What's the difference between iced coffee and cold coffee? Cold-extracted coffee from the blue bottle coffee (BlueBottle), coffee makers use cold extraction to make coffee, and Starbucks (Starbucks) large-scale promotion, cold-extracted coffee has become a unique attractive coffee category. The popularity of pure iced coffee seems to have declined a few years ago, and has slowly warmed up in recent years. Common cold brewed coffee, iced American coffee, ice drop coffee and so on, although they are all low-temperature products, but the production process and flavor are very different.

Let the unclear fans know the difference between the two kinds of coffee. Cold Brew coffee is injected with cold water into coffee powder and placed in a low temperature environment for about 12 to 24 hours (including coffee powder). The concept is similar to cold tea.

On the other hand, ordinary iced coffee is more monotonous, basically cooling the hot coffee. As the coffee is oxidized to change its flavor (becoming stale) while waiting for the hot coffee to cool, some people suggest using the Japanese method of replacing half of the hot water used to brew the coffee with ice cubes.

The difference in flavor between the two

For many coffee lovers, cold extracted coffee is a very different experience from ordinary iced coffee.

Generally speaking, iced coffee starts with hot coffee, and you can taste more of the original flavor of coffee beans than cold-extracted coffee, which is why Japanese iced coffee is usually more acidity and aroma than cold-extracted coffee. But this does not mean that cold-extracted coffee is not good, although the extraction speed is slow at low temperature, but in flavor, because high temperature can easily decompose the tannic acid in coffee into pyrouric acid, resulting in acidity and bitterness. Low-temperature extraction coffee is more mellow compared to the flavor and is popular.

Compared with ordinary iced coffee, cold coffee has a smoother and smoother taste, even with a bit of chocolate flavor, because cold soaking has reduced the acidity of coffee, making iced coffee have a new look.
