Benefits of Cast Iron Teapots

Why Cast Iron?

Cast iron cookwares, including teapots, have been used for centuries. With the introduction of cookware made from new materials hitting the market, people started discarding their cast iron cookware in favor of the new and supposedly ‘improved’ cooking products. However, nowadays you will see a trend of people going back to the old ways. With people suffering from different deficiencies and diseases, doctors and health gurus are recommending going back to the way of life of our forefathers. This includes cooking and brewing tea in cast iron cookware.

You may be thinking how old-fashioned cast iron cookware is but, there is a reason why everyone is going back to filling their kitchen cabinets with cast iron cooking products. Even in the modern kitchen, this dependable cookware has more benefits than any other cookware available on the market today.

Cast Iron Teapots Last Decades

There are people who have been using their cast iron teapots for generations, going back as far as the 1850s. These teapots, if taken care of properly, can stay in excellent shape and perform at their best for your children, your grandchildren and even your great grandchildren.

Chemical Free Teapots

Another major benefit of cast iron teapots is that because they are made from pure cast iron, you are able to avoid harmful chemicals that come from teapots made with other industrialized materials.

Pumps Your Tea with Iron – Beneficial for Iron Deficiency

Iron deficiency is the most common deficiency in the world today. This is a problem that was never faced by our ancestors centuries ago. Because people in the old days cooked and brewed tea on cast iron cookware, their teas and foods were infused with iron that was leached into them by the cast iron pans and teapots.

A study by the American Dietetic Association has found that when using cast iron teapots, a good amount of iron is leached into the boiling water. This results in the tea brewed becoming infused with iron and the person drinking tea will receive a boost of iron, minerals and nutrients. People with iron deficiencies can greatly benefit from this effect.

Why Choose Cast Iron Teapots

A Traditional Way of Brewing Tea

Those who are not really into the art of tea making will not realize how important a part is played by some of the little things they overlook, such as temperature, steeping time, the equipment, quality of the loose tea leaves and the quality of the water. When it comes to brewing your favorite tea, finding and using the the right tools is important. As all tea lovers are aware, the secret to having that delightfully perfect cup of tea is to know the right method of brewing and that requires the right equipment.

Better Heat Absorption – More Nutrients Extracted

Another reason why you should buy a cast iron teapot is cast iron absorbs heat evenly, ensuring the water heats up steadily over time.

This not only gives the tea a pronounced flavor, but the healthy nutrients from the tea leaves are also extracted and bonded with the water.

When compared to ceramic and clay teapots, cast iron is able to retain heat more effectively. This way, you can keep your brewed tea warmer for as much as an hour. Cast iron teapots are more durable than ceramic or clay as well. If dropped, ceramic and clay teapots may shatter into bits whereas cast iron will not. If properly cared for, your cast iron teapot will last you a lifetime!

  1. what is a name of an unlined cast iron teapot. I do not want emamal lined pots. I want to use this on my stove top.

    1. Hi Barbara. There are also non-enamel-coated iron teapots. I know exactly what you mean about iron teapots you can use on your stovetop. My suggestion is to search on google for the keywords “non-coated iron tea kettle.” I will do some research and add any relevant recommendations.

  2. I have used my Japanese teapot daily for several years. I clean it only with water and a cloth. But recently the inside has been producing a black,, temporary stain when I clean it. Where does this stain come from? Is there an inner coating that is coming off after 5-8 years of use? Is it safe to go on using it?

    Please advise. It’s by far the best of my teapots and I hate to stop using it.

    E. Barish

    1. Hi Evelyn. I haven’t heard of this or experienced with any of my Japanese teapots. I do sometimes notice a slight dis-coloring, but this is typically attributed to general use over the years (similar to the pantina you’ll sometimes see develop on an frequently-used porcelain tea cup). I would suggest checking with the maker/manufacturer, especially with regards to your question about it being safe for continued use.

  3. In the explanation of Cast Iron teapots it mentions that while brewing the tea the added advantage is that you get the iron from the teapot. How is that possible if the teapot has an Enamel coating on the inside?

    1. Thanks for pointing that out Tbear…you are correct. This would be the case for non-coated teapots. I will make a note of this and clarify in the blog post.
