In your large jar or pitcher, combine the coarsely ground coffee with the cold water.

Using a spoon, gently stir the coffee and water mixture to ensure all grounds are saturated.

Cover the jar or pitcher with a lid or plastic wrap and let the mixture steep at room temperature or in the refrigerator for about 12 hours.

After steeping, place a fine mesh strainer over another jar or pitcher and pour the coffee mixture through the strainer to separate the grounds from the liquid.

Once strained, discard the used coffee grounds.

Pour the Cold Brew concentrate into a glass over ice. You can dilute it with water or milk to your desired strength.

Add any desired sweeteners or flavorings and stir well to combine.

Store any unused Cold Brew concentrate in an airtight container in the fridge for up to two weeks.
