1. Soak at low temperature. According to this method, sweet and delicious iced coffee can be made, which is 67% less acid than hot brewed coffee. Low-temperature brewing can also remove the unpleasant bitterness in hot brewed coffee.

2. Mix water and coffee. According to your own taste, add a certain amount of coarse ground coffee to the pot. The deeper the roasted fragrant coffee beans are, the stronger the coffee aroma will be.

Add water. Add 9 cups of cold water or normal temperature water to the water tank.

Soak. Put a lid on the pitcher. Soak in the shade for at least 12 hours.

5. After soaking, water should be separated from coffee powder.

Filter the coffee. Gently pour out the coffee, pass through a small sieve and pour it into another container.

7. Put a strainer on the sieve (two paper towels are enough), and then gently pour in the mixture of coffee powder and water to completely separate the water from the coffee powder.

8 Sweet and rich coffee concentrate is ready.

9. It's time to enjoy! Add a certain amount of ice to the glass, pour in one part of coffee concentrate, and then add three parts of cold water or milk. You can add sugar according to your own needs.
