Step 1

Coarsely grind the coffee: Grind the coffee beans on the coarsest setting on your grinder, or in short 1-second pulses in a spice grinder. The grounds should look like coarse cornmeal, not fine powder. You should have just under 1 cup of grounds.

Step 2

Combine the coffee and the water: Transfer the coffee grounds to the container you're using to make the cold brew. Pour the water over top. Stir gently with a long-handled spoon to make sure the grounds are thoroughly saturated with water.

Step 3

Steep overnight: Cover the jar with a lid or a small plate to protect it from dust and bugs. Let the coffee steep for about 12 hours. The coffee can be left on the counter or refrigerated; steeping time is the same.

Step 4

Strain the coffee: Line a small strainer with cheesecloth or flour sack cloth and place over a large measuring cup or bowl. Pour the coffee through the strainer.

Step 5

Store the coffee: Transfer the coffee to a small bottle or jar and store in the fridge for up to a week.

Step 6

Serve the coffee: Dilute the coffee with as much water or milk as you prefer. Serve over ice or warm for a few minutes in the microwave.
