  • Ground coffee
  • Filtered water

Essential Tools

  • Mason Jar
  • ~50cm square natural cheesecloth fabric


  • Fill a third of a mason / large glass jar with ground coffee (you can grind yourself or purchase already ground).
  • Fill half of the jar with filtered water. Pour over the water in a circular motion to wet all of the grounds.
  • Allow the grounds to start to soak into the water for a few minutes.
  • Fill up the rest of the jar with water.
  • Close the jar lid and leave in a cool spot out of the sun for 24 hours to brew.
  • The next day: fold the cheesecloth fabric so there are ~4 layers. Lay this over the opening of another large jar or plastic container and push in the middle slightly to create a well shape.
  • Carefully pour the cold brew coffee into the cheese-cloth well to filter the coffee from the grounds. You may need to pour it in a bit at a time to allow the coffee to filter through the fabric. Twist and squeeze the cheesecloth to remove all of the liquid.
  • Once filtered, remove the cheesecloth, discard the coffee grounds**, and wash the cheesecloth clean with plain water. Wash the original mason jar out with hot water so that it is clean of any leftover coffee grounds.
  • Lay the cheesecloth over the opening on the original mason jar and filter the coffee back into the jar. You are essentially filtering your coffee twice to make sure there any no grounds left in the liquid.
  • Store your cold brew concentrate in the fridge.
  • To serve, add ice to a large glass, pour in as much cold brew concentrate as you like and top with filtered water. Add in milk / cream as you like.


** Don’t just throw away the leftover coffee grounds – these are excellent for your garden or to make a sugar coffee body scrub!
