Chemex Classic pour-over coffee maker, Glass Handle Series

Only the handle and how you hold it. The glass handle gives a cleaner, more minimal look and goes straight in the dishwasher with nothing to remove. The wooden collar and leather tie give the classic look Chemex has carried since 1941, but need removing before the dishwasher. Brewing performance, glass, and filter compatibility are identical across both.

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-1GH) 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.

Our Chemex brew guide covers water temperature, bloom time and pouring technique from start to finish, and pairs well with our grind size guide for dialling in your beans.

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. Because it's one continuous piece of glass, the whole brewer goes straight in the dishwasher with nothing to remove first, unlike the wooden collar model.

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. Rinse either one well and you'll get a clean cup either way.

The Chemex Bonded Filters are 20–30% heavier than standard paper filters. They hold back more oils, sediment and bitter compounds during brewing. Combined with the non-porous borosilicate glass, which doesn't absorb flavours or odours, you get a clean, pure 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 just as well 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.
