Brewing tea is consider more of an art than a science. However, getting the right tools can actually help you dial in a consistent brew. From holding the temperature constant to the amount of tea. One of the way you can get good tea is by using a Cast Iron Teapot Kettle. Its heavy construction means that it can help maintain a steady brewing temperature. The Best Cast Iron Teapots should resist result and have a relatively comfortable handle.

What are they?

They’re teapots made of cast iron. The Japanese originally popularized this designed and is known as a Tetsubin. Traditionally, it is heated over a sandpit and family and friend will gather around it. They give off warmth and serve tea.

In the states, Cast Iron Teapot are mostly used because of aesthetic purpose. Traditional Tetsubin are beautiful and often time hand decorated. Modern Cast Iron Kettle are usually covered in Enamel Coating to prevent rust and usually have a modern appearance.

Why is a Cast Iron Teapot Kettle Better?

One of the most important thing about brewing tea is steep time. On top of that, the brew time needs to be constant. Since Cast Iron Teapot Kettle are heavy, they can hold heat at a constant rate longer. Where as Glass Tea Pot can rapidly lose its heat and disrupt the optimal brewing temperature.

Cast Iron Teapot Health and Safety

The topic of health and safety always come up with cookware. In terms of health, its no more healthier than other pot. If anything, it will give you more iron in your diet.

Sometimes these pots will begin rust. Rust mostly posed as a danger when it cuts you. I would avoid ingesting it as well, but from my understanding, ingesting it wont harm you. I still recommend avoiding and not doing it.

How to use a Cast Iron Teapot Kettle?

Using a Cast Iron Teapot can be a little challenging if you never used one. Instead of trying to time the temperature, the easiest way to brew tea is to bring it to a boil and wait till the temperature drop. Once it reaches the optimal brewing temperature, put the leaves in and cover.

I recommend that you have specific teapot for different type of tea. The longer you use it, the stronger the flavor is.


When you clean it, I recommend you just rinse it out with water. Be sure to let it air dry. If you can, use a towel to dry it rapidly. The less its exposed to water, while cool, the less it will rust. Models with enamel coating has less of a chance of rusting.
