Cold brew isn't just iced coffee. Because the coffee grounds are never exposed to heat, the resulting brew is up to 60% less acidic and naturally sweeter than hot-brewed coffee.

Ingredients You Need

• 1 cup coarsely ground coffee beans (the coarseness is crucial)
• 4 cups filtered water

Step-by-Step Instructions

1. In a large mason jar or pitcher, combine the coarse coffee grounds and filtered water. Stir gently to ensure all grounds are wet.

2. Cover and let it steep at room temperature for 12 to 24 hours. (18 hours is the sweet spot for a strong but smooth concentrate).

3. Strain the mixture through a fine-mesh sieve lined with a coffee filter or cheesecloth into a clean jar.

4. You now have Cold Brew Concentrate! Do not drink this straight—it is very strong. To serve, mix 1 part concentrate with 1 part water or milk over ice.

Storage Instructions

Store the filtered concentrate in an airtight jar in the refrigerator. It will stay fresh and delicious for up to 2 weeks.

Troubleshooting: Why is my Cold Brew Coffee Concentrate not turning out right?

If you are having trouble getting this recipe right, ensure you are measuring ingredients accurately. Baking and cooking are sciences, and the right ratios matter. Also, check your oven temperature; many ovens run hot or cold.
