Making your own cold brew concentrate at home allows you to save money and have full control over the strength and flavor.
Cold brew concentrate, in contrast to regular hot coffee, is made by gently steeping cold water, resulting in an aroma and flavor that are more subtle and less acidic and harsh than regular coffee. If you perfect how to make cold brew concentrate, you’ll have a refreshing coffee alternative on hand whenever you need one.
1. What Is Cold Brew Concentrate?
Cold brew concentrate is a highly concentrated coffee made by steeping coarse coffee grounds in cold water for an extended period. It is stronger than regular cold brew and is typically diluted with water, milk, or ice before drinking.
Cold brew vs. Cold brew concentrate: The main difference is strength.
- Regular cold brew is ready to drink.
- Cold brew concentrate is brewed using more coffee and less water.
- Concentrate is usually diluted before serving.
- Concentrate takes up less storage space and allows you to adjust the strength of each cup.
2. How to Make Cold Brew Concentrate
Ingredients and Equipment Needed
Ingredients:
- 1 cup coarsely ground coffee
- 4-5 cups cold filtered water
Equipment:
- Large mason jar, pitcher, or French press
- Spoon for stirring
- Fine mesh strainer
- Cheesecloth, coffee filter, or nut milk bag
- Airtight storage container
Using coarse coffee grounds is important because fine grounds can produce a bitter, muddy brew.
5-Step Guide to Make Cold Brew Concentrate
Step 1: Measure Your Coffee and Water
For beginners, start with a 1:5 coffee-to-water ratio. For example:
- 1 cup coffee grounds
- 5 cups cold water
This ratio creates a strong concentrate that can later be diluted.
Step 2: Combine Coffee and Water
Add the coffee grounds to your container and pour the cold water over them.
Stir thoroughly to ensure all grounds are fully saturated. This helps achieve even extraction throughout the brewing process.
Step 3: Let It Steep
Cover the container and let it steep.
Recommended steeping times:
- Room temperature: 12-18 hours
- Refrigerator: 16-24 hours
Most coffee experts consider 16-18 hours the sweet spot for a balanced and smooth concentrate.
Step 4: Filter the Coffee
Pour the mixture through a fine mesh strainer lined with cheesecloth or a coffee filter.
For extra clarity, strain a second time. This removes sediment and creates a cleaner final concentrate.
Step 5: Store and Serve
Transfer the finished concentrate into an airtight bottle or jar. To serve:
- Mix 1 part concentrate with 1 part water.
- Mix 1 part concentrate with 1 part milk.
- Pour over ice for a refreshing drink.
Adjust the dilution ratio according to your preference.
Different Brewing Methods for Cold Brew Concentrate
These methods can produce excellent results when the coffee ratio and steeping time are correct. Just make sure to choose the most suitable one based on your budget, available equipment, and desired batch size.
- Mason Jar Method: The most affordable option. Simply steep and strain. Requires minimal equipment, as any glass jar and fine mesh strainer work. Best for beginners or small batches.
- French Press Method: Easy cleanup because the built-in filter quickly separates the grounds. Produces cleaner results with less sediment. Works well if you already own a French press.
- Dedicated Cold Brew Maker: Many cold brew systems include reusable filters and simplify the entire brewing process. Designs range from simple to advanced, with some featuring convenient spouts and measurement guides built in.

3. Untold Tips to Master Your Cold Brew Concentrate
Best Coffee-to-Water Ratio
The ideal ratio depends on your preferred strength.
- 1:4 ratio = very strong concentrate
- 1:5 ratio = standard concentrate
- 1:6 ratio = slightly lighter concentrate
For most people who are learning how to make a cold brew concentrate, a 1:5 ratio provides the best balance between flavor and strength.
How Long to Steep Cold Brew Coffee Concentrate
Steeping time dramatically affects flavor.
- Under 12 hours: weak and under-extracted
- 16-18 hours: balanced and smooth
- Over 24 hours: risk of bitterness
Temperature also matters. Refrigerator brewing generally requires a longer steep than room-temperature brewing.
Proper Storage Tips
Store cold brew concentrate in a sealed container inside the refrigerator.
For best flavor:
- Consume within 7 days
- Safe storage up to 2 weeks in most cases
- Keep away from strong-smelling foods
Proper storage helps maintain freshness and prevent flavor degradation.

Common Mistakes to Avoid
Using Fine Coffee Grounds
Fine grounds can lead to over-extraction and bitterness. Always choose a coarse grind.
Steeping Too Long
Many beginners assume longer is better, but over-steeping can create harsh flavors.
Incorrect Coffee-to-Water Ratio
Using too little coffee creates a weak concentrate, while using too much can produce an overly intense brew.
Forgetting to Dilute
Cold brew concentrate is designed to be diluted before drinking. Consuming it straight may result in an overly strong flavor and caffeine content.
