I once read a report: Mr. Timko, the boss of an American boutique coffee company, felt very distinctive after seeing ice drop coffee in Japan, and fell in love with it after tasting it, so he studied and promoted it.

Ice drop coffee, also known as water drop coffee, ice brewed coffee, is a way to make coffee drinks. Ice drop coffee uses ice water, cold water or ice cubes to extract coffee, which is very slow and often takes hours, so ice drop coffee is more expensive.

History: the apparatus for making iced coffee was invented in the Netherlands, also known as the Dutch iced coffee drip filter. After being carried forward by the Japanese, the current production of ice drop coffee maker is mostly Japanese manufacturers. Ice drop coffee has also become popular in the United States in recent years.

Production: the upper layer of the Dutch iced coffee drip filter is a container of water, ranging from 500cc to 3000cc according to capacity. At the bottom of the container is a switch that controls the flow of water, a long tube containing coffee powder in the middle, and a glass pot that holds coffee. When in use, put cold boiled water or ice into the upper container and coffee powder into the middle tube. The coffee powder is about between the thickness of the powder used in the French filter press and the siphon coffee maker. Turn on the switch of the upper container and let the water drop one drop at a time. The water will slowly seep through the coffee powder and drop into the lower glass pot. Basically, it's about an hour of 100cc. Adjust it to 3-5 seconds a drop as needed.

Drink: drink well in the refrigerator after drinking, the taste will be more rich and delicious.

Principle: ice drop coffee is mainly extracted by condensation natural osmotic water pressure and bit by bit. The taste of the extracted coffee will change according to the coffee roasting degree, water quantity, water temperature, water drop speed, coffee grinding thickness and other factors, and the extracted coffee has different flavor.

Features: coffee powder is 100% soaked in low temperature and moist, and the extracted coffee has a strong, smooth and rich taste. Adjust the speed of water droplets, slowly dripping with cold water, with a low temperature of 5 degrees Celsius, dripping for a long time, rich coffee flavor and low caffeine content.
