Question: how much coffee to use for 6 cup chemex?
Answer: It's a good idea to warm your cups with some hot water too. Grind 25g (for 3 Cup Chemex) 44g (for 6 Cup Chemex) of coffee and place it in the filter. Gently tap the Chemex on the bench to settle the grounds into a flat bed. Gently pour in 40g (for 3 Cup Chemex) 80g (for 6 Cup Chemex) water, just off the boil.
