How to use a Cast Iron Teapot

I understand the excitement of using a new cast iron teapot for the first time. This traditional vessel brews a perfect cup of tea using either loose tea leaves or tea bags.

Here’s my simple, step-by-step guide on how to use cast iron teapot, especially if it’s your first experience.

1. Preheat your teapot

Start by boiling water in a separate pan on the stove. Rinse your teapot once or twice using this hot water. Not only does this help clean your teapot, but it also warms it up, ready for the brewing process.

2. Add your tea leaves

Let’s now talk about your tea preparation. Measure the appropriate amount of tea leaves for every 8 ounces of water, adjusting based on your teapot’s size and infuser. Avoid overcrowding the infuser; allow the leaves space to expand and release their full flavor.

3. Heat and steep

You have a couple of options when it comes to heating your water. If you wish to follow traditional Japanese practice, you can place your kettle over a charcoal fire. However, heat water in another vessel on your kitchen stove for a simpler brewing method and pour the boiling water into the teapot. 

If your teapot lacks enamel, heat water on the stove until it’s the right temperature for your tea (150-180°F for green, 200-212°F for black). Steep according to the tea type’s recommended time.

4. Enjoy your tea!

Now that your tea has become perfect, it’s time to enjoy the best part! Take a moment to appreciate the richness of the flavors, amplified by your cast iron teapot’s unique characteristics.

When using a cast iron teapot, brew just one kind of tea, whether it’s green, oolong, or any other. This builds a flavor-enhancing patina over time. If you’re into loose-leaf tea, consider getting a teapot with a removable infuser for added ease.

By following these steps, you’ll understand how to use a cast iron teapot and enhance your tea-drinking experience.

Cast Iron Teapot Benefits

A cast iron teapot offers durability, enhances flavor, and distributes heat exceptionally well. Its key benefit is its outstanding heat retention, ensuring your tea stays hot for longer, while also enhancing the gradual release of flavors from the tea leaves.

Now, let’s keep reading for more cast iron teapot upsides:


Cast iron teapots, known as Tetsubin in Japan, are incredibly sturdy and durable.

They can withstand the occasional bumps and drops far better than their porcelain or glass counterparts made by other manufacturers like Wedgewood or Waterford.

A few years back, in my San Francisco home, I vividly remember a winter afternoon. While preparing my beloved Oolong tea, a unique Chinese variety, I had a mishap in the kitchen. I accidentally knocked my cast iron teapot off the counter, but to my amazement, it emerged completely unscathed, not a single scratch. That’s when I truly came to admire its remarkable durability.

These teapots, often crafted by renowned brands like Iwachu or Rikyu, aren’t just tough; they’re also visually captivating. Adorned with intricate designs, they add an extra layer of delight to tea time.

Flavor Enhancement

According to The Tea Association of the USA, heating water in an unlined cast iron teapot releases a trace amount of iron into the water. The World Health Organization states that this enhances the tea’s flavor and boosts your essential iron intake for better health.

A noteworthy point to remember is that this benefit is primarily associated with unlined cast iron teapots.

Superior Heat Distribution

The last, but certainly not least is the superb heat distribution of cast iron teapots.

One summer evening, I was hosting a small tea party in my garden in Berkeley, California. According to the National Institute of Health, I made a pot of green tea in my cast iron teapot, which is known for its health benefits. My guests were pleased that the tea stayed hot all evening, so I didn’t have to go to the kitchen to reheat it.

This is because cast iron teapots, like their stainless steel counterparts, heat water faster and retain heat for longer, allowing flavors to develop throughout the pot.

How to clean a cast iron teapot

After each use, let your kitchenware teapot cool fully. Then, clean it and its tea brewing components – the cover and infuser – with warm water only. Avoid soaps or detergents, harmful to such delicate items. While warm, dry the teapot’s exterior with a clean cloth, which is vital for proper appliance maintenance.

How to clean a cast iron teapot

Here’s my quick guide to cleaning your cast iron teapot:

Before use

  • Start by rinsing and warming your pot with boiling water, a technique recommended by many tea experts, including those at the UK Tea & Infusions Association.
  • Remember that cast iron teapots are not designed for stove-top use, so always heat your water separately, whether in a kettle or a saucepan.

After use

  • Allow the teapot to cool down completely.
  • Avoid soaps or detergents, which can harm the delicate enamel lining.
  • Prevent contact with salt and oils and keep your teapot out of the dishwasher, a lesson I learned from a misadventure with my first Iwachu cast iron teapot.
  • Ensure no tea is left in the pot for an extended period, which can lead to rusting. Always rinse it out thoroughly with warm water after each use.
  • Wipe the pot, inside and out, with a clean cloth while it’s still warm.
  • Air-dry it by turning it upside down before replacing the infuser and lid.
  • Rinse the infuser, a stainless steel infuser basket, with or without soapy water – your choice.

Protect your tables and tablecloths using a trivet or pot stand, a tip I picked up after an unfortunate encounter with an oak dining table and a hot teapot.

Don’t stress over rust – it’s non-toxic and, according to some Chinese tea connoisseurs, can add a unique dimension to your tea’s flavor. If it’s not to your taste, a soft brush, a concoction of used tea leaves, and boiling water can help create a natural rust seal within 20 minutes.

