It is suggested to choose tea with high fermentation and low irritation for breakfast, such as fully fermented black tea and post-fermented Pu 'er tea.

Breakfast is the first meal after a night's rest. People haven't eaten all night, and their stomachs have just started to work. At this time, if they drink irritating tea, they will feel uncomfortable in their stomachs and even nausea. Black tea and cooked tea are less irritating after full fermentation, and there is no obvious discomfort when drinking some at breakfast. They are also suitable for drinking after meals.
