How do you make iced coffee? What are the characteristics?

Hot summer, cold coffee is also one of the drinks to relieve the heat. When you walk into a coffee shop, have you ever wondered why the price of iced coffee is so much higher than that of ordinary iced coffee? Of course, ice drop coffee is not just iced coffee with a better name, but its time-consuming extraction process and sweet and mellow flavor are all the reasons why it is so expensive. What's the difference between ice brewed coffee and ice drop coffee? Can you make your own iced coffee at home? We will tell you one by one below.

What is ice drop coffee?

As the name implies, ice drop coffee is extracted by "low temperature" and "slow drop".

Brewing coffee is actually the process of extracting and dissolving the odor molecules from coffee cells (as described in more detail in another article). Generally, the goal is achieved quickly by hot water, while ice drop coffee is replaced by time instead of temperature. use ice water below 5 degrees Celsius to slowly dissolve the flavor of the coffee, and then drip out the final extract bit by bit. The time of complete extraction of ice drop coffee is about 2 to 8 hours, which is adjusted according to personal preference and type of coffee beans.

The characteristics of ice drop coffee

The taste is sweeter: the odor molecules in coffee have a dissolving order, and the aromatic molecules are extracted first, and then the bitter molecules. When brewing coffee with hot water, it often dissolves too many bitter molecules because of improper temperature and time control, so that the taste of the coffee is not good. Ice drop coffee is extracted with cold water for a long time, only dissolves the molecules with good smell, tastes strong and smooth, showing the best original taste of coffee. Being not bitter or sour is the main reason why ice drop coffee is loved by many people. Ice coffee

Storage tolerance: when any food is heated, it becomes perishable because the molecular structure is destroyed. Hot water brewed coffee has a very short shelf life, and the taste begins to deteriorate after being kept for more than 45 minutes. Ice drop coffee is not heated, so its shelf life is very long. After extraction, it can be kept fresh in the refrigerator for two weeks. The fermentation process also changes the taste of the coffee at different levels. Generally speaking, the extracted ice drop coffee will be put in the freezer for 1-3 days before drinking, the flavor is better.

Do not hurt the stomach: many people with bad stomach will stay away from coffee because of the stomachache caused by coffee. Ice drop coffee lacks a lot of stimulating molecules in heat-extracted coffee, and the content of caffeine in the same concentration is also lower, which is a healthier choice.

Ice dripping coffee utensils

Generally speaking, the apparatus for extracting iced coffee is divided into three parts: the upper pot for ice water, the filter for coffee powder, and the lower pot for the final extraction of coffee. The traditional pot has a device like a chemical eyedropper, which makes it easy to control the flow rate of ice water and let it fall on coffee powder at a certain rate.

There are different sizes of ice drop coffee pots on the market, the price depends on the material and refinement, some people will use the principle of their own combination, using two filter cups to make a simple ice drop device.

What is iced coffee?

Some people also call ice-brewed coffee as ice-brewed coffee, but real ice-brewed coffee refers to coffee powder that is put in cold water and extracted after 12 hours like cold tea, so it is also called cold-brewed coffee.

Ice-brewed coffee, like ice-drop coffee, also has the characteristics of sweet taste, non-acerbity and no harm to the stomach. the utensils used are relatively simple and suitable for home-made.

How to make iced coffee at home

Because it takes time to make and usually uses high-quality beans, it's not cheap to drink ice-drop coffee in a coffee shop. If you want to enjoy the flavor of ice-drop coffee at home, we recommend the following options:

1. Buy a set of ice drop coffee pots

This is the most direct way, according to the machine instructions to add water and coffee powder, take some patience and time, you can enjoy delicious iced coffee.

Like brewing coffee, the more uniform the coffee powder particles, the better. Coffee powder particles of iced coffee are recommended, such as the size of fine sugar, the standard ratio of water to powder is 1:15, and the dripping speed is about 1.5 seconds, but all can be adjusted according to personal preference. Before you start dripping, remember to soak the coffee powder evenly with a little ice water to make the extraction process more uniform.

If you want to taste a more complete and warmer coffee, you can seal the extracted coffee in a glass bottle and keep it in the refrigerator for 1-3 days. Wait for the coffee to ferment slightly before tasting it. Medium and light baked beans usually take a long time to develop their flavor.

two。 Self-made ice drop coffee group

Is the ice drop coffee group too expensive? Use a thermally conductive filter cup or funnel (stainless steel or copper) to fill an ice cube as a pot, and a flannel filter cloth and another filter cup with coffee powder to extract the good taste of iced coffee.

3. Ice brewed coffee (cold brewed coffee)

The practice of ice-brewed coffee is different from that of ice-drop coffee, but it still has a sweet taste. All you need is a jar or kettle, put in the ground coffee powder, add cold water at the ratio of 1 to 4.5 water, put it in the refrigerator or at room temperature for 8-12 hours, then pour it out and sift it. The size of the coffee powder needed for ice-brewed coffee is similar to that of ice-drop coffee, and it can be adjusted by itself, but the coarse particles need a longer soaking time.

Ice-brewed coffee is so strong that it needs to be diluted at 1:3 before drinking it. It can also be kept fresh in the refrigerator for two weeks. There is also an ice-brewed coffee maker on the market, which is equipped with a filter screen, which is more convenient to make.

4. Japanese iced coffee (Japanese-style coffee)

Japanese iced coffee is not ice drop coffee, but some people say it even tastes better than ice drop coffee because they believe that some special odor molecules need to be heated to extract. The method is to cool the extract of the hand-brewed coffee directly by placing the cup with ice under the filter cup of the hand-brewed coffee. If you want to save time, it is also an option.

I hope the above information will give you a better understanding of iced coffee. Slow workers can do fine work, ice coffee is like the essence of time extraction, every drop is so precious. Whether it's to relieve the heat or taste fresh, you can't miss the delicious taste of ice drop coffee if you love coffee.
