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 belongs to 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.

For specific style differences, please refer to the table above:

Production principle

Cold-extracted coffee is produced by slow extraction after mixing coffee powder and ice water in a certain proportion. The coffee produced by cold extraction process has a low sense of acidity, low temperature and long contact with coffee powder, so that only small molecular flavor substances, such as flower and fruit flavor, are extracted, while those with larger molecules, such as smoky flavor, are difficult to extract.
