Step 1

Place ground coffee and water in a quart size mason jar or other container. Stir to combine, or seal the lid and shake gently.

Step 2

Let the mixture steep for 12-18 hours at room temperature or in the refrigerator.

Step 3

Place a fine mesh strainer over a liquid measuring cup or other container. It is easiest if you strain the coffee into something with a pour spout so that you can transfer it to a mason jar for storage. Line the strainer with a few layers of cheesecloth or a nut milk bag.

Step 4

Pour the cold brew through the strainer and let all of the liquid strain through.

Step 5

Store cold brew in an airtight container in the refrigerator for up to one week. To serve, dilute the coffee concentrate to your desired strength. I use equal parts coffee concentrate and water. Serve with half and half or milk, as desired.
