Brewing Tip № 1: When placing the filter in the chemex, be sure to have the side with three layers against the spout. After rinsing the filter, pour the rinse water out of the side opposite the spout. Check to make sure the filter is still suctioned to the wall of the cone, with no air pockets.
Brewing Tip № 2: When pouring, you should look for dark spots on the surface of the slurry. Target your pour to submerge these spots which ensure that all the coffee in the cone is saturated. When this is achieved, continue the pour directly in the middle to agitate the slurry.
Grind Tip: All grinders will produce a mix of course and fine particles – none are perfect, however, burr grinders produce far more uniformity. If your resulting cup is too strong and/or bitter, adjust your grind slightly courser. If it is too weak and/or sour, adjust slightly finer.
