Cold brew concentrate is a new favorite of coffee drinkers looking for smooth, rich iced coffee without the bitterness or acidity found in hot-brewed methods. This creates a rich flavor without the sour compounds that can give hot coffee its edge when brewing by steeping coffee grounds in cold water for long periods. So, whether you are a busy professional in need of a quick AM kick or a home barista trying out new recipes, learning how to make cold brew concentrate is simple, cost-effective, and extremely rewarding.
Why choose cold brew concentrate?
Cold brew concentrate stands out for its versatility and superior taste. The slow extraction process (typically 12–24 hours) results in a low-acid, silky-smooth beverage with chocolatey, nutty, or fruity notes depending on your beans. It's highly concentrated, so a small batch goes a long way—dilute it with water, milk, or your favorite plant-based alternative for endless customizations like lattes, cocktails, or even desserts.
Plus, it is cheaper than what you spend at the café, and you are totally in charge of how strong you prefer it and what quality coffee beans you get! And with premium beans (and their green coffee for a unique twist) and Greenbrrew touting top-notch sources, the finished product is elevated.
What You'll Need:
Gathering the right tools and ingredients ensures a clean, professional result:
- Coffee: 1 cup (about 100–120 g) coarsely ground coffee beans. Opt for medium to dark roasts for richness. Freshly ground is best—Greenbrew's quality selections work wonderfully here.

- Equipment:
-
-
Large glass jar or pitcher (e.g., 1–2 quart mason jar).

Step-by-Step Guide to Make Cold Brew Concentrate
Follow these easy steps for consistent results every time.
1. Grind and Prepare the Coffee
Grind your beans to a coarse texture similar to that of sea salt or French press grounds. This will help avoid bitterness and excess extraction while making for easy straining. Put the filth into your jar.
2. Add Water and Stir
Add the cold filtered water slowly, stirring gently to ensure saturation of all grounds. The bloom facilitates gas release so that extractions are more uniform. Cover the jar and shake it well.
3. Steep
Allow mixture to sit at room temperature for 12–18 hours or in the refrigerator up to 24 hours. Stronger concentrate comes from longer steeps. Avoid direct sunlight.
4. Strain the Concentrate
Place a sieve lined with cheesecloth or filter over another clean container and pour the mixture through. If required, press on the grounds softly—avoid squeezing so hard that it becomes fluffy or cloudy sediment. For crystal clarity, strain again. Throw away the spent grounds (compost them!)
Now your cold brew concentrate is ready! Will last up to 14 days in an airtight container in the fridge.
Serving Suggestions and Tips
To Serve, Mix a 1:1 ratio (more or less depending on how strong you like your iced coffee) with water/milk of choice to make the concentrate. Make it different by adding ice, sweeteners, vanilla syrup, or cream. Try it over ice with a dash of citrus for summer.
Pro Tips:
- Experiment with ratios: A stronger 1:4 brew from Greenbrrew beans creates a versatile base for espresso-style drinks.
- Use fresh, high-quality beans for the best flavor—avoid pre-ground if possible.
- Scale up batches for weekly convenience.
- Latest trends (as of 2026) include flavor infusions like vanilla beans or spices during steeping for gourmet results.
Common Mistakes to Avoid
- Using too fine a grind, which can lead to bitterness or clogging.
- Insufficient steeping time, resulting in weak flavor.
- Skipping filtration, leaving gritty sediment.
