There are many novice coffee houses among our fans, and many people come to ask us with these questions, so today we are going to talk about what is cold coffee and iced coffee, and how it is different from iced coffee.

This article will address your questions:

1. 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 requires low-temperature extraction 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, so low-temperature extraction gives cold-extracted coffee a unique flavor. different extraction methods of the same beans can produce completely different flavors, even because low-temperature extraction is less likely to extract coffee oils. So ice drop cold coffee can be preserved for two weeks, and with the preservation time is long, the coffee after fermentation, the taste is more charming, and even can drink to the wine flavor!

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

two。 Is there any difference in the flavor of the 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 at low temperature, water has been in contact with coffee powder for a long time, so that only small flavor substances, such as flowers and fruits, are extracted. on the other hand, large flavor substances such as smoking and roasting are difficult to be extracted from the extraction area, 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.

3. I heard that cold coffee tastes healthier?

Because the coffee is not extracted at high temperature, the impurities in the coffee are extracted less, so for friends who often drink coffee to cause gastrointestinal discomfort, you can try cold-extracted coffee. He is a little more friendly to the stomach than the coffee extracted at high temperature. In addition, cold extraction is generally slightly lower in caffeine (for example, Starbucks Grande iced coffee contains 225mg, cold extract contains 200mg).

More in line with the health needs of the coffee choice, more importantly, it is more delicious!

4. What's the difference between iced coffee and cold extract?

Ice droplets are also a kind of cold-extracted coffee, compared to Cold Brew directly put water and coffee powder together for 12 hours, ice droplets are extracted drop by drop, also known as Dutch coffee or Jingdu coffee. American barista champion Laila once said in an exclusive interview that it is more fragrant and more delicate and subtle than COLD BREW iced coffee (ICE-DRIP).
