I use that "technique" too mainly during long driving phases of my trips.
ITC sells Yunan TuoCha and bamboo tuocha that are pressed into very dense
tablets. I put one such tablet in this thermos/bottle (this time not on the
mesh, but just inside the thermos and put 140 -ish in it. After an hour of
driving this turns into a delicious drink.
yes, about 3 refills (4 steeps altogether) i.e. 3+ litres of a good puerh
from a 5 g tablet is pretty good by any standards.

All the best,

Sasha.
