Cold brew concentrate is a versatile base for creating coffee drinks, offering a smoother, less acidic experience than traditional hot methods. With the right proportion of coffee to water and proper steeping time, you can create a concentrate that works for multiple recipes.

What is Cold Brew Concentrate?

Cold brew concentrate isn't the same as regular cold brew coffee. It's a stronger, undiluted version meant to be mixed with water, milk, or other liquids before drinking. The typical recipe uses a coffee-to-water ratio of 1:4, making it four times stronger than standard brewed coffee. This concentrate can be stored in the fridge for up to two weeks, reducing the hassle of daily brewing.

For example, using 250 grams of coarsely ground coffee with 1 liter of cold water is a common starting point. The result is a rich, flavorful coffee concentrate that can be used to create everything from iced lattes to coffee cocktails.

Step-by-Step Guide to Making Cold Brew Concentrate

Making cold brew concentrate is straightforward if you follow these steps:

  1. Choose your coffee: Go for medium to dark roast beans for a richer flavor. Brands like Stumptown, Blue Bottle, or Lavazza tend to perform well.
  2. Grind your beans: Use a burr grinder for consistency. Aim for a coarse grind similar to sea salt. If you're unsure, read how to clean your burr grinder for maintenance tips.
  3. Measure coffee and water: Stick to the 1:4 ratio. For 250 grams of coffee, you'll need 1 liter of filtered water.
  4. Combine and stir: Mix the ground coffee with water in a large jar or French press. Stir to ensure all grounds are saturated.
  5. Steep for 12-24 hours: Cover the container and let it sit at room temperature or in the fridge.
  6. Strain the concentrate: Use a fine mesh sieve or coffee filter to remove the grounds. A French press works well for this step.

After straining, transfer your concentrate to a sealed container and refrigerate. It will stay fresh for up to two weeks.

How to Use Cold Brew Concentrate

Your cold brew concentrate is incredibly versatile. Here are five ways to enjoy it:

  1. Iced coffee: Mix one part concentrate with one part cold water. Add ice and enjoy. For a stronger brew, adjust the ratio to 2:1.
  2. Hot coffee: Heat water and combine with the concentrate in a 2:1 ratio. This method maintains the smooth flavor of cold brew while providing warmth.
  3. Coffee milk: Mix equal parts concentrate and milk (dairy or plant-based) for a creamy, chilled drink. Brands like Oatly or Califia Farms make great options for non-dairy alternatives.
  4. Dessert topping: Drizzle cold brew concentrate over ice cream for a coffee-flavored dessert.
  5. Cocktails: Use the concentrate in espresso martinis or a twist on an Old Fashioned by mixing it with bourbon and simple syrup.

Experiment with different ratios to find your ideal flavor profile.

Tips for Storing and Optimizing Your Cold Brew Concentrate

Proper storage ensures your cold brew stays fresh and flavorful. Keep it in a glass container with a tight lid in the fridge. Mason jars work well and are widely available for under $10. For best results, use your concentrate within 10-14 days.

If you're making large batches, consider freezing portions in ice cube trays. These cubes can be added directly to milk or water for a quick drink without dilution.

Surprisingly, many people overlook the water quality when making cold brew. Using filtered or bottled water, such as Evian or Brita-filtered, can significantly enhance the flavor. Also, don't skip cleaning your equipment. Coffee oils can build up, affecting the taste. Refer to how to clean your burr grinder for detailed guidance.

FAQ

How long should cold brew concentrate steep?

Steep it for 12-24 hours. Shorter times (12 hours) produce lighter flavors, while a full 24 hours creates a richer, deeper concentrate.

Can you freeze cold brew concentrate?

Yes, it freezes well. Use ice cube trays for portioning. Frozen cubes can be added to milk or water without losing flavor.

How do I dilute cold brew concentrate?

Typically, use a 1:1 ratio of concentrate to liquid (water or milk). Adjust to taste if you prefer stronger or lighter coffee.

What grind size is best for cold brew?

A coarse grind is essential. It prevents over-extraction and makes straining easier. Aim for a texture similar to sea salt.

Is cold brew concentrate stronger than espresso?

Yes, it is. Cold brew concentrate has a higher caffeine content per ounce, but it’s less acidic than espresso.
