I used only 8oz of water this time, to the same leaves. Still 70c temperature but bumped to 3 minutes instead of 2.
The result is much more what one would expect, so I think I just flooded the first batch. 2 minutes 30 seconds might have been better, though.
The notes I gave before still apply, they are just much more present in the cup this time. There is a creeping bitterness here that is not unexpected in a second steeping.
