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
- keeping tea hot at the table through a long sitting
- heating water on a hob, where the maker says the pot is made for it
Who should skip it
- anyone who wants a light pot, because cast iron is heavy when full
- anyone unwilling to dry it after every use, since iron can rust
The thing worth knowing
Check whether the inside is enamel-lined or bare. An enamel lining suits brewing leaf tea, while bare cast iron is traditionally used to heat water, and it should be dried after use.

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.
