Combine the water, coffee, sugar and cinnamon in your french press the night before you want to drink your iced coffee. Be sure to mix well so grounds are submerged in the water. Store in the refrigerator overnight with the lid of the french press on (but in the unpressed position).

The next morning, fill your favorite beverage tumbler with ice, press the cold-brewed coffee and pour it over the ice. Add the half and half, mix and enjoy!
