What's the difference between iced coffee and cold coffee?

To put it simply, iced coffee is made by cooling hot coffee, while cold-extracted coffee is extracted at a low temperature without heating. And because cold-extracted coffee needs to be extracted at low temperature for a long time (generally speaking, it takes 12-24 hours), the price of cold-extracted coffee sold outside is generally on the high side (take Starbucks as an example, the price of iced coffee Grande is 110yuan and the price of cold-extracted coffee is 140yuan for the same size). Low-temperature extraction also makes cold-extracted coffee have a unique flavor, and different extraction methods of the same beans can produce completely different flavors. Even because the oil of coffee is rarely extracted at low temperature, ice-drop cold-extracted coffee can generally be preserved for two weeks, and with the preservation time, after fermentation, the coffee tastes more charming, and it can even taste wine!

Cold-extracted coffee is extracted at low temperature for a long time to preserve the original flavor of coffee!

Is there any difference in the flavor of cold coffee?

The extraction process of coffee is generally extracted at high temperature, which will make the tannic acid in the coffee decompose into pyrouric acid, resulting in a sense of bitterness and acid. However, cold-extracted coffee can be reduced by about 67% in this respect than high-temperature extracted coffee because of low-temperature extraction, and in low temperature, water has been in contact with coffee powder for a long time, so that only small flavor substances, such as flower and fruit flavor, are extracted, while larger flavor substances such as tobacco and roasting flavor are difficult to be extracted, so cold-extracted coffee can drink more of the flavor of coffee beans. It tastes smoother, the hierarchical flavor is obvious, and it is obviously sweet.

Cold-extracted ice-drop coffee can show that the original flavor of beans is obvious, and the flavor is smooth and sweet.

What is cold coffee?

Cold extracted coffee, known as Cold Brew Coffee in English, is made of ground coffee beans soaked in cold water for at least 12 hours and filtered by professional utensils. If the alcohol thickness is higher, the time can also be extended to 24-48 hours. Generally speaking, the process of extracting coffee at low temperature is cold extraction. Low temperature and long extraction time are the two main characteristics of cold extracted coffee.

Cold extracted VS ice droplets

Many people often confuse cold extract with ice droplets. It is also iced coffee. The taste and production process of these two kinds of coffee are very different. To put it simply, the cold extraction method belongs to the immersion type, while the ice droplet is the percolation type.
