What’s the Best Cast Iron Teapot?



Cast Iron Teapot

Looking for the best cast iron teapot? Well you are in the right place! I looked far and high for the best one out there, and tried NOT to break the bank at the same time.

Cast iron teapots, known as tetsubin in Japanese, originated in Japan sometime between the 17th and 18th century where they became an integral part of the Japanese tea ceremony.

They have since become popular worldwide. They are traditionally heated using a charcoal fire, but can also be heated on a stovetop.

I use a stove, of course, and find that my glass stove top works just fine. I have also used it on a gas stove, too. I used the smallest burner on the gas stove. If you have mostly big gas burners then you should be really careful when you touch the handle.

Cast iron teapots are very beautiful. Many of these teapots are decorated with interesting and unique patterns and designs. The symbols on the pots often have meanings, such as a dragonfly to symbolize strength and courage.

When cast iron teapots are heated, some of the iron is released into the water.

Make sure only the good stuff get in your tea. See this post on filters for removing fluoride from water.

Obviously, this makes the tea a richer source of iron, but it also adds a flavor to the tea which many tea connoisseurs say enhances the natural flavor of the beverage. (At least, that’s what the folks at Teavana told me – I don’t know if I believe any of that because they also implied that the cast iron teapot cured cancer. Seriously! Maybe there is some study that backs up the claim, but they never cited their sources.)

Be sure to see my post on how to Clean a Cast Iron Teapot.

That’s just a bit of the “magic” around cast iron that people seem to latch on to. I mention that story in jest – but I really love my cast iron teapot and it’s fun to have a little informal tea ceremony anytime of day.

Because of its thermal mass, the cast iron teapot helps keep the water warm longer than a ceramic or stainless steel teapot as well.

You can even use one of these at the office too!

How to use a cast iron teapot at the office

You might think that you can’t use a cast iron teapot in the office or at work. But you can! And here is how…

Benefits of cast iron teapots


It’s no secret that modern advancements and new technology aren’t always what they’re cracked up to be. With unintended health consequences of modern materials, many people are returning to tried and true products.

Additionally, some of the iron from a heated tetsubin gets into your tea. So cast iron teapots enhance the health benefits of your tea by enriching it with this crucial mineral. Giving your body the proper levels of iron level prevents anemia, improves mental performance, and reduces fatigue. So raise a glass to your health. A glass of tea, that is.


Cast iron teapots are made to last. If properly maintained, they can be used for generations. They can become treasured family heirlooms that you can actually put to use. They are also used as a part of the Japanese tea ceremony.


Tetsubins come in a plethora of designs, ranging from the simple and elegant to the ornate. High quality cast iron teapots are constructed by craftsmen, meaning no two are exactly alike. They can be displayed prominently in your home as an expression of your personality and taste. Tetsubins not only lend a touch of class to your tea time, but they also make a great conversation piece!
