ChemexClassic Series, 6-Cup.
The verdict in one line: Chemex's own spec sheet confirms a single-vessel, 30 ounce borosilicate glass brewer built around a 5 fl oz cup and proprietary Bonded filters, numbers that satisfy our pour-over guide's rinse step and near-boiling heat needs but don't match its named V60 dripper or its 250 g gram-based scaling.

For you if
- You want a single borosilicate glass vessel that is both the dripper and the server, unlike our guide's separate dripper-plus-server gear lines (Chemex's own dimensions and material listing).
- You're comfortable converting our guide's 15 g to 250 g gram scaling yourself: Chemex's own instructions measure by the tablespoon against a 5 oz. cup, not grams.
- You want a brewer body rated for the near-boiling water our guide calls for at contact: Chemex states the vessel is high quality, durable borosilicate glass.
- You already use, or are ready to buy, Chemex's own Bonded filters: our guide's rinse step and FAQ both explicitly cover Chemex filters alongside V60's.
Not for you if
- You want the exact dripper named in our guide's gear list: it specifies a Hario V60 dripper and paper filters, and this is a different brewer, Chemex's model CM-6A.
- You're brewing to our guide's precise 250 g per-cup water target: Chemex's own cup measure is 5 fl oz per its listing, a smaller unit, so the printed 6-Cup rating does not confirm six of our guide's servings.
- You want a universal paper filter: this brewer requires Chemex's own Bonded filters, sold separately from the coffeemaker.

Questions, answered plainly
FAQ.
Chemex’s own product page lists the Classic Series 6-Cup as model CM-6A, a 30 ounce, high quality and durable borosilicate glass vessel measuring 8 1/2 inches tall and 5 1/8 inches in diameter, sold with a polished wood collar and leather tie. It uses Chemex’s own Bonded filters, sold separately under the codes FP-1, FC-100, FS-100 and FSU-100. Our pour-over guide’s gear list names a “Hario V60 dripper and paper filters” as the brewer its method is written around, so this is a different, single-vessel brewer, not the one the guide’s five-pour, ribbed-cone steps assume.
That single-vessel design cuts both ways against the guide’s own gear list. Where the guide separately calls for a dripper and a “server or mug to brew into,” the Chemex CM-6A is both pieces in one, satisfying that second line by design. But the guide’s scaler runs in grams, 15 g of coffee to 250 g of water per cup, holding the same ratio at any scale. Chemex’s own instructions measure differently: one rounded tablespoon of ground coffee for every 5 oz. cup. Espresso Parts’ listing confirms that 5 oz. equals one Chemex cup, a smaller unit than our guide’s 250 g per-cup target, so the printed 6-Cup, 30 ounce capacity does not confirm six servings sized to our guide’s recipe.
Two things do line up. The guide’s prep step rinses the paper filter with hot water before brewing, and its FAQ specifically names Chemex filters alongside V60’s as needing that same rinse to seat properly, a match this borosilicate vessel and its Bonded filters satisfy directly. And the guide’s pour step calls for water fresh off the boil, 90 to 96C, in contact with the bed for the length of the brew, a temperature range Chemex’s stated borosilicate glass construction is built to handle.
FAQ
How many of our guide’s cups does the 6-Cup Chemex hold?
Chemex’s own capacity is 30 ounces, and Chemex states 5 fl oz equals one of its own cups on this brewer, per Espresso Parts’ listing. Our pour-over guide’s cup is 250 g of water, a larger unit than Chemex’s own 5 fl oz cup, so the printed 6-Cup rating on this brewer does not confirm six of our guide’s servings.
Is this the dripper our pour-over guide is written for?
No. Our guide’s gear list names a Hario V60 dripper and paper filters specifically. This dossier verifies the Chemex Classic 6-Cup, model CM-6A, a different, single-vessel brewer that combines the funnel and the carafe in one piece of borosilicate glass.
Does this brewer need special filters?
Yes. Chemex states this coffeemaker uses its own Bonded filters, FP-1, FC-100, FS-100 and FSU-100, sold separately from the coffeemaker; these are not interchangeable with V60-style filters. Our guide’s rinse step and FAQ both call out Chemex filters by name alongside V60’s, so the same hot-water rinse before brewing applies here too.
What’s included with the Classic 6-Cup?
Chemex’s product page lists a polished wood collar with a leather tie included with the glass vessel. The Bonded filters are sold separately.
Can this brewer handle the near-boiling water our guide calls for?
Our guide calls for water fresh off the boil, ideally 90 to 96C (195 to 205F), at contact through the brew. Chemex states the vessel is made of high quality and durable borosilicate glass, a material used specifically for resistance to near-boiling liquid contact.
