How to Make It
Combine coffee grounds and cold water in a large container with a tight-fitting lid. Stir gently, cover, and let sit for 12-24 hours (we let ours sit for 16 hours).
When cold brew has steeped for an adequate amount of time, pour the mixture through a mesh sieve lined with a double layer of cheesecloth. If cold brew looks murky, you may want to pass it through clean cheesecloth 1-2 more times until no sediment remains.
When cold brew concentrate is ready, mix with 1-2 parts cold water or milk and enjoy!
