Cast Iron Tetsubin Teapot
Cast iron with an enamel lining, which is the detail that matters: unlined iron rusts and alters flavour, enamel-lined does not. Exceptional heat retention suits black and dark teas that want sustained temperature; too hot for delicate greens.

What it does
- Enamel-lined interior
- Very high heat retention
- Suits black and dark tea
- Hand wash only
Who it suits
- gongfu brewing, where short repeated steeps need a vessel you can pour off fast
- anyone moving past bagged tea and wanting to taste a leaf change across infusions
Who should skip it
- a large pot of tea for several people — this is small-format ware
- unseasoned clay if you drink several different teas; porcelain does not hold flavour between them
The thing worth knowing
Unglazed clay absorbs and returns aroma, so a clay pot is usually dedicated to one tea type. Porcelain and glass stay neutral and are the safer first purchase.

What we have not done
We have not independently tested this product. The description above is compiled from the manufacturer’s published specification and from what the category demands, and it is written to tell you who the equipment suits rather than to sell it. Where we have no first-hand experience, we say so rather than inventing a star rating.
