Similar to Yixing Zisha teapots, Zisha tea canisters are the premium tea storage, especially for teas such as Pu-erh tea which requires oxygen for its post-fermentation. Careful preparation for the first time before its use is crucial to avoid the adverse effects of causing the teas to become mouldy or contaminated by foreign odours.
Following are the recommended steps:
- Avoid any detergent or cleaning agents, especially the ones with odours
- Use a wet cloth to wipe off any superficial dust, inside and outside
- Fill half of the canister with warm water, use a cloth (or soft brush if necessary) to brush off any residual dust and clay/earth odour. Repeat this step multiple times until there is no more dust or factory/production odours left in the canister.
- Turn the teapot up side down and dry in the full sun for at least three days. Zisha has natural micro cavities in the clay and is able to store moisture within these cavities. If not dried thoroughly, it will release the moisture into the tea once a tea is stored in it and cause the tea to go mouldy.
