Why do you need a Japanese cast-iron teapot?

Japanese cast iron teapots come in an array of beautiful traditional and modern designs, such as cherry blossoms and dragonflies. Again cast iron teapots are beautiful, but they are also durable and can last for many years. With the proper care, a cast iron teapot can be an heirloom that you pass down through the generations.

The history of cast iron tea kettles and teapots.

The use of cast iron kettles dates back to the early 17th century when they were first used in traditional Japanese tea ceremonies, called Chadō. These ceremonies are rooted in the Zen philosophy of harmony and inner peace.

Some ceremonies can last as long as four hours and represented the utmost hospitality. Everything is centered on the visual appearance and enjoyment of the tea. Furthermore, the aesthetics of these ceremonies are just as important as the tea. This is why intricately designed cast-iron tetsubins are used.

Benefits of cast iron teapots

Cast iron has experienced a resurgence in popularity because people are learning about the benefits cast iron offers. Cast iron is probably the only piece of kitchenware that improves over time, and cast-iron teapots are no different. Here are some of the benefits of cast iron teapots.

It keeps your tea hot.

Cast iron is heavy. But because of this, the material has good thermal density properties, and it retains heat very well. Compared to glass, stainless steel, and ceramic teapots, cast iron tea kettles maintain their heat much longer. The material also evenly heats your tea, which helps with the brewing process.

Tea tastes better in cast iron.

Many tea experts use cast iron kettles and teapots to make the perfect cuppa. That is because they know that these vessels make for a better tea experience. There are several reasons which are:

  1. The enamel in cast-iron teapots is nonporous, which means teapots do not absorb flavors or smells that unglazed traditional ceramic teapots may do.
  2. Thermal density helps keep water at an even temperature. And it adds to the complexity and character of the tea.

Durable and long-lasting.

Cast iron teapots could potentially last forever if cared for properly. You may never need to buy another teapot ever. Cast iron only gets better with time because they build up character over time. Cast iron teapots are virtually unbreakable and resistant to cracking and also chipping. This is an heirloom that you could easily pass down through the generations.

Enameled teapots do not absorb flavors.

As mentioned earlier, enameled teapots do not absorb smells. When you use your teapot, the only odor that you want to smell is of the tea. Cast iron enameled teapots do not absorb flavors or smell from previous use. And are easy to wash when you have finished. This means that your tea will smell and taste like freshly steeped tea.

Classically stylish and beautiful.

Cast iron teapots that are designed after traditional Japanese tea kettles have beautiful designs. And these teapots are loved as much for their appearance as their practicality. They offer a stylish way for you to enjoy a cup of tea and make it feel like a special occasion. Also, cast iron teapots come in a variety of vibrant shades and colors to choose from.

Japanese teapots are called Tetsu Kyusu in Japanese. These traditionally styled teapots are lovely pieces to display on your kitchen shelf or bench. Teapots are great for get-togethers and special events too. You can make great-tasting tea, and your guests will love your teapot.

A good value.

Getting the most from your cast iron teapot

Now that you know the benefits of a cast iron teapot. How do you get the most out of yours? Here are some tips.

Know the different types of cast iron tea kettles

There are two types of Japanese cast iron tea vessels used to make tea.

  • A tea kettle (Tetsubin)
  • A cast iron teapot (Tetsu Kyusu)

You must use the correct cast iron tea vessel for the right job — because you could end up damaging your teapot from incorrect use. Therefore to get the most out of your cast iron tea kettle, it is good to know which one you have.

Tetsubin

Tetsubins or traditional Japanese tea kettles are used to boil water. These tea kettles are similar to antique Japanese water kettles. And also like the ones used in the Victorian era. They are entirely cast iron and feature a built-in swing handle. These tea kettles were heated directly over charcoal fires in many homes until the 20th century. Tetsubins can typically be used on gas stovetops and ceramic burners.

Tetsu Kyusu

Not to be confused with Tetsubins, cast iron teapots — or Tetsu Kyusu — have an enamel glaze on the inside. These are the modern versions of the classic Tetsubin. Enamel was added to prevent rust, and the size is reduced for practical use. Most Japanese teapots have an infuser, which is a device where you place loose tea leaves. Infusers serve the same role as tea bags and make clean up easy.

Cast iron teapots should never be used to boil water for tea. You should only use them to brew tea. Likewise, they cannot be used over an open flame or on the stovetop as they could crack.You can learn more about the differences between the Japanese kettles and teapots with this article.

How to brew tea in your cast iron teapot in 6 easy steps

Boil water
First, boil the water. Ideally, you should use a Japanese kettle to boil water.

If you do not have a tetsubin, then boil water in a pan or kettle.
I would avoid plastic-lined kettles if you can.
These kettles can negatively change the taste of the water.

Heat your teapot

Next, preheat your teapot.
Pour warm water in your teapot and let it sit for two minutes, and discard the water.

