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.

Coffee extracted at low temperature has a sweet taste, low acidity and mild bitterness, adding layers after fermentation, as intoxicating as aged 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.

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.

Cold coffee

The concept of cold-extracted coffee is similar to cold-brewed tea. During the extraction process, the beans are ground, injected with cold water, soaked in a low temperature for at least 12 hours, and then filtered out before drinking.

This cold bubble method will magnify the various flavors and aromas of coffee, reduce the acidity, and make the flavor cleaner and purer. The characteristic is that the more cold the drink, the better the flavor. It is more popular in the United States to add equal proportion coconut water, which is more popular in the United States to add equal proportion of coconut water. Each recipe has its own flavor.

Injecting nitrogen into cold-extracted coffee produces dense bubbles, which makes nitrogen ice-drop coffee feel like beer at first glance, so nitrogen coffee is also known as "beer coffee". Bubbles not only smooth the texture of the coffee, but also feel as if cream has been added. Many drinkers feel that it tastes more mellow than the original cold-extracted coffee, even without adding sugar. Innovation in technology and brewing makes iced coffee take on a new look.

Ice drop coffee

Ice drop is the use of ice water mixture below 5 degrees C, let the ice naturally melt through the valve to control the speed of ice water dripping into coffee powder, ice water drops in the coffee powder slowly dissolve the flavor of coffee, dripping a little bit out of the extract, the complete extraction time is about 2 MUL for 8 hours. In order to get a better taste, it will take 12Murray 48 hours of cold fermentation time. The amount of each extraction is very small (usually 30murmur60ml). The concentration is usually very high without ice cubes. If the coffee is too strong, it will be diluted with ice cubes according to your taste. Because of the slow process, ice drop coffee is more expensive, but tastes excellent.

American barista champion Laila once said in an exclusive interview that ice drop coffee has more aroma and more delicate and subtle taste than cold coffee.

What kind of coffee beans are suitable for cold extract coffee?

These are personal preferences, specific what beans are not strictly required, as long as they like it. However, Qianjie coffee is recommended to be sun-treated or honey-treated, so that the cold-extracted coffee is sweeter and more popular.

Qianjie coffee will be made with [Hartman] and [Sakuran] so that you can get a cup of cold coffee with strong fermented flavor.
