Q. Extraction rate has dropped dramatically?

A. If the filter is dry or cold, the extraction speed will drop drastically.

Be sure to thoroughly drain the filter with boiling water before adding beans and extracting.

If you are concerned about clogging, you can also use a paper filter.


Q How and how often should I clean the filter?

A Please rinse the beans and surface dirt with hot water immediately after each use.

Please run the water through until the water runs clear.

If you use detergent, run the water longer and make sure no detergent remains in the filter.


Q How do I clear clogging?

A Boil the water once every 10 times.

Boil water in a pot for at least 5 minutes.

We recommend adding 2 teaspoons of baking soda to the water to increase the cleaning effect.

After boiling, do not touch the filter until it cools down.

The filter may break if it is cooled too quickly.

After that, run the filter under hot water to remove the baking soda.

In case of severe clogging, place the filter on a net and bake it on the stove for 10 minutes. Be careful not to burn yourself. After baking, do not touch the filter until it cools down.

After that, run the filter through hot water again.


Q. What is the best way to drip by hand?

A It is the same as general hand drip. At first, pour in just enough water to soak the beans in the hot water and let it steep for about 30 seconds. After that, pour hot water several times. The larger the volume of hot water, the faster the extraction speed.


Q. What is the appropriate bean size?

A Coarse is recommended. Set the grinder to the coarsest memory setting.

Q. What type of beans is suitable?

A We recommend deep-roasted beans, but you can use your favorite beans.


Q How does the taste change?

A Many people use the words "mellow," "clear," "smooth," and "sweet.

It removes miscellaneous and bitter tastes. (Taste varies from person to person.)


Q What is the structure of the filter?

A. The filter is made up of numerous invisible micron-sized holes (1 micron is 1/1000 of a millimeter). The thickness of the filter is used to filter the coffee three-dimensionally.


Q Can it be used for other than coffee?

A. Yes, it can be used to filter water, tea, shochu, wine, etc. You can enjoy a mellow taste. Be sure to pre-fire the filter before filtering another beverage.

You will not be able to enjoy the original taste due to the components of another beverage adhering to the inside of the filter.
