1 1/3 cups of fine ground coffee 
4 cups of water

  • Combine coffee and water in a glass container or mason jar. Stir to combine well. Cover and let it 'brew' at room temperature for 8-24 hours (I usually make mine in the evening and let it brew about 12 hours overnight)

  • Use a grain strainer or put a coffee filter in a fine sieve over a mixing bowl and slowly pour coffee mixture through the filter. This is now your coffee concentrate.

  • To serve, mix about 1/3 coffee concentrate with 2/3 water. Increase the concentrate for a stronger cup of coffee. 
You can enjoy this hot or cold, depending on whether you add boiling water or cold water. Keep refrigerated. The concentrate will stay good for up to one week.
