Chemex (Wooden Collar Series)

A medium to medium-coarse grind works best for Chemex brewing. The consistency should resemble coarse sea salt. If your coffee tastes bitter or over-extracted, try a coarser grind; if it tastes weak or sour, go finer. Our grind size guide has more detail on dialling in your perfect brew.

The 3-cup Chemex (CM-1C) uses half moon filters (FP-2 or FP-2N). The 6-cup, 8-cup and 10-cup models all use the larger square or circular filters (FS-100, FC-100, FSU-100 or FP-1). Filters are sold separately and you can browse our full range of Chemex filters on site.

A typical Chemex brew should take between 3.5 and 4.5 minutes from the first pour to the last drop. If it's draining too quickly, your grind may be too coarse; if it's taking much longer, the grind is likely too fine.

The Chemex can be placed on a glass-top or ceramic stove on a low setting. However, it should never be placed directly on a gas flame or electric coil without a wire grid, as this can cause the glass to crack. For best results, we recommend brewing fresh or using a separate carafe warmer.

Yes, the glass carafe is dishwasher safe. Simply remove the wooden collar and leather tie before washing. The collar can be wiped clean with a damp cloth and should not be submerged in water.

Bleached (white) Chemex filters are oxygen-cleansed for a neutral taste. Unbleached (natural) filters are slightly more environmentally friendly but may impart a subtle papery taste if not rinsed thoroughly before brewing. Both filter types deliver excellent results.

The Chemex Bonded Filters are 20–30% heavier than standard paper filters, removing more oils, sediment and bitter compounds during brewing. Combined with the non-porous borosilicate glass, which doesn't absorb flavours or odours, the result is an exceptionally pure and clean cup.

The "cup" measurements refer to 5oz American coffee cups, not standard mugs. In practical terms, the 3-cup makes roughly one large mug, the 6-cup makes two to three mugs, the 8-cup makes three to four mugs, and the 10-cup makes four to five mugs.

Absolutely. The Chemex works beautifully for loose-leaf tea. Simply place the tea leaves in a rinsed filter and pour hot water over them as you would with coffee. The result is a clean, sediment-free brew.
