Mason Jar Cold Brew Coffee Recipe

Table of Contents

Cold brew coffee is one of the tastiest caffeine boosts on earth. It is a strong cup of joe with a mild, smooth flavor served over ice. Cold-brew lovers know that if you want to start your day with this drink, you’ll have to wait in the drive-thru on your way to work.

Instead of going to a coffeehouse every single day, make your own cold brew at home and have your drink at the ready! Brewing cold brew inside of a mason jar is a simple and effective way of making the best iced coffee you’ve ever tasted. Plus, it takes very few ingredients to make.

This recipe is the perfect one to dip your toes in making your coffee at home. It yields about 3 cups of coffee in total. If you decide that cold brew is too strong or you do not like the flavor, not many materials are wasted. You can go back to buying your cold brew from the store, although that is highly unlikely.


To make this easy coffee recipe, you will first need to grind your coffee beans. Grinding your coffee from whole beans is the best way to ensure a perfect final product. If you use pre-ground or finely ground coffee, the cold brew will become cloudy as it brews.

Simply add the beans to the grinder and pulse in short bursts until the grounds are all broken but not fine. Add them to a large mason jar and fill with water until it reaches the top of the jar. Secure with the lid and place in the fridge. Allow the coffee to brew for 12-24 hours.

To make sure no grounds end up in your final cold brew, strain the coffee through a strainer and a coffee filter. Pour into a clean mason jar with a lid and store in the fridge for whenever you want a perfect cold brew or cold brew latte.

This cold brew is technically coffee concentrate, so it is pretty strong. Generally, you should add ½ cup cold brew and ½ cup water or milk to dilute the coffee just enough. To control the strength, taste the coffee after 12 hours as it sits. You can strain the coffee ground once the robustness is to your liking.

Mason jar cold brew is just the first step in making a rich and bold iced coffee. What you add to it is what makes cold brew unique. By keeping your favorite cream or plant-based creamer in the fridge, you can have the perfect iced coffee in seconds. Perhaps you’d like to experiment in making your own homemade simple syrup in different flavor varieties. The possibilities are endless.

Make this cold brew on a Sunday, allow it to brew, and by Monday you have the perfect, smooth, slightly sweet drink to invigorate you. Homemade cold brew is the best way to start your day!

Making Needs


  • 4 cup mason jar with lid
  • Strainer
  • Coffee filter

Coarsely grind your whole coffee beans in a coffee grinder. Pulse 5-6 times until all beans are broken but not fine. You want a chunky grind on the beans.


Add the beans to your mason jar. Fill to the top with water and place the lid on top.


Place the mason jar into the fridge for 12 hours. Taste your cold brew to see if you want it stronger. If so, keep tasting occasionally until 24 hours have passed or until the coffee is to your desired strength.


Situate your coffee filter inside your strainer and set that over a large bowl. Strain the coffee through the filter. Pour the cold brew into a clean mason jar and secure the lid. Store in the fridge and serve over ice with equal amounts of water or milk.
