Many people think that the caffeine content of ice drop coffee is low, because the lower the water temperature, the less easily caffeine dissolves (the lowest temperature of caffeine dissolution is above 80 degrees Celsius). However, the low amount of caffeine extracted by cold water should not be underestimated after a long period of extraction, so some people think that the caffeine content of ice drop coffee is higher, and many experimental results have confirmed this claim. The caffeine content of ice drop coffee varies greatly depending on the coffee beans used in different cafes, the water dripping interval and the total extraction time, so people who are sensitive to caffeine have better drink low caffeine coffee than ice drop coffee.

Mellow wine in coffee

Ice drop coffee is the coffee that is drunk after being refrigerated and ripe, so it is also called "mellow wine in coffee". Even the ice drop coffee extracted under the same conditions varies greatly in taste because of different ripening periods. Under the same conditions, the extracted ice drop coffee is ripened in one day, one week, two weeks and one month, respectively. After blind testing, it is found that the taste and aroma of different ripening time are different, even the personal preferred ripening period is also different. During the ripening process of ice drop coffee, the molecules of coffee ingredients become larger and will be more palatable than when they were first extracted. Over time, the composition of the coffee stabilized and the taste gradually developed, but after two weeks, the coffee began to lose its taste, the flavor was mediocre, and began to sour for more than a month. It is generally believed that the ice drop coffee cooked for a week tastes the best, and the preservation period of the ice drop coffee is usually set at one month. In order to keep it fresh, it must be refrigerated in a sealed container. Each bottle cap switch will allow mold in the air to enter the coffee liquid. Drink it as soon as possible after opening.

Ice drop coffee can only be cold?

The ice drop coffee sold in most cafes is a cold drink, because heating will make its aroma volatile, but can not feel the unique aroma of ice drop coffee. Another way to drink is warm drink, as long as the ice drop coffee solution into warm water, or water heating, can reduce the aroma volatilization to a minimum, feel another charm of ice drop coffee.

Drip type vs immersion type

Usually, the ice-drop coffee is extracted by letting the water drop down. Compared with the immersion type, the extraction apparatus is more expensive, and the extraction method, cleaning and storage are very troublesome, but the extracted coffee tastes cleaner than the soaking type. The aroma is richer. On the contrary, the utensils used in immersed ice drop coffee are cheaper, easier to use, easier to clean and keep, but there may be bitterness and peculiar smell due to excessive extraction, so mastering the extraction time is the key. No matter the drip type or the soaking type, the coffee is extracted with cold water. Compared with the coffee extracted with hot water, the coffee has less oil and fatty acids and is less harmful to the stomach and intestines.
