What is ice drop coffee?

Ice drop coffee water-drip coffee, also known as Dutch coffee (Dutch coffee). It is said that during the Dutch rule over Indonesia, many varieties of coffee were grown by Robesta, and in order to drink these rather bitter beans in the tropics, they specially invented a device for brewing coffee with slowly dripping cold water.

An interesting phenomenon is that you can hardly find this kind of coffee in the Netherlands. Instead, it has sparked a wave of ice drops in Asia. In Japan, ice drop coffee has a history of hundreds of years, so ice drop coffee is also known as "Kyoto coffee" (Kyoto coffee) and "Japanese-style slow-drip" (Japanese slow drop). In South Korea, almost every cafe sells ice drop coffee, and many famous brands of ice drop appliances are from Japan and South Korea. In China, some boutique cafes are also starting to sell ice droplets. Next time you go to a cafe, remember to ask the barista.

The difference between chilled, cold bubble and ice droplets

Made by hot extraction

Iced coffee ice coffee refers to a cold drink coffee that is quickly extracted with hot water and then added with ice or cooled rapidly. It takes about 2 to 3 minutes to make.

Using cold extraction method to make

Cold brewed coffee Cold Brew refers to coffee extracted by soaking coffee powder in cold water of less than 5 ℃ for a long time, which takes about 8-12 hours. Also known as iced coffee.

Ice drop coffee water-drip coffee refers to coffee that uses a drop of cold water at a uniform rate to extract flavor substances from coffee powder, which takes about 4 to 8 hours, depending on the size of the equipment.

It should be noted here that iced coffee lowers the temperature of hot coffee and is far inferior to cold bubbles and ice droplets in taste.

Cold brewed coffee and ice drop coffee are both coffee extracted with cold water. Compared with coffee extracted with hot water, they can retain the flavor and aroma of coffee to the greatest extent, while softening the acidity and bitterness, because the coffee brewed in cold water is not easy to oxidize. It can also inhibit the appearance of sour taste. The acidic fat in coffee is not easily dissolved in cold water. )

Extraction of Ice drop Coffee

Basic principles of ①

The key to the production of ice drop coffee lies in "cold" and "slow". The ice water located in the container at the top of the equipment is controlled by the valve to infiltrate the coffee powder drop by drop. The coffee liquid is filtered and gradually collected in the pot at the bottom. The whole extraction process takes about half a day.

The secret of ② extraction

Ratio of water to powder: the ratio of coffee powder to ice is about 1: 10: 12, which can be determined according to personal preference.

Grinding: it is recommended to grind the coffee powder finer, which can increase the contact area between the coffee powder and water.

Choose beans: recommend deep-roasted coffee beans with a balanced taste.

Water speed: it is better to drip slowly with 2 drops in 3 seconds (40 drops per minute).

So the question is, what does the apparatus for making ice droplets look like?

In fact, as long as it contains the following four elements, it can be called curling.

① is a container that holds water and ice cubes and can adjust the speed of water droplets.

② is a container for coffee powder.

③ filter: paper, cloth or metal.

④ is a container for coffee liquid.