Proper cleaning and maintenance extend the life of your cast iron teapot and ensure that every cup of tea, be it a robust Assam or a fruity Darjeeling, is as enjoyable as the last. There’s a reason why cast iron teapots, with their excellent heat retention and durability, are favored by tea enthusiasts and experts alike.

Choosing the Right Cast Iron Teapot

Picking the right cast iron teapot considers four crucial factors: size, design, origin, and the inner enamel coating. Let’s get into the details so you can make an informed choice when buying from tea-specialty stores like Teavana or online marketplaces like Amazon.

Iron Teapot Size

The size matters as it decides the tea quantity you can prepare. Are you a solo tea drinker, enjoying your own afternoon ritual, or do you frequently serve tea to a group, whether guests or family? Your tea habits should guide your decision.

Shape & Design

The teapot’s design, whether it’s a classic Japanese ‘Tetsubin’ style or a modern interpretation, impacts heat distribution, infusion, and your entire tea experience, transforming a casual tea break into an aesthetically pleasing ritual.


The origin of the cast iron teapot provides insights into its quality and craftsmanship. Japanese teapots, for instance, are renowned globally for their traditional manufacturing techniques and high quality, just like other famous Japanese products like Kobe beef or Sake.

Inner Enamel Coating

The inner enamel coating in teapots, like those from Iwachu, is essential. It prevents rust, simplifies cleaning, and enables you to brew different teas in the same pot, from Chinese green tea to Indian Assam.

But if you’re a tea purist aiming for a distinct flavour, such as Matcha or Darjeeling, consider an unlined pot.

In the quest to find the right cast iron teapot, bear these factors in mind. Choosing a pot isn’t just about the pot itself. It’s about finding a tool matching your tea-drinking habits, your aesthetic preferences, and the wide variety of tea organizations like the UK Tea & Infusions Association celebrate.

How a Cast Iron Teapot Can benefit your experience

Alright, let’s delve straight into the tangible factors that make using a cast iron teapot an elevated experience:

  • Design Appeal: The artisanal cast iron teapot designs add aesthetic charm to any setting. Their traditional patterns and motifs can transport you to different times and places.
  • Heat Retention: Cast iron teapots are known for their heat-retention properties. This means your second and third cup of tea remains just as warm as the first.
  • Consistent Brewing: The even heat distribution helps in consistent brewing, ensuring that every cup of tea has the same depth of flavor.
  • Durability: Cast iron teapots are sturdy and durable. There’s a sense of reliability that enhances the overall tea-drinking ritual.
  • Ritualistic Value: Using a cast iron teapot often involves traditional brewing methods, adding a ritualistic value that can be calming and meditative.
  • Conversation Starter: Their unique appeal often sparks conversation, making the tea-drinking experience more engaging and communal.

In essence, a cast iron teapot serves more than just utility; it enriches the tea-drinking experience, turning it into an immersive activity.

How to use a Cast Iron Teapot on Stove

While it’s usually recommended not to heat your cast iron teapot directly on the stove, there are certain situations where you might need to. For example, if you’re using a traditional, unlined cast iron teapot or kettle, often referred to as a tetsubin, it’s perfectly safe – and often encouraged – to heat your water right in the kettle on the stove.

Here’s a quick guide on how to do this safely, ensuring your beloved cast iron teapot remains undamaged:

  • Prevent Dry Heating: Always make sure there’s water in the teapot before you place it on the stove. Dry heating can cause the teapot to crack or the enamel lining (if any) to chip.
  • Use a Diffuser: A heat diffuser can distribute the heat evenly, preventing hotspots that could harm your teapot. This is especially helpful if you have a gas stove.
  • Slow and Steady: Don’t crank up the heat to maximum right away. Instead, gradually increase the heat to allow the teapot to warm slowly. This helps prevent thermal shock.
  • Stay Close By: Never leave your teapot unattended on the stove. It’s not just a safety concern; over-boiling the water can also affect the flavor of your tea.
  • Use Oven Mitts: The handle of your cast iron teapot will get hot, so always use oven mitts or a thick towel.
  • Let It Cool Naturally: Once done, let your teapot cool naturally. Don’t immerse a hot teapot in cold water, which can lead to cracking or warping.

How to Keep Your Cast Iron Teapot

Remember, every teapot is unique and might have specific care instructions, so always check with the manufacturer or retailer if you need clarification.

Preserving the charm and functionality of your cast iron teapot is relatively straightforward and revolves around a few key steps:

  • Clean Carefully: Ensure your cast iron teapot is cleaned properly after each use. Refrain from using soaps or detergents; never put it in a dishwasher. Warm water and a soft cloth are all you need.
  • Dry Thoroughly: Dry your cast iron teapot inside and out while it’s still warm, then allow it to air dry completely. This step is crucial in preventing rust.
  • Avoid Rapid Temperature Changes: A sudden change can harm your cast iron teapot. Always allow it to cool down naturally before cleaning.
  • Store Properly: When not in use, store your cast iron teapot in a dry place to prevent moisture accumulation.

Following these simple steps can go a long way in ensuring your cast iron teapot stays beautiful and functional for many tea-drinking years!


I’ve seen that these teapots are visually appealing and functional, providing an excellent tea brewing experience through their heat retention and flavor enhancement. 

The careful maintenance of these teapots also plays a significant part in their longevity, with the need for careful cleaning, drying, and storage.

So brew your favorite tea in a cast iron teapot and indulge in the rich experience it provides.
