Surely you have not seen with your own eyes how your tea dries and doesn’t smell…
In China, it’s not uncommon to dry outside on a concrete yard in front of the house (if there’s canvas/mesh under the leaves, it’s a higher level of cleanliness), or maybe just right on the road. When they stink properly (thankfully cars don’t drive over them) they get swept up with a broom into a wicker basket and go on to be processed.
So Chinese teas (Japanese teas don’t come into contact with the outdoor drying area much) pour, pour and pour!
