Cold Brew Coffee Ratio

Determining how you will use your coffee will help you decide on the best cold brew coffee ratio. Cold brew is great poured over ice, as a part of a latte, or reheated and enjoyed hot.

Cold Brew to Enjoy as Hot Coffee*

  • 1 cup brewed cold brew coffee
  • 1/4-1/2 cup hot water


  • In a blender or a coffee grinder, coarsely grind beans. Check the photo above to see the texture. It's important to very coarsely grind beans so that the grounds are easy to filter out and your coffee doesn't turn silty. Make sure all beans are broken up, but are in much bigger pieces than you'd typically use.
  • Add coffee grounds to a French press, or alternately, a mason jar. Pour water on top of coffee grounds, and then use a long handled spoon to mix the grounds into the water. The grounds will float, but make sure they are all wet.
  • Allow the coffee to cold brew in the refrigerator or in a cool space in your house over night or up to 24 hours.
  • If using a French press, just press down the handle to strain the coffee grounds, and then the coffee is ready to use. If using a mason jar, I have found using a nut milk bag is the easiest way to quickly drain the coffee and separate the grounds. Cheese cloth also works.
  • Enjoy the coffee poured over ice, mixed with milk for a latte, or reheated as a hot beverage.



*Add hot water to cold brew coffee to enjoy as a hot beverage. I like mine less strong, so I like a ratio of 2:1, but if you prefer strong coffee, try a 4:1 ratio of cold brew to hot water.
