Chemex review: the design classic that still brews beautiful coffee

The Chemex is one of the few kitchen objects that sits in a museum and on the breakfast table at the same time, and this Chemex review asks whether the Six Cup Classic is still worth buying in 2026. Invented by chemist Peter Schlumbohm in 1941, the hourglass-shaped glass brewer with its wooden collar has changed very little. It is made in Massachusetts and is part of the permanent collection of the Museum of Modern Art in New York.

This review draws on Chemex's own specifications, independent tests by Serious Eats and Tom's Guide, and a large base of owner feedback. We cover taste, the famous bonded filters, sizes and models, cleaning, fragility and how the Chemex compares with the Hario V60.

Design: lab glass meets mid-century style

The Chemex is a single piece of borosilicate glass, the same type used for laboratory ware, shaped like a flask with a conical top. A polished wooden collar tied with a leather strip acts as an insulated handle. There is a channel in the spout that lets air escape and makes pouring easy.

The Six Cup Classic stands 8.5 inches tall and is about 5 inches wide, compact enough for most cupboards. Chemex also makes Glass Handle versions without the wood and leather, Handblown models, a ChemAer aeration model and the Ottomatic electric brewer. Serious Eats' large-batch pick was actually the Glass Handle model, which is easier to hold.

Chemex filters: the secret and the catch

Much of the Chemex's character comes from its Bonded paper filters, which the company says are based on laboratory paper. Tom's Guide reports Chemex's claim that they are up to 30% thicker than other brands. They slow the flow and hold back more oils and fines, which is why Chemex coffee tastes so clean. Research summarised on Wikipedia also suggests paper filtering reduces cafestol, a compound linked to higher cholesterol.

The downside is cost and fit. Tom's Guide worked out Chemex filters at around 11 US cents each, pricier than V60 or AeroPress filters, and found cheap generic filters did not fit well and let grounds through. Serious Eats recommends rinsing the thick paper well to avoid a papery taste.

• Pre-folded circles and squares
• Natural (unbleached) or white
• Unfolded half-moon and circle styles

Taste and brewing experience

Independent reviewers are consistent on flavour. Serious Eats praised the clarity and how tasting notes shine through. Tom's Guide found the coffee light, aromatic and free from silt and bitterness, and preferred it to French press and moka pot coffee.

Brewing is straightforward: rinse the filter, add medium-coarse coffee, bloom with a little hot water, then pour the rest in stages. The thick filter means brew times are longer than with a V60, but Tom's Guide found the method easy to master. It also works for loose-leaf tea.

Cleaning, care and durability

Glass does not absorb flavours, so cleaning is easy. Chemex says the carafe is dishwasher safe once you remove the wooden collar and tie, but recommends hand washing with a brush to reduce the risk of breakage. Untying the collar each time is a small chore that Tom's Guide found slightly fiddly.

The glass itself gets hot during brewing, so always hold it by the collar or handle. As with any glass brewer, a knock against a tap or countertop can crack it, which is the main durability risk.

Chemex vs Hario V60

The V60 is far cheaper, gives a little more body and offers more control for single cups. The Chemex is better for brewing several cups at once and yields an even cleaner result thanks to its filters. Tom's Guide, testing both at the same time, found them similar in quality, with the Chemex lighter and more fragrant. Serious Eats picked the V60 as its best overall pour-over and the Chemex as its best for large batches.

Which Chemex size should you buy?

Because Chemex counts a cup as 5 oz, the Six Cup Classic makes about two to three standard mugs, which suits most couples and small households. The 3-cup model is best for one person, while the 8- and 10-cup versions suit larger families or entertaining. If you dislike the leather tie or want an easier grip, choose a Glass Handle model.

Frequently asked questions

More than 80 years after its invention, the Chemex Classic remains one of the most satisfying ways to make filter coffee. It brews clean, fragrant coffee in batches, is easy to use and is a genuine design icon. The pricier filters and fragile glass are the main compromises. If you want pour-over coffee to share, and a brewer you will happily leave on display, the Chemex is worth it.
