Supplies
Mesh Strainer
Cheesecloth
Pitcher, Jar, or Similar Container for Brewing
Scale
Grinder
Coffee
Water (filtered, if possible)
Large Spoon
Ratio
12 oz. of coffee to 3 quarts (.75 gallon) of water
Grid Size
Coarse
Step 1
Weigh or measure the desired amount of coffee. If you don’t have a scale, 1 tablespoon of coffee beans or ground coffee is about 5 grams of coffee.
Step 2
Grind the coffee to a coarse consistency and add the ground coffee to the container for brewing.
Step 3
Measure the desired amount of room temperature water and pour the water into the container over the ground coffee, evenly saturating the grounds.
Step 4
Stir with a spoon.Let steep for 18-24 hours at room temperature.
Step 5
After steeping, line the mesh strainer with cheesecloth and strain the cold brew into a new container to remove the coffee grounds.
Step 6
Mix the filtered cold brew concentrate with an equal amount of water to make a classic cold brew. The concentrate can also be mixed with milk. For example, 6 oz concentrate mixed with 6 oz. water makes 12 oz. of cold brew.
Step 7
Enjoy your fresh batch of smooth, bold cold brew!
