Combine the coffee grounds and water in a large container. Stir to wet all the grounds, then cover and steep at room temperature overnight (for at least 8-12 hours).

Line a fine mesh strainer with a clean t-shirt and place it on top of the container you’re using to store the coffee. Pour the coffee through, and discard the grounds (we put ours in the garden).

Measure your coffee concentrate (I had 7 cups) and dilute as desired with additional water. I added 9 cups of water to achieve the flavor I was hoping for, but you can dilute it more or less based on your taste.

Store in the refrigerator and serve over ice. It’s great on its own or with simple syrup, sweetened condensed milk or just a splash of your favorite type of milk.
