Grind your coffee beans: Use a coarse grind, similar to sea salt. A burr grinder is ideal for a consistent grind, which is crucial for optimal extraction.

Combine coffee and water: In a large pitcher or jar, combine the coarsely ground coffee and filtered cold water. Stir gently to ensure all grounds are saturated.

Steep the coffee: Cover the pitcher or jar and let it steep at room temperature for 12 to 24 hours. The longer it steeps, the stronger the flavor. For a balanced taste, 18 hours is a great starting point.

Strain the coffee: Once steeped, carefully strain the coffee concentrate. You can use a fine-mesh sieve lined with cheesecloth, a nut milk bag, or a dedicated cold brew maker. Strain it twice for an extra-smooth result.

Dilute and serve: Your cold brew concentrate is ready! To serve, dilute it with water or milk to your preferred strength (a common ratio is 1:1 concentrate to liquid, but adjust to taste). Pour over ice and add any sweeteners or creamers you desire.
