Water drop coffee, also known as Dutch coffee, is made with cold or ice water.

Drip coffee, also known as Dutch coffee, the kettle was first invented by Archbishop D'Bello of Paris in the early 19th century.

This brewing method is done with cold water or ice water, so that cold water or ice water is like water droplets, slowly extracting coffee essence at a rate of about 40 drops per minute, because the speed is very slow, so we should choose finer ground coffee powder to extract. This kind of coffee brewed for a long time contains very low caffeine, so it tastes very refreshing. In ordinary cafes, dripping coffee costs three times as much as regular coffee, and you have to make an appointment in advance.

Drip water control can be divided into two types:

First, soft water-lower the coffee pot, near the coffee bag is the way to make soft water, the amount of water control should be small, this method is suitable for making coffee with less weight.

Second, hard water-raise the coffee to make the water droplets tick, and the amount of water should be controlled bigger. this is the method of operating hard water, which is suitable for making mellow and delicious coffee with hard water for a long time.
