Brief introduction of Ice drop Coffee and its production method

Ice drop coffee, also known as water drop coffee, ice brewed coffee, is a way to make coffee drinks. Ice drop coffee uses ice to extract coffee, which is a slow process that often takes hours, so ice drop coffee is more expensive.

Principle.

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

Special features

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 Manning, because "shallow roasting is sour, deep roasting is bitter but strong", therefore, 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 dripping coffee is not astringent is that cold water is used, and hot water is often used in other coffee brewing, while hot water with too high temperature will break down some chemicals in the coffee and release astringency, while waterdrop coffee is completely filtered with cold water. The coffee is 100% wet, and the extracted coffee tastes smooth but not sour.

Coffee pot

Ice drop coffee maker was invented in the Netherlands, also known as Dutch iced coffee drip filter, 3-4 layers of glass containers on the wooden seat, placed in the glass window at the door, the spectacle with a little mystery. The upper layer of the Dutch iced coffee drip filter is a container of ice cubes, ranging from 500cc to 3000cc according to capacity.

Manufacturing method

Production steps:

1. Grind the special ice drop coffee beans with a 2-3 scale grinder.

2. Put the filter screen at the bottom of the extraction bottle

3. Pour the coffee powder into the extraction bottle and straighten out the coffee powder.

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

5. Prepare ice cubes and filter 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. Adjusting the throttle valve to 40-60 drops per minute is the most appropriate.

8. Finish the production and enjoy.

Extraction secret

1. The ratio of coffee powder to ice water is about 1: 12: 20, which can be determined according to personal preference.

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

3. Because of the long extraction time, it is suitable for eating deep-roasted coffee beans, high-grade pure coffee or ice drop special coffee beans.

4. one of the keys to the success or failure of ice-dripping coffee is dripping filtrate, and a slow dripping rate of about 7 drops in 10 seconds is the best. 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.
