Now we have very tendious process, which reguired us to make tea at cauldron put new tea in teapots, and then from teapots into barrels, no idea how hard would be to implement something like: puting tealeaves into cauldron, and waiting to turn water into tea,
even if it takes time, and you lose some water in process of boiling, i think it still would be easier to make and more natural.
that process can also make some leftover dregs which can be use as quick curio
