Cold coffee is popular all over the world. You may have noticed that in many coffee shops, cold coffee is more expensive. Do you want to know why?

In fact, what makes cold coffee more expensive is the time it takes to make coffee. Usually, it takes less than 10 minutes to make some hot coffee, even including grinding time. On the other hand, cold-extracted coffee takes at least three to five hours. Some processes can take up to 24 hours.

Many people distinguish cold coffee from iced coffee because we understand that iced coffee is extracted with hot water and then added with ice or chilled to change the coffee from hot to iced coffee. The biggest difference of cold-extracted coffee is the coffee liquid obtained by low-temperature extraction of ice water used throughout the process.

Although the extraction speed is slow at low temperature, in terms of flavor, low temperature extraction coffee is more mellow and popular because high temperature can easily decompose tannic acid in coffee into pyrowu acid, resulting in acidity and bitterness.

Due to the low temperature of cold extracted coffee, coffee can avoid the emergence of some bad substances, which makes the flavor of coffee chic and unique. Low-temperature extraction can also be easy to store, can be kept in cold storage for 1-2 weeks, over time, it is said that the coffee liquid will slightly ferment itself, when drinking will have a flavor similar to high-quality wine.

The taste of coffee extracted at low temperature will change according to the degree of coffee roasting, water volume, water temperature, droplet speed, coffee grinding thickness and other factors, and the perfect proportion needs to be adjusted by time and experience. Low-temperature extracted coffee tastes sweet, low acidity, mild bitterness, and adds layers after fermentation, but it is also easy to lose the special flavor that has been released at high temperature, so the selection of bean varieties and roasting degree also requires special consideration.

Of course, cold-extracted coffee can also be mixed with the right amount of milk and syrup, these changes are very flexible, but many people who are good at it will still choose the original taste of coffee. in this way, as far as possible will not be a variety of fruit juices, dairy products to cover the flavor of coffee, and lose the true flavor of coffee.

Although the aroma of delicious iced coffee is not as unrestrained as hot coffee, a variety of good taste, aroma and touch come one after another, enriching our mouths and satisfying our hearts. But it is not just iced coffee with ice cubes, but cold extracted coffee slowly extracted from cold water or ice water, subverting the imagination of ordinary coffee and enjoying the mellow flavor and cool pleasure of tasting wine.

When coffee has become a daily drink for many people, in addition to the differences in coffee bean producing areas and varieties, the difference between light and heavy roasting, and the different methods of brewing hot coffee, there is also a kind of pleasure in drinking coffee, that is, cold coffee. On a hot summer day, the fermented aroma and coolness of iced coffee are particularly fascinating.

Cold extraction coffee can be divided into three methods: water drop type, ice drop type and ice brew type. Due to different extraction conditions, these three methods will cause different flavor and taste, but they all belong to cold extraction coffee. The principle of cold-extracted coffee is the same as that of cold-brewed tea, which is to slowly dissolve the flavor of the coffee by soaking it at low temperature for a long time.

Water drop method: extracted with room temperature water and drunk directly, just like mellow whisky.

Ice drop method: extracted with ice water and drunk directly, just like a refreshing cocktail.

Ice brewing: put the extracted coffee into cold storage and fermentation, or soak the coffee powder at room temperature and put it into cold storage to ferment, just like an old girl red.

Filter tea bag soaking method: soak in cold water like tea bag, put it into cold storage and fermentation, just like refreshing cold tea.
