How to Use a Cast Iron Teapot

Traditional Japanese cast iron teapots are a fantastic decorative piece for enhancing any tea service. To make the most of this unique drink service, follow our guide to learn how to use a cast iron teapot for loose leaf tea.

If you are already familiar with brewing tea in a ceramic teapot, then you will be familiar with this process.

Most cast iron teapots produced for the Western market have an enamel coating on the inside. This replicates the effect of ceramic teapots, making the brewing process the same.

Our Japanese teapots come with a removable infuser that sits inside the top of the pot. This means you won’t have any leaves in your tea cup when you serve. If you enjoy the tradition of tea leaves in your cup then the infuser can be removed for brewing.

How to Brew Loose Leaf Tea in a Cast Iron Teapot

  1. Warm the cast iron teapot with warm water. This reduces the chance of thermal shock to the enamel surface.
  2. Place your loose leaf tea in the infuser – measure around 1 teaspoon per 200ml of water
  3. Boil water in a kettle, add the hot water to the teapot ensuring to cover the loose leaf tea in the infuser, and put on the lid
  4. Steep for a few minutes – this will vary depending on the variety of tea, and your own preferences of strength – see our Tea Brewing Time Table below
  5. Remove the infuser

Cast Iron Teapot Warmers

If you don’t intend to serve your tea immediately, use a teapot warmer. A teapot warmer is a form of raised housing for a tealight candle. The gentle heat of the tealight helps to maintain the warmth of the tea.

Tea Brewing Time Table

Overbrewing loose leaf tea can result in releasing more tannins, giving a bitter taste. Use our beginners guide to brewing times to get you started. Depending on your preferences, you can adjust these times to suit you.

More time = more bitter

Less time = more sweet

Tea Type Brew Time
Black Tea 3 to 5 minutes
Green / White Tea 2 to 3 minutes
Oolong Tea 3 to 5 minutes
Herbal Tea 4 to 6 minutes


  • If making green tea or white tea – stop the kettle from reaching boiling point. Boiling water can cook these delicate teas and ruin the antioxidants in them.
  • The teapot handle is also made from cast iron, so will conduct heat. Make sure to use a protective cloth when gripping the handle to serve.
  • Brew time will vary depending on the size of tea leaf – finer, broken leaves will brew faster than whole leaves.
