The principle and steps of making ice drop coffee what coffee beans are used in ice drop coffee?

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.

1 principle

The principle of ice-brewed coffee is that the coffee itself is compatible with water and is extracted bit by bit by melting ice. The coffee extracted has different flavor according to the roasting degree, water quantity, water temperature, droplet speed, grinding thickness and other factors.

2 characteristics

Coffee powder is 100% low-temperature soaked and moist, the extracted coffee taste is strong, smooth, rich, admirable, and the flavor is outstanding. Adjust the speed of water droplets, use cold water to slowly drip, with a low temperature of 5 degrees Celsius, leak for a long time, so that the original flavor of coffee can be reproduced naturally.

The advantage of ice drop coffee is not sour and does not hurt the stomach, because using this method to make coffee, most of the coffee beans selected are deep-roasted coffee beans such as Mantenin, because "shallow roasting is sour, deep roasting is bitter but strong", so ice drip coffee is not sour. Another reason for choosing deep-roasted coffee beans is that iced coffee will be diluted with ice cubes, so deep-roasted beans must be selected to filter so as not to be strong enough.

The reason why the taste of waterdrop coffee is not astringent is because of the use of cold water. Other coffee brewing methods often use hot water, while hot water with too high temperature will break down some chemicals in the coffee and release astringency, while the dripping coffee is completely filtered with cold water, and the coffee is 100% soaked and wet. the extracted coffee tastes smooth but not sour.

Method of use

1. Close the droplet regulating valve first.

two。 Pour the right amount of drinking cold water into the water bottle according to the number of users, and add the right amount of ice to make iced coffee. The standard water quantity for one person is about 120CC.

3. Wet the filter cloth filter with water, then put it into the coffee powder cup

4. Put the right amount of coffee powder into the coffee powder cup, and the standard amount for one person is about 10-12g very fine ground coffee powder.

5. Finally, put the pill filter paper on the central surface of the coffee powder (No. 6 pill filter paper for the water drop coffee maker), and the pill filter paper should be placed on the landing point for the water drop under the water bottle.

6. Slowly open the droplet adjustment valve to allow water droplets to flow out of the water bottle, the water droplets should be dripped on the pellet filter paper, the standard droplet speed should be 40-60 drops per minute, and should be adjusted every 2 hours.

7. The water droplets will permeate the pellet filter paper and coffee powder, make coffee, pass through the cloth filter, and finally fall into the coffee liquid container. Cold and delicious, 100% original water drop coffee is finished.

Points for attention

1. Be sure to rinse all glassware and cloth filters with clean water before and after use

two。 Please discard the pellet filter paper immediately after use and do not reuse it.

3. The filter cloth on the filter cloth filter can be reused after cleaning. If the filter cloth is damaged or smells before use, stop using it immediately and replace the new filter cloth.

3 Coffee pot

It was invented in the Netherlands, also known as the Dutch iced coffee drip filter, 3-4 layers of glass containers on the wooden seat, placed in the glass window of the door, magnificent but also with a little mystery.

The upper layer of the Dutch iced coffee drip filter is a container of water, ranging from 500cc to 3000cc according to capacity.

4 production process

Materials

Ice drip filter; deep-baked coffee powder, mineral water, ice cubes.

Production steps

1 special ice drop coffee beans, grind them with a 2-3 scale grinder. 2 put the filter screen into the bottom of the extraction bottle.

Pour the coffee powder into the extraction bottle and flatten the coffee powder.

4 place the extraction bottle on top of the collection bottle, and then place the drip plate on top of the extraction bottle.

5 prepare ice cubes and filtered pure water and pour into the water storage ball at the ratio of 1:1.

6 turn on the control switch to wet the surface of coffee powder evenly.

7 adjust throttle valve to about 40-60 drops per minute is the most suitable.

8. Finish production and enjoy.

Extraction secret

1 the ratio of coffee powder to ice water is about 12: 20, depending on your personal preference.

2 in order to increase the contact area between coffee powder and water, the grinding degree of coffee powder is better between siphon type and filter type.

3 because of the long extraction time, it is suitable to use deep-roasted coffee beans, high-grade pure coffee or ice drop special coffee beans.

4 the ice drop coffee is strong at first and then light, so it is necessary to wait for all the ice water to be dripped before drinking the best flavor.

One of the keys to the success or failure of dripping coffee is the dripping speed, with a slow dripping rate of about seven drops in 10 seconds. Water and coffee powder have a long time fusion, coffee taste is more saturated; if the filtration time is too fast, the taste is too light, at the same time will produce stagnant water overflow, on the contrary, too slow will make coffee ferment, produce sour taste and wine taste.

5 production method

Raw materials: ice drop coffee pot 1; bean grinder 1; round filter paper 1; Gala Minita coffee beans 40 grams; Kenya coffee beans in East Africa 40 grams; Sumatra Mantenin coffee beans 40 grams; boiling water 500ml; ice cubes right amount; full fat fresh milk; fructose

Practice

1. Place the filter in the middle pot to prevent the coffee powder from flowing into the lower pot.

two。 After all the coffee beans are ground to a fine grind (for example, Pegasus must be ground to No. 3), put the coffee powder in the order of Kenya AA → Raminita → Golden Manning, put it in a medium pot and cover it with round filter paper.

3. Place the pot completed in practice 2 on the second floor of the wooden frame (from the beginning of the shelf).

4. After the pot is installed on the first floor, put in ice cubes and boiling water. The ice cubes should be about 9 minutes full.

5. Turn on the regulator of the upper pot and let the round filter paper first. After the filter paper is wet with ice water, change the regulator to a drop rate of 5 seconds to begin to extract the coffee liquid.

6. After the ice water on the pot has been dripped, leave the room temperature for about 3 hours. take out the pot and cover it with plastic wrap and refrigerate it for about 5 hours. [1]

6 self-made tools

As the ice drop coffee takes a long time to make and the price is more expensive, most of the ice drops to the coffee shop need to be booked in advance, and the ice drop coffee can not be seen on the menu of many coffee shops.

In the hot summer, if you want to drink a cold and refreshing cup of iced coffee, homemade at home is a good choice.

There are a variety of ways to make ice drop coffee, depending on which device you choose. Such as the use of royal Belgian coffee pot, Vietnamese coffee pot and mocha pot and so on.
