Pour the coffee grounds into a large plastic container with a lid.
Fill the plastic container with water and stir the coffee grounds around with a spoon until all grounds are moistened.
Place lid on the plastic container and pop into the refrigerator overnight.
After the overnight process, place a layer of cheese cloth over a fine-mesh strainer. Place the strainer over another large plastic container with a lid.
Gently and SLOWLY pour the coffee over the strainer. If it becomes too full, stop and let it drain before continuing.
Keep pouring until all the coffee liquid has passed through the strainer and you're left with coffee grounds. You can also gently press the coffee grounds in the strainer with the back of a spoon to squeeze out more liquid.
Store in the fridge for up to three months (you'll likely finish it way before then!)

Notes
Keep in mind that this is a coffee concentrate so you'll need to dilute your coffee with some water when you make your coffee drink (unless you really like strong coffee). This is what I do:In a 16-ounce cold drink tumbler, fill with ice. Fill half the tumbler with your cold-brew coffee concentrate and just under a half of the rest of the tumbler with cold water. I add about 1/2 tablespoon of half-and-half and 1/2 tablespoon of sweetened condensed milk. Screw the lid on, pop in the straw, stir well and you've got yourself a refreshing coffee drink!!If you don't have a 16-ounce cold drink tumbler, you can just use a regular glass or mason jar or whatever you have. You don't have to make your coffee recipe exactly like how I make mine - everyone takes their coffee differently! This is just merely an idea of how I make mine :)
