Description

The present invention relates to an iced coffee brewing device.

Conventionally, the main method for extracting coffee beverages is to first grind coffee into powder and then pour boiling water into the coffee powder to extract flavored coffee. Hot water can quickly extract the flavor of coffee, but high temperature makes it easy to extract the bitterness component in coffee, and the flavor of coffee becomes biased toward bitterness. If you want to drink iced coffee, you have to add ice, which has the disadvantage that the flavor of the coffee liquor is diluted and affects the taste.

There is a method to give the coffee liquid a different taste from the high temperature extraction method by low temperature extraction, and the low temperature extraction method mainly puts coffee powder in a paper filter or a filter and then injects cold water to extract the coffee powder. It is soaked in cold water and slowly extracted the flavor of coffee in the cold water, and after about 10 to 24 hours, a coffee with a flavor is formed at a low temperature.
As a coffee brewing device, for example, the one described in Patent Document 1 is known.
