The key is to extract at room temperature. Extracting at room temperature for a long time fully brings out aromas and flavors that cannot be extracted at low temperatures.

Adjust the grind size based on the roast level, with medium grind as a base. If you feel a powdery or gritty texture, filter the coffee with a dripper (paper filter) when transferring it to another container after extraction to achieve a clear coffee.

For light roasts, we recommend adding a small amount (1-2g per 200ml) of unrefined cane sugar to further enhance the flavor, mellow the acidity, and add body. The timing for this is to add it to the pot before pouring water, then stir after adding water. Since room temperature water is used, it will dissolve thoroughly.

After extraction, store in the refrigerator and consume within 2-3 days.
