The tea is so delicious, and we wrote this article to pass on everything we’ve learned. By the time you’re done, you’ll know how to use a cast iron kettle and be able to choose the one that’s right for you.

What is the difference between a Teapot and a Tea Kettle

The two are sometimes referred to interchangeably; however, a teapot generally is used for steeping tea or coffee, serving or pouring tea. A tea kettle is designed for higher heat temperatures or applications and is used for heating, boiling water, and brewing tea. Used together, a tea kettle and teapot can make for a delicious and refreshing cup of tea, green tea, herbal tea, or coffee.

Using a Teapot

Cast iron requires special care, as anyone with this type of cooking equipment can verify. Proper seasoning and cleaning are a must. The steps for seasoning and proper cleaning prevent rust and odors while improving the taste of tea. Using a cast iron kettle is no different. The process is much easier than caring for cookware.

How to Use a Cast Iron Teapot

  1. Fill your teapot or tea kettle with drinking water
  2. Bring your cold water or warm water to a boil
  3. Let the water cool to the desired temperature
  4. Measure your tea leaves and put them into your infuser
  5. Place the infuser into your teapot and let the tea steep
  6. Remove the infuser and set it aside
  7. Pour your tea and enjoy!

How To Season A Cast Iron Teapot Interior

Just like cast iron pots and pans, cast iron teapots need seasoning before they’re used the first time. Mercifully, this only takes 3 steps and does not take a long time.

  1. Add 5 to 10 grams of tea leaves to water and boil water for 10 to 20 minutes
  2. Pour the hot water out of the teapot
  3. Repeat boiling with water 2 to 3 times until the water runs clear
  4. Leave the lid off your teapot to allow leftover water to evaporate
  5. Let your teapot dry. You are now ready to start making tea !

How does this season a cast iron teapot? The tannin or tannic acid from the tea leaves and the iron from the kettle react to form a film over the cast iron. This protects the kettle from rust.

How to Clean Cast Iron Teapot

Cast iron tea kettle rust can occur if you don’t clean your kettle correctly. Luckily, cleaning a tea kettle is easy.

First, pour out the remaining tea and rinse the inside of the kettle or teapot with warm water and optionally a soft brush. Then, wipe the outside of the teapot dry with a clean cloth but also a soft cloth. Finally, remove the lid and allow both the lid and pot to air dry. Voila! Clean.

Check out these additional tea kettle cleaning steps. Even the laziest tea drinkers can manage!

Can You Put A Cast Iron Teapot on Stove Tops?

Tetsu Kyusu vs Tetsubin

Cast iron teapots come in two varieties. Tetsukyusu or Tetsu Kyusu is not for boiling water and should only be used to brew tea. Tetsukyusu has an enamel coating on the inside and can’t be used on the stove or over flames. The heat could potentially cause the enamel to crack; therefore, this teapot style is only to steep tea. The other teapot Tetsubin is 100% cast iron and is best for boiling and steeping. Therefore, this kettle is good to go on your kitchen stove, your camp stove, a charcoal fire, and the open flame of a campfire. A cast-iron teapot is pretty versatile for use with just about any heat source (excluding microwave, safety first). Just push aside the cast iron griddle and pans and make space on your stovetop for your teapot.
