Complete solution of ice drop coffee technology | the Dutch coffee of the table in summer

The shape is strange, the upper pot is filled with ice water, drop by drop, drop by drop into the middle pot of coffee powder, slowly infiltrate and extract the coffee liquid and then drop it into the next pot, which is quite a bit of a rigorous style of a scientist.

It is the ice drop coffee (Dutch coffee) that bursts the table in summer.

This ice drop coffee, which is said to have been invented by the Dutch and called Dutch coffee, has become very popular in Asia in recent years.

Almost every cafe in South Korea sells ice drop coffee, which has given rise to a lot of cool ice drop equipment, canned ice drop coffee, portable ice drop coffee in small packages, and even super-concentrated ice drops that can be diluted to five or six times.

Today, we will uncover the secrets of ice droplets and teach you how to make booming ice drops of coffee at home!

HOW TO MAKE DUTCH COFFEE

Ice drop apparatus, usually requires three parts.

Part 1 | Container that can hold water / ice cubes and adjust the flow rate

Part 2 | Coffee powder container

Part 3 | the container that holds the dripping coffee liquid

Made by Dutch Lab, it has a very cool "Gothicism" ice drop coffee maker with a Gothic architectural appearance; a "liquid separation funnel" simple device assembled by chemical enthusiasts themselves; and even more creative people even use water bottles to play with ice drops at home!

In short, as long as you prepare these three parts, assembled together to form an instrument, can be called ice droplets.

The price, Tut-tut, the human flesh back also costs more than 50,000, and imports are more expensive.

Water dispensers can cook hot pot, and water bottles can also be used as ice droplets.

Make ice droplets

In the final analysis, ice droplets also use cold water or ice water to slowly infiltrate coffee powder, exchange time for space, and dissolve the beautiful flavor substances in coffee. But compared with cold soaking (it takes about 8-12 hours for cold water to soak with coffee powder), it only takes about 5 hours to make ice droplets.

So, how should it be made?

As the saying goes, "if you want to do good work, you must first sharpen its tools." if you have the same poor hands-on ability as I do, and you are reluctant to spend a lot of money on equipment, I recommend two easy-to-use and affordable ice drop kettles for you: My Dutch and Bruer.

Simple and convenient, after adjustment, as long as you sit comfortably and wait, there will be a delicious ice drop of coffee which is very suitable for home use and does not need to be filtered. When friends get together in summer, they can be poured out and shared with everyone!

To cause to move suddenly.

STEP 1. Weigh coffee beans (80g) and grind them

The scale is Huijia bean grinder "4.5".

There are differences in grinding thickness between different brands of bean grinders.

STEP 2. Install components. Then pour the coffee powder into the container in the middle section, flatten it, and put a round filter paper on it. The purpose of the filter paper is to make use of capillarity to let water evenly penetrate coffee powder and prevent coffee powder from being extracted in areas where only water is dripping.

STEP 3. Weigh 400g ice water (if you use ice cubes, about half of it, that is, 200g ice cubes + 200g normal temperature water), use filtered water for both ice cubes and water.

STEP 4. Adjust the flow rate to about two drops in three seconds.

STEP 5. Wait for about five hours, and then you can drink!

Ps: add ice or milk to the right concentration to drink according to your preference.

After the coffee is extracted, it can be frozen in the refrigerator for 3 to 5 days. But Mr. Cha still suggests drinking it as soon as possible, for fear that the coffee liquid will absorb all kinds of flavors in the refrigerator, and on the other hand, the coffee will slowly oxidize and ferment, losing its "native flavor" and replacing it with a wine-like fermented flavor.

There is no difference between good and bad, but Mr. Cha still prefers the original flavor of coffee, so after it is made, I hope you can drink it as soon as possible!

Ice droplets don't oxidize? Who said that? call that man out!

Quan A time

1. What are the characteristics of cold bubble?

Cold brewed coffee will be softer in acidity and bitterness. The aroma will be very different from that of hot coffee, with less fruit and flowers and prominent caramel and nut flavors. But it should be noted that the caffeine in cold bubbles is very high! So drinking a lot is not recommended. .

two。 Ice drops are so simple. Why are they so expensive?

A: I think it's strange, too. ..

3. What are the benefits of ice droplets?

Can brew more coffee at one time, save trouble, and the probability of failure is low! High concentration of coffee, very suitable for friends who like to add milk, can also be used to make a variety of creative drinks ~

4. Can you change the coffee into tea and change it into iced tea?

Very well, my friend, you have entered the field of great wisdom!

5. The relationship between the velocity of ice droplets and time?

20 drops of water is about 1ml, so 1 drop per second can drop 180ml in an hour. However, because the ice drop appliance we recommend will be lower and slower, the initial drip speed can be controlled at about two drops in three seconds.

6. Is it necessary to wet all the coffee powder in the first place?

Either is fine, but I don't recommend putting the coffee powder in the middle of the curling kettle after it is wet. Because of the humidity, it is difficult to make the coffee powder column form a uniform density. Impatient friends can put powder into the curling kettle, first inject a lot of cold water, infiltrate the entire column of coffee powder, and then adjust the dripping speed of ice droplets.

Finally, let's summarize the difference between Cold Brew and Dutch Coffee through a table.
