Long-lasting heat retention – thanks to cast iron construction
Cast iron stores thermal energy and releases it slowly, promoting even water temperature and steady warmth across serving. The mass of the material reduces rapid temperature drop during pouring.
Tea stays hot for longer between pours, useful when serving several people or enjoying a slow afternoon brew.
Cleaner flavour and leaf control – with a fully enameled interior and removable stainless-steel infuser
The enameled interior prevents direct metallic contact with leaves while a removable stainless-steel infuser keeps leaves separate from the liquid for precise steeping. The infuser lifts out for easy disposal of spent leaves.
Clear, less metallic-tasting brews with straightforward leaf removal and simple cleaning after use.
Improved water character – thanks to mild iron ion interaction
Boiling in cast iron can release small amounts of iron ions and absorb some chloride ions, which subtly alters water chemistry. That interaction can make water taste softer and less sharp.
Lighter Japanese-style teas can taste sweeter and smoother, a benefit noted by users who prefer delicate brews.
