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.
