Mixing in the pot

astringent.

I would. But, then I got a new pot and didn't need to.

I assume you pour the second cup immediately after pouring the first and that it is not due to oversteeping.

Welcome.

The Asian answer to this problem is simple and eminently effective; simply pour back and forth between two side-by-side cups when you decant - a second or two in one, then without lifting up the pot, slide it over to the second cup. Continue until pot is empty. In this way, you get similar tea in both cups..............................................p*

Yes, give it a stir before pouring because the flavor in the upper region is different from that down around the leaves and you want a consistent taste all the way through.

However, if you're pouring one cup, drinking it, then pouring a second cup, you should also strain out the leaves - decant, if you will - into a second pre-heated teapot before serving the first cup.

Astringency is caused by water that's too hot so, you might also brew it with less-than-boiling water, but stir before altering anything else.
