To make cold brew concentrate, start by coarsely grinding your favorite coffee beans, using about 1.5 ounces per 8 ounces of cold water. Mix the grounds with water thoroughly in a large jar or French press, ensuring all grounds are saturated. Steep the mixture in the fridge for 12 to 24 hours, then strain out the grounds using a fine mesh or filter. Store the concentrate in an airtight container and dilute to taste before serving. If you keep exploring, you’ll discover tips to perfect your brew.
Key Takeaways
- Use coarsely ground coffee, about 1.5 oz per 8 oz of water, for optimal extraction and easy straining.
- Mix coffee grounds with cold water thoroughly, ensuring full saturation before steeping.
- Steep the mixture in the refrigerator for 12-24 hours to develop a rich, flavorful concentrate.

- Dilute the concentrate with water, milk, or milk alternative before serving, adjusting ratio to taste.

Making cold brew concentrate is simple and requires just a few basic steps. To start, you’ll need coarsely ground coffee—aim for a texture similar to sea salt. Using the right grind size is essential; too fine, and the mixture will be difficult to strain, too coarse, and the extraction may be weak.
Use coarsely ground coffee, similar to sea salt, for best cold brew extraction.
Mix about 1.5 ounces of coffee grounds per 8 ounces of water to create a strong concentrate. You can adjust this ratio based on how potent you want your brew, but this is a good starting point for a rich, flavorful result.
Next, combine the coffee grounds and water in a container, ensuring the grounds are fully saturated. You can brew in a French press or any large jar, but the key is to let the mixture steep in the refrigerator for 12 to 24 hours.
During this time, the cold water extracts the coffee’s flavors and caffeine slowly, resulting in a smooth, less acidic concentrate. After the steeping period, it’s time to strain the mixture. Place a filter-lined sieve or a fine mesh sieve over a clean bowl or pitcher.
Pour the coffee mixture through this setup, using a coffee filter or cheesecloth if needed, to catch any remaining grounds. Once strained, transfer the filtered cold brew concentrate into an airtight container. Store it in the fridge for up to one week.
Because the extraction process benefits from proper color accuracy, choosing high-quality coffee beans can enhance the flavor profile of your cold brew. When you’re ready to make cold brew coffee, simply dilute the concentrate with water, milk, or a milk alternative to taste. Typically, a ratio of one part concentrate to two or three parts water works well, but you can adjust based on your preference.
You can also brew your cold brew in a French press from the start if you prefer, adding water directly to the grounds and steeping as usual.
