Directions

1. Grind the coffee beans in a grinder. Don't make it too fine, it should look like coarse cornmeal.
   

2. Take a tall jar, add the ground coffee and pour the water over it. Stir well to mix.
   

3. Cover the jar and let it steep for at least 10 hours in the refrigerator.
   

4. Strain the mixture using a fine sieve or a cheesecloth. You can do this a couple of times to ensure your cold brew has no fine particles in it. This is your cold brew decoction.
   

5. You can add ice, chilled water, milk etc to it, based on what you'd like to have.
