Tea's civilization is the civilization of brewing tea with hot water. Although cold brew tea has appeared on the historical stage, it has never become mainstream.

The brewing temperature varies by tea type. For Oolong tea, it must be brewed with water boiled three times at 100 degrees. So, what are the merits of cold brew tea?

Sweet and not bitter When steeped for a long time at room temperature or cold water, the theine and caffeine in tea leaves, which cause bitterness, are not easily released. In contrast, sweet-tasting amino acids dissolve more easily. Therefore, cold brew tea is sweeter and less bitter.

Stomach-friendly Tea with low caffeine content reduces the burden on the stomach wall and can alleviate issues for those with poor stomach function.

Does not affect sleep When brewed at low temperatures, caffeine in tea is not easily dissolved, thus it is less likely to disturb sleep.

Other health factors Tea contains beneficial components such as tea polyphenols, fiber, vitamins, and various minerals. High-temperature hot brewing can easily destroy fiber and vitamins, while low-temperature cold brewing better preserves the essence of the tea leaves.
