Add the coffee and 1 cup of water to a large (8 cup) capacity coffee plunger/French press. Stir so that the coffee grounds are all wet. Add the remaining water, stir again and leave sitting on the bench for 12 hours.
Carefully plunge/press the coffee and pour into a glass or plastic bottle and store in the fridge.
Serve over ice with your choice of milk.
Store in the fridge for 3 or 4 days.
* If you are grinding your own whole beans, leave them pretty coarse but you can also use plunger/espresso ground beans and they work just as well!
