What is the reason "astringency" feels stronger in a hot tea?

Don't think I qualify to answer this question, as experience is ever
so subjective.

Here are my thoughts going through my mind:

1. Astrigency tends to come out especially in the aftertaste, with a
feeling of dryness.

2. And yes, stronger in hot tea.

3. Especially at the later brews.

4. Some teas have longer aftertastes, with longer astringency.

5. Other feelings come out stronger in hot tea, such as savoriness
(brothiness).

6. The floral overtones tend to more dominant at lower temperature.

My two cents. I am sure the others will have vastly different opinion
and more scientific explanations.

Thanks
i think i didnt express myself correctly
:
why does the tongue perceive the astringency as stronger when in a hot
liquid(tea) than in a cold liquid(tea)?

I do not have the answer to this but I do know that when I take food
out the fridge that was from the night before it does not smell or
taste as good until you re heat it up in the oven. It may be a bit of
science something to do with molecular movement ?ie cold molecules
move slowly and hot move fast , this is just a personal theory

Contraction and expansion. Hot vs. cold.

I don't know, but temperature changes flavours a lot.

For example, when you make ice cream, you have to sweeten the cream mix
more than you would find pleasant by itself, because once it is frozen
it will seem less sweet.

Chilling things kills a lot of flavours. It's why you have to drink
American beer ice cold. But it doesn't kill all of them, so it changes
the overall flavour balance.