Add loose tea leaves

Then place loose tea leaves into the infuser of your cast-iron teapot.
I use the old-fashioned method of one teaspoon per cup as a general rule.

If your budget allows, try a traditional Japanese Sencha loose leaf tea.
However, if you are new to tea drinking, then a sampler pack from Tea Forte
Tea Forte offers a variety of teas from around the world.

But my favorite is tea Lady Grey from Twinings. Links take you to Amazon if you are interested.

Only fill the infuser about halfway as the leaves will expand. This will allow for more efficient brewing.

Add water

After the water boils, add enough to the cast iron teapot to submerge the tea leaves.

I recommend using approximately 200ml of water per one teaspoon of tea leaves.

Steep
Next, place the lid on the teapot and allow enough time for the tea to steep.
For steep times, check out the instructions that came with the tea that you are using.

Let the water cool a bit first if you are using green tea.
It tastes best when brewed at lower temperatures.

Green tea also requires shorter brew times.
Try not to steep green tea for longer than 3 minutes.
Black tea requires longer steep times and higher temperatures.

Pour and enjoy

Lastly, to prevent the tea from becoming bitter or acidic.
Immediately pour it from the teapot or remove the infuser and enjoy.

How to take care of a cast-iron teapot

To keep your cast iron teapot in good shape, you should use and care for it the right way. Here are some tips to ensure a lifetime of use.

First use

Before using your cast iron teapot for the first time, rinse the pot with boiling water and then dry thoroughly.

After each use

After each use, make sure you do the following:

  • Allow the teapot to cool before drying.
  • Next, rinse the pot out with warm water.
  • Try not to use harsh soaps or detergents.
  • While the teapot is still warm, wipe the outside with a clean, dry cloth.
  • Turn the teapot upside down and allow it to air dry with the lid off.

General care tips

Here are some general care tips:

  • Polish the surface of your cast iron teapot with a tea-soaked cloth. This will help prevent rust, and it will also keep it looking glossy.
  • Remember, if your cast iron teapot has an enamel lining inside, it should never be used to boil water. Otherwise, you might crack the enamel.
  • Hot iron could stain countertops and other surfaces. So, always place your teapot on top of a trivet.
  • You might notice water marks or spots on the bottom of your teapot after a couple of weeks of use. These spots are caused by a buildup of minerals.

Don’ts:

Here are some things that you shouldnotdo when it comes to your cast iron teapot.

  • Use harsh chemicals to try to remove rust. These cleaners are toxic and can damage the metal.
  • Above all, do not put a cast iron tea kettle in the dishwasher.
  • Pour cold water into a hot cast iron tea kettle. Pronounced changes in temperature can cause stress fractures due to the iron expanding and contracting.
  • Place a cast iron teapot over an open flame or use it on the stovetop. It could crack the enamel.
  • Allow your cast iron teapot to come into contact with salts or oils.

How to restore a vintage cast iron teapot

If cared for properly, cast iron kitchenware will last forever. Both cast iron tetsubins and vintage enameled cast iron teapots that are damaged can rust if exposed to water for a while. Leave standing water in a cast iron teapot, and the next time you go to use the teapot, you might notice some rust.

Are you wondering if your teapot is still safe to use even if it has rust? There is no need to go out and buy a new cast iron tea kettle just because it has a layer or two of rust flaking off. It is perfectly safe to still the kettle. Interestingly some tea connoisseurs like to drink tea from a pot with some rust. Because the rust enhances the taste of the water.

However, if you’d like to restore your vintage cast iron teapot to its former glory, you can do so— even if it has a pretty thick layer of rust. With a little TLC, your teapot will look brand new. Here are detailed instructions for restoring your tea kettle.

Remove rust from your vintage teapot in five easy steps.


Remove surface rust

Firstly, use a small wire brush and lightly spot brush the rust by hand.
You can also use a Brillo, SOS, or another abrasive scouring pad.
However, brush gently to prevent scratching, especially on the enamel.

Add tea

Next, fill the pot with used green or black tea leaves.
Make an extra-strong brew of tea.

Add boiling water

Add boiling water which releases tannins from the leaves.

Steep

Then, allow the brew to sit and cool for at least 20 minutes.
The tannic acid will react with the rust and form a natural seal.
This helps to prevent rust from coming back.

Discard tea

Finally, discard the tea and rinse and make sure the teapot is completely dry.

What if the above doesn’t work?

If you have heavy iron deposits on your cast iron teapot, then you might try these tips:

  • Try a 50/50 solution of white vinegar and water. Let the solution sit for a couple of hours so that the mixture can get to work.
  • If the vinegar solution does not work. You can also try scrubbing the tea kettle with a paste of baking soda and water.

Final thoughts

A cast iron teapot is a fun and durable kitchen tool that can last for ages with the proper care. But most importantly, choose your favorite flavor of tea and get brewing. And enjoy your teapot.
