A Guide to Brewing the Perfect Cup

Prepare For Brewing

Begin to bring filtered water in a kettle to a boil (205°). Pre-Heat the Chemex by pouring heated water over the filter enough to wet it. Swirl the water around and pour out. Add 25-28g of coffee grounds (medium grind) to filter. Shake to level the bed of grounds. Place the Chemex on a scale.

Brew Time


Known as a pristine coffeemaker, Chemex employs all of the chemically correct methods for brewing. Its hourglass shaped flask is made entirely of glass, a chemically inert material that does not absorb odors or chemical residues. The Chemex Glass Coffee Maker has no moving parts and will work forever, unless it is dropped or in some other way demolished.

Bloom & Pour


Start timer. Pour 45g water in 15 seconds, completely wetting the bed of coffee. This is the bloom stage.

Pour At 1:00, pour to 200g in 15 seconds.

At 2:00, pour to 300g in 15 seconds.

At 3:00, pour to 390g in 15 seconds.


Drip should be complete around 4:00. Discard the filter and grounds. Swirl coffee around before pouring out. Serve & Enjoy!

Brewing Tips

After wetting the filter and pouring water out, make sure the filter is still suctioned to the walls of the Chemex with no air pockets.

Place Filter In Chemex with the 3 layer side against the pour spout.

Pour in a circular motion avoiding the edges of the filter. Aim to submerge all dark spots to ensure all of the grounds are saturated.

Grind Adjustment

We recommend using a manual burr grinder. If your resulting cup is too strong and/or bitter, adjust your grind slightly coarser. If it is too weak and/or sour, adjust slightly finer.
