in our guide to the best pour over coffee maker.
Care and Cleaning
Rinse the Chemex with hot water after each use. For a deeper clean, remove the wooden collar by untying the leather tie, then wash the glass with warm soapy water and a bottle brush. Occasional soaks with a coffee equipment cleaner or a little baking soda remove oily film. Dry and reattach the collar. Avoid sudden temperature shocks, such as pouring boiling water into cold glass straight from the refrigerator.
Chemex Alternatives
If you want a smaller, cheaper brewer with more manual control, the Hario V60 cone dripper is the most popular alternative. If you want a forgiving flat bottom brewer, consider the Kalita Wave. If you prefer more body, a French press or AeroPress delivers a heavier cup. Browse more manual brewers in our French press and pour over section, and pair your brewer with a gooseneck kettle for easier pouring.
Common Chemex Problems and Fixes
- Brew takes more than five minutes: grind coarser, and check that the triple layer side of the filter faces the spout so air can escape.
- Coffee tastes sour or thin: grind slightly finer, use hotter water or extend the bloom.
- Coffee tastes bitter or papery: rinse the filter thoroughly with hot water and avoid over fine grinds.
- Filter collapses into the spout: reposition it with the thick side covering the groove, or press it gently against the glass after rinsing.
- Coffee cools quickly: preheat the glass with hot water, and serve promptly or transfer to a thermal carafe.
Iced Coffee in a Chemex
The Chemex is excellent for Japanese style iced coffee. Place about 260 grams of ice in the carafe, then brew 40 grams of slightly finer ground coffee with about 380 grams of hot water. The hot coffee drips onto the ice and chills instantly, keeping bright, aromatic flavors. Swirl until the ice melts, then pour over fresh ice in glasses. A full Chemex of iced coffee is a great way to serve guests on a warm afternoon.
Coffee That Shines in a Chemex
Because the thick filter produces such a clean cup, the Chemex highlights delicate flavors. Washed light roasts from Ethiopia and Kenya taste floral and fruity, while Colombian and Central American medium roasts show caramel and citrus notes. Dark roasts work too, but they lose some of the heavy body that makes them popular in a French press. Buy beans roasted within the past few weeks and grind them just before brewing for the best results.
Water quality matters as well. Use filtered water that tastes clean, since the Chemex will reveal any off flavors. A water temperature of around 200°F suits most coffees; go slightly cooler for darker roasts.
Chemex vs Automatic Drip Coffee Makers
An automatic drip machine is more convenient: add coffee and water, press a button and walk away. The Chemex asks for about five minutes of attention, but it gives you control over water temperature, bloom and pour speed, and its thick filter produces a cleaner, brighter cup than most drip machines. Many people keep a drip machine for busy weekdays and use the Chemex on weekends or when guests visit. If you want automation with a Chemex style cup, some specialty drip machines are designed to mimic manual pour over, though they cost considerably more.
Serving and Storage Tips
Serve Chemex coffee soon after brewing for the best flavor. If you need to keep it warm, transfer it to a preheated thermal carafe rather than leaving it on a hot stove, which can scorch the flavor and stress the glass. Chemex notes the brewer lets you cover and refrigerate coffee to reheat later without losing flavor, which is handy if you brew a full batch and only drink part of it. Reheat gently and avoid boiling.
How We Evaluated It
This review is based on research rather than in-person trials. We studied the Amazon listings for Chemex brewers and filters, compared the Chemex with cone and flat bottom drippers, and considered how widely it is bought and how owners describe daily use.
FAQs
Is the Chemex worth it?
