Line your Chemex with a filter and wet the filter with hot water. Drain the water from the bottom. Measure 33 grams (roughly the height of the wooden collar) of coarse ground coffee into your filter-lined Chemex.
In a spiral motion, pour enough boiling water over the grounds to wet them. Wait 30 seconds for the coffee to “bloom” (release gas). Pour boiling water in a controlled spiral motion, waiting once or twice to keep the basket from overflowing, until the coffee reaches the dimple on the base of the Chemex. If using a natural filter, compost your grounds and enjoy your coffee!
