How to Make Cold Brew

Cold brew coffee has become a beloved and trendy way to enjoy a smooth and refreshing cup of joe, especially during hot summer months. This cold-brewed delight offers a lower acidity level and a naturally sweet flavor profile, making it a hit among coffee enthusiasts. If you've always wondered how to make cold brew at home, you're in for a treat! In this ultimate guide, we'll walk you through the steps to create a delicious batch of cold brew coffee, ensuring you have a steady supply of this chilled perfection whenever you desire.

Why Make Cold Brew?

Cold brew is different from traditional iced coffee as it is brewed with cold or room temperature water over an extended period. The slow brewing process extracts the coffee's flavors without the bitterness associated with hot brewing methods. Cold brew is also highly versatile, as you can serve it over ice, mix it with milk, or experiment with various flavorings to suit your taste.

What You'll Need

  • Coffee Beans: Choose high-quality coffee beans with a flavor profile you enjoy. It's best to select beans with low acidity and a smooth, chocolatey, or nutty taste.
  • Cold or Room Temperature Water: Use filtered water for the best taste.
  • Large Container: You'll need a container large enough to hold your desired amount of cold brew coffee.
  • Coffee Grinder (Optional): If you have whole coffee beans, a grinder will allow you to grind them to your preferred coarseness.
  • Fine Mesh Strainer or Coffee Filter: You'll use this later to filter out the coffee grounds.
  • Cheesecloth (Optional): If you prefer an extra filtering step, have a cheesecloth on hand.

Step-by-Step Guide

Note: The method described below is a basic cold brew technique. Feel free to adjust the coffee-to-water ratio, brewing time, and filtration method to customize your cold brew to your liking.

Step 1: Coarsely Grind Coffee Beans (Optional)

If you have whole coffee beans, coarsely grind them to ensure the best cold brew extraction. The coarseness should be similar to that of sea salt.

Step 2: Mix Coffee and Water

In your large container, combine the coarsely ground coffee with cold or room temperature water. The standard coffee-to-water ratio for cold brew is about 1 cup of coffee to 4 cups of water, but you can adjust it based on your taste preferences.

Step 3: Stir and Soak

Gently stir the coffee and water mixture to ensure all the coffee grounds are saturated. Once mixed, cover the container and let the coffee steep for an extended period. The steeping time typically ranges from 12 to 24 hours, depending on your desired strength and flavor.

Step 4: Filter the Cold Brew

After the steeping time is complete, it's time to filter the cold brew. You can use a fine mesh strainer or a coffee filter to separate the coffee grounds from the liquid. If you prefer an even smoother cold brew, you can use a cheesecloth as an additional filtering step.

Step 5: Serve and Enjoy

Your homemade cold brew is now ready to be served! Pour it into a glass filled with ice and, if desired, add milk, cream, or any other flavorings to customize your cold brew experience.

Bonus Tips:

  • Cold Brew Concentrate: To create a cold brew concentrate, use a higher coffee-to-water ratio and dilute the concentrate with water, milk, or ice before serving.
  • Experiment with Flavors: Cold brew is incredibly versatile. Try adding syrups, spices, or extracts to create unique flavored cold brew beverages.


Making cold brew at home is a rewarding and straightforward process, offering a delightful coffee experience with its smooth and refreshing taste. With this ultimate guide, you have all the tools you need to create your cold brew masterpieces. Experiment with different coffee beans, brewing times, and flavorings to find your perfect cold brew combination. So, grab your favorite container, quality coffee beans, and get ready to enjoy a delicious batch of cold brew coffee anytime you desire.
