Cold Brew In a Mason Jar

Murat Aktas
To make cold brew coffee in a mason jar, combine coarsely ground coffee with water in a 1:8 ratio, steep for 12-24 hours, then strain. This method produces a smooth, concentrated coffee, perfect for diluting to taste and storing in the fridge​​.

Equipment

  • 1 Mason jar
  • 1 Filter

Ingredients
  

  • 100 gr Coffee Grounds
  • 800 ml Room Temperature Water

Instructions
 

  • Coffee-Water Ratio Calculation 
    The first thing you must do for homemade cold brew is adjust the coffee-water ratio correctly. The ideal coffee-water ratio is 1:8. So, you should use 8 parts of water for 1 part of coffee. For example, you can use 100 grams of coffee grounds for an 800 ml brew.
  • Grind Your Coffee Beans 
    If you are using pre-ground coffee, you can skip this step. I have something to tell you if you are grinding your coffee beans. Relatively coarser grinding is required for homemade cold brew in a mason jar.
    I prefer an extra coarse grind coffee as an ideal grinding degree in my recipes. 
  • Add Water and Stir
    Add the necessary amount of water according to the ratio you determined. Then, use a spoon to stir until all the coffee grounds are wet and soaked.
  • Steep 
    The ideal steeping time for cold brew is between 12-24 hours. This steeping time will determine the strength level of your coffee. The longer you steep, the stronger it will be. 
    You can steep your cold brew prepared in a mason jar for 12-24 hours in the refrigerator or countertop.
  • Strain Out The Coffee Grounds
    After waiting enough time for steeping, strain your coffee. The better filter you use, the fewer coffee grounds you will see in your cup.
    You can use Hario V60, Chemex, or Kalita Wave filters at this stage. Even cheesecloth can do the job.
  • Serve and Enjoy 
    After straining your cold brew coffee, dilute it according to your taste and serve it with ice. If the taste is too strong, you can add milk. 

Notes

If you have brewed more than you can consume at once, don’t worry about it. You can store cold brew coffee in the refrigerator for up to 2 weeks without spoiling.
