How To Make Coffee Concentrate to Serve Hot Coffee to a Crowd

Strain the coffee concentrate. Place the sieve in the other large bowl or pitcher. Wet the coffee filter and use it to line the sieve. (I use an unfolded Chemex filter paper in these photos. A large filter for urn-style coffee makers would also work.) Carefully pour the coffee and grounds into the sieve, stopping whenever it gets too full. Let sit undisturbed until there is no more liquid dripping through the sieve, which can take 30 to 45 minutes. You will have about 1 quart liquid.
