Many tea lovers use cast iron teapots to brew Japanese green teas — like Sencha or Gyokuro. But honestly, they’re as versatile as they are beautiful. This guide covers cast iron teapots, the benefits of using one, and how to choose the best one.
Yes, cast iron teapots are great for brewing tea. They’re especially known for their superior heat retention. This means your tea stays hotter, for longer, with every brew.
Cast iron teapots are traditional and unique at the same time. They were originally designed to brew tea over open fires. Now, many cast iron teapots have an enamel coating inside, which means they can’t be heated over direct heat.
Although you can brew any kind of tea in a cast iron teapot, many tea lovers choose green or oolong.
First, pre-heat the teapot by filling it with warm water. Let it warm up as you boil water in a separate kettle on the stove.
Once the water boils, empty the teapot. Place an infuser inside the cast iron teapot, and fill it with tea leaves. Then, carefully pour the boiling water from the kettle over the leaves and into the cast iron teapot.
Some cast iron teapots can be heated directly on the stove. However, others are coated with an enamel coating.
If your cast iron teapot has an internal coating, it’s best to avoid placing it directly on a stovetop. Instead, preheat the teapot with warm water as you boil water in a separate kettle. Pour out the water in the teapot before filling with boiling water from the kettle.
Yes, cast iron teapots can rust. Rust usually builds up when standing water sits inside the teapot when not in use. To avoid rust, thoroughly try your cast iron teapot after each use. Never let any tea or water sit in the teapot for prolonged periods of time.
If you use your cast iron teapot as directed, it’s perfectly safe. As well, make sure to follow all cleaning and storage protocols to prevent rust build-up.
Never use dish soap, detergent, oil, or salt on your cast iron teapot. As well, always wash your teapot by hand — never in the dishwasher.
Instead, let your cast iron teapot cool completely before cleaning. Rinse the inside and outside with warm water, then dry with a clean cloth. Allow the teapot to completely dry by placing it upsidedown.
