Discover the Difference: Uncoated Cast Iron vs. Enamel-Lined Teapots

Traditional Japanese tetsubin are iron kettles designed primarily for heating water.

Unlike enamel-lined cast iron teapots, which are designed for brewing tea using previously heated water, an uncoated cast iron kettle allows water to come into direct contact with the iron interior.

This traditional construction offers several distinctive characteristics:

Natural Iron Contact

When water is heated inside an uncoated cast iron kettle, small amounts of iron may be released into the water. The amount varies depending on water composition, temperature, heating time, and the condition of the kettle.

Heat Retention

Cast iron's substantial weight and thermal mass allow it to retain heat effectively, making it a valued material in traditional tea preparation.

Traditional Tea Culture

In Japanese tea culture, tetsubin kettles have long been appreciated for their craftsmanship, practical function, and role in the preparation of hot water for tea.

For tea enthusiasts, using an iron kettle is an opportunity to explore another dimension of traditional tea preparation.

How to Use Your Cast Iron Kettle

Heating Water

1. Fill the kettle with fresh, filtered water, leaving sufficient space to prevent boiling over. Do not exceed approximately 70% of the kettle's capacity.

2. Place the kettle on a compatible heat source, following the manufacturer's instructions.

3. Heat the water to the desired temperature for your tea.

4. Carefully remove the kettle using suitable heat protection.

5. Pour the heated water into your preferred teapot or brewing vessel.

Brewing Loose-Leaf Tea

The included stainless steel infuser allows you to prepare tea directly in the kettle.

1. Place the desired amount of loose-leaf tea in the infuser basket.

2. Add water heated to the appropriate brewing temperature.

3. Allow the tea to steep according to its recommended infusion time.

4. Remove the infuser to prevent over steeping.

5. Pour and enjoy.

Important: Do not leave tea steeping inside the uncoated iron kettle for extended periods, as tannins and moisture may affect the iron surface.

Care and Maintenance

Proper care is essential to preserving the appearance and functionality of an uncoated cast iron kettle.

• After each use, empty any remaining water.

• Rinse the interior with clean water when necessary.

• Avoid soap, detergents, abrasive cleaners, and dishwashers.

• Dry thoroughly after every use to minimize rust formation.

• Allow the kettle to cool safely before storing.

• Never leave water standing inside the kettle overnight.

• Store in a dry, well-ventilated location.

• Avoid sudden temperature changes.

• Do not heat the kettle when empty.

A Note About Rust: Because the interior is uncoated iron, some surface oxidation may develop over time. Proper drying and maintenance help minimize rust and preserve the kettle's condition.
