In a large jar or pitcher, add the coarsely ground coffee.

Pour the cold water over the coffee grounds, ensuring all are saturated.

Using a spoon, stir the mixture gently to combine.

Cover the jar or pitcher with a lid or plastic wrap.

Let it steep in the refrigerator for 12 to 24 hours, depending on your preferred strength.

After steeping, strain the coffee using a coffee filter or fine mesh strainer.

Fill a glass with ice and pour the cold brew over it.

If you prefer a sweeter beverage, add your favorite low-carb sweetener or flavored syrup to taste.

Stir well to combine.

Store any leftovers in the refrigerator for up to two weeks.
