Grind coffee beans and place in a quart glass jar.

Add water and put on a tight-fitting lid. Gently shake to incorporate coffee and water.

Place in refrigerator to brew over night. Shake a few times if you think of it.

In the morning, filter cold brew through a fine-meshed sieve into a fresh jar.

Your cold brew is ready to enjoy over ice, with plant-milk, maple syrup, or even a sprinkle of cinnamon.
