Mix the coffee grounds (1 cup) with the water (4 cups) in a container or pitcher and refrigerate for at least 12 hours, and as long as 48 hours.
Strain the coffee with a fine mesh sieve lined with cheesecloth or coffee filter.
In a small bowl of pyrex measuring cup, mix the honey (1/4 cup) with the warm water (1/4 cup) to make a quick simple syrup. Stir until honey is dissolved.
Pour 1 cup of the cold brew coffee over ice in a glass, then add 2 tablespoons of the honey simple syrup and 1/2 cup of the milk.
Stir and enjoy!
Notes
This cold brew coffee is especially strong, since a lot of milk is added to it so it doesn't taste watered down. You can use the cold brew coffee as a concentrate, and if you prefer black iced coffee, just water it down a bit. Or, you can brew it with half the amount of coffee grounds.
For a party or to serve at brunch, I recommend brewing and straining the coffee and mixing the honey simple syrup beforehand. You can serve each separately and let guests pour themselves however much coffee they want.
