Method
1
Combine the coarse ground coffee and cold water in your large jar or pitcher.
2
Stir the mixture gently to ensure all grounds are fully saturated.
3
Cover the jar and place it in the refrigerator for 12 to 18 hours.
4
Strain the mixture through a fine mesh strainer lined with a coffee filter or cheesecloth into a clean container.
5
Discard the spent grounds and store the remaining liquid in the refrigerator.
6
Serve the concentrate over ice, diluting with water or milk if desired.
Barista note: Taste before adjusting — a small change in grind, dose, ratio, or time usually makes the biggest difference.
