What are the flavor characteristics of cold extract coffee? how to drink it? how to make cold extract coffee? hot water or cold water?

In the hot summer, to a cup of iced coffee, it can be described as refreshing, but now that it is autumn, iced coffee will still be so popular? Qianjie told everyone: this is necessary! Because although the weather is in autumn, the temperature is still there, the taste of iced coffee is still there, and friends who like this taste are still in love with it as always.

Of course, at first, many friends may not know that coffee can also be brewed with cold water, because what we usually drink is coffee extracted at high temperature, that is, the roasted coffee beans are ground into coffee powder of a specific thickness, and then the taste of the coffee is extracted with water. High temperature extraction will decompose the tannin in the coffee into pyrosylic acid, resulting in bitterness and sour taste.

But Qianjie tells us that the coffee brewed in cold water has a different taste. And very popular! Why? Because cold-extracted coffee is extracted at low temperature, when it comes into contact with coffee powder for a long time in low-temperature water, only flavor substances with smaller molecules, such as flower and fruit, are extracted, while flavor substances with larger molecules, such as smoking and roasting flavor, are difficult to extract. therefore, cold-extracted coffee is more able to drink the flavor of coffee beans, and the taste is smooth, hierarchical and sweet.

In front of the street, let's take a look at cold-extracted coffee: cold-extracted coffee has become more and more popular in the United States in recent years, so we all know that coffee doesn't have to be hot. It can also be extracted by soaking or dripping in cold water. As for Europe, it may be a while before they begin to fall in love with this new power of coffee. Cold-extracted coffee is also called cold-brewed coffee. Only ice water and coffee powder are involved in the whole extraction process, and the finished product is more pure. So cold coffee itself can fully reflect the subtle taste characteristics of coffee, due to the mild acidity of coffee, so sweet taste, bright taste, soft taste, and with a hint of fruit flavor. In the front street coffee, cold extract coffee is very popular with friends, sitting in the coffee shop, stop this hasty pace, enjoy the delicious coffee!

There are two main reasons for the rise of cold-extracted coffee. On the one hand, the younger generation prefer mild-flavored coffee and are less receptive to traditional espresso; on the other hand, mild coffee is more in line with the concept of health and health. Cold-extracted coffee has a lower bitter taste and has a mild sweet taste, which means that cold-extracted coffee does not need to be seasoned with extra sugar or dairy products.

Cold extracted coffee

Where did the cold coffee come from? Qianjie learned that it was the Dutch who first came up with the cold extraction method, and then spread it to Japan. At that time, the Dutch would ship coffee back to Europe from the colony of Indonesia, and invented a way to make cold coffee because there was no hot water on board. Interestingly, at that time, people thought that cold coffee was mild and did not hurt the stomach, but they did not know that hot water would extract more acid from coffee, while cold coffee was less sour.

Making coffee with ice water or cold water can be traced back to Japan, commonly known as "Kyoto Wind Coffee" (Kyoto-style coffee). The method of cold water extraction of coffee was very popular in Kyoto at that time, so it was named. As early as the 17th century, the Japanese began to use cold water with different cold extraction methods to make coffee, and they would use follicles or dripping methods to make coffee. This method and method of extraction has evolved to this day. There appeared like the most fashionable ice drop coffee pot with the same design as the boutique.

We often talk about cold extraction coffee, then how many degrees of water to extract is more appropriate? Qianjie tells us that cold-extracted coffee is made of water at room temperature or lower temperature, the water temperature is usually lower than room temperature, about 20-22 ℃, due to the low water temperature, the coffee making process is very long, usually takes 12-48 hours. Cold extraction can only extract some small molecular substances, such as flower and fruit flavor substances, while smoking and baking macromolecular flavor substances are not easy to be extracted, and the sour taste will be reduced a lot. However, the most deadly thing about this kind of extraction is its weak ability, which requires water to come into contact with coffee powder for a longer time.

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

In fact, ice drop coffee is also a kind of cold extraction coffee in theory, and ice drop is extracted drop by drop. Ice drop coffee is also known as Dutch coffee or Beijing coffee. Cold water or ice water is also used to make ice droplets, but unlike cold-soaked coffee, ice droplets are made by slowly infiltrating the coffee powder with water. In terms of production time, the production of ice droplets only takes about 5 hours, which is about half of that of cold bubbles. American barista champion Laila once said in an exclusive interview that Qianjie thought that ice drop coffee (Ice-drip) was more fragrant, delicate and subtle than Cold Brew.

Which tastes better, cold coffee or iced coffee?

In the front street coffee, whether it is cold extract coffee or ice drop coffee, are ground and brewed with selected boutique coffee beans.

[cold extraction coffee] requires coffee powder, combined with ice water to soak, take out coffee powder bags at the end of extraction, or filter coffee powder, due to the combination of the whole process, the extraction of coffee can be considered relatively sufficient and rich. In the whole process, only cold water comes into contact with coffee powder, the variable is relatively small, and the taste is relatively stable, so this is also the cold extraction method commonly used by coffee chains.

[ice drop Coffee] although it uses the same ice water conditions, it is more like a retro clock dripping ice water into the coffee powder on the bar of a cafe. The biggest difference with cold bubble is: on the one hand, the contact time between each drop of water and coffee powder is shorter; second, in the process of ice drop, coffee has more contact with air, and the mild oxidation process will bring some uncontrollable factors to coffee.

Therefore, the flavor of the front, middle and back stages of the ice drop coffee extraction is completely different, so the taste of the extracted coffee is as clear and layered as a small freshness. Although it usually takes only 5-8 hours for ice droplets to make coffee, you can put the coffee into a smell-free freezer and let it develop steadily overnight, with unexpected aromas.

As for some people ask which taste better cold coffee or ice drop coffee, in fact, Qianjie thinks: these two kinds are good, cold extract coffee is more rich, ice drop coffee is more clear and hierarchical, and everyone's taste is different. it depends on what you like!
