Advisory

Hello,
I wanted to ask about the opinion on the steeping time of tea mentioned earlier in the discussion:
"Generally speaking, the longer the steeping time, the higher the caffeine content in the tea."
I have encountered the opposite opinion regarding black tea (I'm not sure if it applies to green tea as well), which is that the longer it is steeped from 4 to 5 minutes, tannins are released that specifically neutralize the effect of caffeine, and the tea then has calming effects. So how is it, please? If we want to reduce caffeine, should we steep the tea for a short time, or on the contrary, for a longer 4-5 minutes?
Thank you.

The longer you steep the herb, the more substances are released into the liquid; this is a general rule. The fact is that with the duration of steeping tea leaves, not only caffeine is released into the water but also tannins, which do not neutralize the effects of caffeine but complicate its release in the body. This means that the tea will contain a lot of caffeine and tannins, and due to the presence of tannins, caffeine will be absorbed more slowly in the digestive tract, making its effects in the body more gradual and long-lasting (on the order of hours). When preparing tea, it is up to you which method you prefer concerning the goal you aim to achieve by consuming the tea.
