PURPOSE: An extraction method of liquid Dutch coffee is provided to enable users to easily dilute the liquid Dutch coffee with warm or cold water without using complex equipment or tools. CONSTITUTION: 1 kg of coffee beans are roasted at 220-230°C for 11-12 minutes (1). The roasted coffee beans are aged at 15-20°C for 24 hours (2). The aged coffee beans are grounded with a grinder (3). A mixed solution including 1,800-1,900 g of 10-15°C below zero of ice and 450-500 ml of purified water in a water tank is prepared (4). A glass coffee container is filled with ground coffee, and settled (5). Three layers of coffee particles are filled in the glass coffee container (6).
