Can. Thermos cups are just not suitable for making tea.

Notes on drinking tea in a thermos cup

1. After brewing the tea, you can put it in a thermos cup, but you should pour it in after the water temperature drops, not when it is hot. Otherwise, the tea leaves will be soaked in high temperature for a long time, which will greatly accelerate the loss of beneficial substances.

2. Also, remember to clean the thermos cup after drinking. Tea scale will accumulate if it stays in the cup for a long time.

How long can the tea in the thermos cup be kept?

Generally, if tea is left for too long, most of the vitamins will be lost, and the proteins, sugars and other substances in the tea will become nutrients for the reproduction of bacteria and mold. Although tea placed in a thermos can block bacterial contamination to a certain extent, it is not recommended to store it for a long time because nutrients are lost and the tea flavor is damaged. It can be left for 2-3 days, but in real life it is recommended to leave it for about a day.

Why is it not suitable to brew tea in a thermos cup?

1. When making tea with a thermos cup, the tea water will remain at a high temperature for a long time and will be trapped in the cup, making it difficult for the tea aroma to evaporate. In addition, a large amount of tannic acid and thealkali in the tea will overflow, making the tea soup too thick and more bitter, and the taste will not be very good.

2. Tea should not be soaked for a long time. The vitamin C in tea will be destroyed when the water temperature exceeds 80℃. Long-term high-temperature soaking will greatly accelerate the loss of beneficial substances, thereby reducing the health function of tea. Therefore, if the tea is kept in a hot thermos cup for a long time, the tea polyphenols, vitamins, caffeine, etc. in the tea are heat-resistant substances. Soaking in hot water for a long time will cause these beneficial substances to not be well absorbed by the human body.

3. If tea is brewed in a cup for a long time, a layer of dirty tea scale will accumulate. If you often use a thermos to brew tea for a period of time, a layer of dirty tea scale will accumulate, and it is not easy to clean. Originally, brewing tea in a high-temperature cup will lose its fragrance. If layers of tea scale accumulate for a long time, it will not only be unhygienic, but also shorten the life of the thermos.
