1. Can drinking black tea nourish the stomach?

Compared to unfermented and semi fermented tea, black tea has a mild nature, relatively weak irritability, and a sweet and smooth tea taste.

After sufficient fermentation, tea polyphenols can be converted by polyphenol oxidase to produce theaflavins, thearubigins, etc., forming the unique flavor of black tea. Moderate consumption of black tea can reduce the burden on the digestive system, but it does not have the effect of nourishing the stomach.

2. Will drinking black tea cause internal heat?

Black tea belongs to fully fermented tea, with a mild temperature and can be consumed all year round. If you crave freshness and do not let black tea go through annealing, or if you have a hot constitution and drink a large amount of black tea, you may experience symptoms such as sore throat or constipation.

3. Is the redder the red tea soup, the better?

In black tea soup, theaflavins, thearubigins, and theaflavins are the core substances in black tea, and the optimal ratio of the three results in the best quality of black tea.

Theaflavins: the bright part of color adjustment

Tea red pigment: gives tea soup a "red" color, too high can damage quality, and too low tea soup concentration is not enough

Tea brown pigment: the main reason for dark soup color.

4. Is the thicker the black tea, the better?

Black tea is sweet and warm, which can nourish the body's yang energy. However, it is not recommended to drink it too strongly because tea contains more tannic acid. Tea with too much concentration contains more tannic acid, which can easily affect the digestion and absorption of nutrients in the body.

5. Can I drink black tea at night?

Black tea can be consumed at night: it is generally believed that green tea has a refreshing effect, while fully fermented black tea, when consumed before bedtime, will not affect sleep. In fact, this is not the case because caffeine has strong stability, and tea leaves are basically not affected by high temperature, humidity, or even microbial effects during processing.

Studies have shown that many varieties of black tea have higher levels of caffeine than green tea. If you drink too much black tea at night, it can easily affect your sleep quality, and long-term consumption can actually have adverse effects on your health.
