A new Yixing teapot arrives with dust from the kiln and the workshop still on it. The clay is raw and slightly absorbent. Everything you do in the first few weeks decides what the pot tastes like for the next twenty years.
What seasoning is actually for
Unglazed zisha is porous. The first brews leave aromatic oils in the surface of the clay. Over months those oils build into what collectors call bao jiang — a sheen and a faint memory of the teas you drink from it.
So the goal is not to stain the pot. It is to fill the pores with the flavour you want to keep.
The method
- Rinse, do not scrub. Warm water and a soft cloth only. No soap, no sponge, no toothbrush — detergent leaves residue that the clay will hold for weeks.
- One tea, one pot. Decide now. A pot that makes yancha should only ever make yancha.
- Brew and discard. Fill the pot with that tea, steep it twice as long as you would drink it, and pour it out. Never pour away tea through the pot's own water — rinse the outside while the pot is warm.
- Rest it dry. Leave the lid off until the clay is completely dry. A damp pot in a closed cabinet is how mould starts.
- Repeat for a week. Four to six sessions is usually enough for a modern zini pot. Older or more porous clay takes longer.
What not to do
Do not boil the pot
You will read this on almost every English-language guide. It is a shortcut that does more harm than good: thermal shock can hairline the clay, and boiling drives workshop dust into the pores rather than out of them.
Do not soak it in spent leaves
Leaves left in a damp pot ferment. The sourness stays.
Do not use soap
How to tell it is working
After a month of regular use, hot water poured over the outside of the pot should evaporate evenly and leave the clay looking slightly deeper in colour. That is the beginning of the patina.
The flavour change is quieter: the first cup of a session tastes rounder than the same tea from a porcelain gaiwan.
