0 1 preheat coffee cup

It is recommended to preheat the cup with hot water before flushing the ear. This can create a similar "constant temperature" environment, slow down the speed of coffee temperature drop during brewing, and retain the best flavor.

Suitable water temperature

Do not brew directly with boiling water. Generally, the water temperature of brewing ears is suggested to be between 85-92 degrees Celsius. The deeper the roasting degree of coffee, the lower the recommended water temperature for brewing.

03 Appropriate water injection quantity

Usually, the ratio of powder to water for brewing ears is 1: 16- 1:20. Take the origami ear as an example, the appropriate water injection amount is about 180g g ... If the brewed coffee is too weak, the water injection amount can be reduced.

04 two-step water injection method

The first water injection, half water injection, small water flow around the water injection, so that the extraction is uniform and sufficient.

For the second water injection, water is injected in the center after the liquid level rises to reduce turbulence and avoid over-pumping.
