I just want to make clear what I did last night and this morning, and make sure that I understand clearly what I think that this thread is telling me.
Last night, after making four infusions of tea (five if you count the very first one that got discarded), with the steeping times still very short, I removed the leaves from the brewing vessel (a small yixing pot), and put them in a sealed jar without water. This morning I put the leaves back in the pot, and brewed three more infusions. This morning's tea was no where near "ethereal," and the infusion times were still very short.
So, based on what I think I understood from this thread, I left the leaves in the brewing vessel, and put cold water in it. Either later today or tomorrow morning, I will discard that water and brew more infusions. This process will repeat until the leaves are out of flavor.
Do I understand correctly?
