How to Make Cold Brew Coffee in a Mason Jar Without Any Fancy Equipment

Are you tired of spending a fortune on cold brew coffee at your local café? Or maybe you've tried making it at home, but the equipment required seems too complicated and expensive. Fear not, because making cold brew coffee in a mason jar is not only easy, but it's also a cost-effective solution that will save you money in the long run.

What You'll Need:

- A mason jar (or any glass jar with a lid)

- Coarsely ground coffee

- Cold water

The Process:

Step 1: Measure out your coffee

For every 1 cup of water, you'll need 1/4 cup of coarsely ground coffee. Measure out the desired amount of coffee and place it in the mason jar.

Step 2: Add cold water

Pour cold water into the mason jar until it reaches the top. Make sure the coffee grounds are fully covered by the water.

Step 3: Stir the mixture

Use a spoon or a chopstick to stir the mixture until the coffee grounds are fully saturated with water. Make sure there are no clumps of coffee grounds left at the bottom of the jar.

Step 4: Let it steep

Place the lid on the mason jar and let it steep for 12-24 hours at room temperature. The longer you let it steep, the stronger the coffee will be.

Step 5: Strain the mixture

After the steeping process is complete, use a fine-mesh strainer or cheesecloth to strain the mixture into a separate container. This will remove any remaining coffee grounds and leave you with a smooth, concentrated cold brew coffee.

Tips and Tricks:

- Use high-quality, coarsely ground coffee for the best results.

- Experiment with different steeping times to find your preferred strength of coffee.

- Add milk, cream, or your favorite sweetener to customize your cold brew coffee.


Making cold brew coffee in a mason jar is a simple and cost-effective solution that doesn't require any fancy equipment. With just a few easy steps, you can enjoy a delicious, smooth cup of cold brew coffee in the comfort of your own home.
