What you will need:
Open a chemex paper filter into a cone shape so that one side of the cone has three layers, and place it into the top of the brewer. The thick (three-layer) portion should cover the pouring spout. Pour a little water on the paper filter to rinse it and heat the Chemex. Discard the water.
Pour the ground coffee into the centre of the cone and lightly shake to level it. Pour about 50 ml of water slowly onto the grounds, starting in the middle working outwards in circular motion. Leave to bloom for 30 seconds. In blooming the grounds expand and releases CO².
Again, in a consistent swirling motion pour the remaining water slowly over the grounds, avoiding direct contact with the paper filter. When brewing is finished discard the paper filter with coffee grounds.
Pour and enjoy
