How To Brew: Chemex

Brew Guides

The principles mentioned in the V60 article also relate to Chemex.

The primary difference between the Chemex and V60 come not only from its unibody glass design but also from the type of paper filter used.

The Chemex filter paper tends to be thicker than the V60, as it is triple bonded. This encourages a slightly larger grind size in order to achieve similar extraction times. Larger grind particles can encourage a more complex extraction giving a high extraction and clarity of flavour (albeit at the expense of a fuller body). 

The Chemex also comes in a larger size than the V60 allowing for brews up to 700mL
