Rinse filter thoroughly with hot water. Pour out rinse water.
Add ground coffee to filter, shake gently to level bed of grounds.
Pour approximately 80 grams of water over the grounds, evenly soaking all grounds. Be careful not to pour directly onto the filter. Allow coffee to sit for approximately 40 seconds.
After allowing coffee to degas for 40 seconds, gently pour additional water on top of the grounds until the level of slurry reaches approximately 1/3 of the way up the cone. Be careful not to pour directly onto the filter
Continue adding water to maintain slurry level until you reach the target brew weight (710 grams). Ideally your coffee will finish brewing between 4:30 and 5:00 minutes.
Dispose of the filter, swirl the coffee around inside the chemex and serve.
