Which Tea Kettle Should I Use to Brew Japanese Green Tea?

As my followers know, Japanese green tea is a major part of my life.  Green tea also has become a very important aspect of many cultures.  Each culture has created its own traditions of brewing and serving green tea.  

This tradition includes the use of tea ware or teapots for brewing Japanese green tea.  Traditional Japanese teapots are called “kyusu”.  A kyusu is designed specifically for brewing Japanese green teas.  

When we talk about green tea quality and taste, there is great difference between loose leaf green tea and teabags, in general.  And, although brewing loose leaf Japanese green tea (sencha) may be a bit more detailed or require more steps, the result is well worth the effort.

So, we’re focusing today on the best tea ware for brewing loose leaf Japanese green tea (sencha).  To know the right tea pot to use, read on for my insight.  There are a few things to consider.

The Design Should be More Function than Form

Of course, the design of your teapot should be attractive.  However, I believe the teapot should be functional.  

Is the teapot heavy?  Does it maintain the temperature of the tea?  Is it easy to clean?

You want your teapot to be easy to handle, with a sturdy lid and wide opening to a allow tea leaves and water. 

The spout should be stout and line up with the handle for easy pouring.   To avoid dribbling when pouring, the spout should be tapered, with a wide base and narrow tip.  The spout should also reach above the body of the teapot for ease of pouring.   Inside the spout should be smooth, which allows the green tea to stream smoothly.

The Materials Used in the Tea Ware is Important

The material used to make the tea ware is important. The raw material of the tea ware can affect the taste and quality of green tea.   The material also impacts a preference for appearance, weight, maintaining tea temperature, and ease of cleaning.  

Many options in the design of green tea pots exist.

The Cast Iron Tea Ware is Classic and Durable

The cast iron tea pot, oftentimes called a Japanese tetsubin is fashioned with a spout from cast iron. Originally, tetsubin was the name given to a Japanese cast iron pot to boil the water for tea directly on a heating source (such as hot coals).  However, modern designs have incorporated an enamel internal finish to allow the tea pot to be used for the green tea brewing.  Many cast iron tetsubins have an internal strainer to further allow for a convenient brewing of Japanese green tea.

The tetsubin is favored for its sturdy build, almost incapable of destruction.  The original material is perfect to retain heat for an hour or more, allowing for an extended time to enjoy your hot steeped green tea.  Clean up is simple, requiring a simple rinse in warm water and thorough drying (to avoid rusting.  A bit of iron supplement can also be obtained when steeping with the tetsubin.  

The negative aspect of the cast iron tea ware is the weight of the cast iron, which some people disfavor.   If a diffuser strain is not included, a separate strainer will be needed to separate the tea leaves.

 Clay Tea Ware Is the Most Traditional

Traditional Japanese green tea ware is found in the clay teapots.  Although many cultures rely on a clay teapot for the darker teas that are highly oxidized, the Japanese culture has long used the clay pot to brew Japanese green tea.

The clay tea ware is both classic and refined.  Depending on the type of clay used, some clay teapots – like the beloved Tokoname Yaki - can enhance the green tea flavors and aroma. 

Although the iron-rich red clay of the Tokoname Yaki will enhance each steeping with the memory of the former, most clay tea ware will not.  Regardless of your preference, the clay teapot design is very sturdy and durable over time.

Glass Tea Ware is Beautiful & Light

The beautiful glass teapots allow you to admire the beautiful green tea leaves brewing as they change the water color brightly green. 

Glass teapots disperse the infusion quickly, without affecting flavor.  This is perfect for Japanese green tea. The design is lightweight and truly indispensable when brewing and serving blossoming teas.  Clean-up is simple with the glass tea ware.

The beauty of the glass tea ware is marred only by its fragility, which is susceptible to breaking when serving and cleaning. 

Porcelain and Ceramic Tea Ware is Classic 

Porcelain pots are considered a classic tea ware with an adaptability to different types of teas.  They are best used for the lightly oxidized teas, such as green tea and white tea.

The porcelain and ceramic teapot is very versatile because it does not absorb the tea’s flavor, so it can be used for many different teas, without requiring a separate pot for each.  

You will find the porcelain or ceramic teapot has a tendency to become stained by tea residue and it doesn’t maintain heated tea very long.

Silver Tea Ware is Beautiful

Silver teapots are known to give a refreshing water quality to Japanese green tea.  Silver is fine for the soft teas, such as green tea and white teas.  They are also beautiful to look.

The negative things about silver teapots is that they are difficult to maintain, due to their propensity to tarnish and are probably the most expensive tea ware.

Stainless Steel Tea Ware is Modern & Functional 

Modern look for a traditional beverage.  Very true to the water quality in that it does not change the flavor of the green tea or absorb steeping flavors.  Another benefit is the steel’s ability to maintain heat and not allow the green tea to cool down too quickly.   It is also very easy to maintain and keep clean, especially the newer designs with non-smudge finishes.  There are many options for design and finishes.   

My Favorite Tea Ware to Brew Tasty Japanese Green Tea


The ability to brew delicious Japanese green tea quickly is such a joy.  I mean, why wait for that first delicious cup if you don’t have to.  

So today, we’re looking at the convenience of the OXO BREW Cordless Glass Electric Kettle, which I personally use daily.    It is manufactured by OXO.

One great option for making tasty Japanese green tea is by using an electric tea kettle.  There are a couple of reasons to use an electric tea kettle.

Microwave Brewing is Not Exact and It Takes More Time

Microwaving your water to brew Japanese green tea takes more time than most electric tea kettles.  This is because you must keep swirling the water as it heats to get even temperatures.  

Also, with microwave heating there is no easy way to assure that you are getting the right temperature for brewing your tea.  For example, most Japanese sencha green tea is best brewed at 175 degrees Fahrenheit (79 degrees Celsius).  Herbal teas taste best when steeped at 212 degrees Fahrenheit (100 degrees Celsius).  Oolong teas are best brewed at 185 – 205 degrees Fahrenheit (85 to 95 degrees Celsius).    (See list of proper temperature by tea type here)

I need tea fast please...

Stovetop Brewing Is Not Exact for Proper Brewing Temperatures 

Stovetop heating your water in a kettle may be a fast way to get hot water.  However, much like microwave heating, it is difficult to assure the correct temperature.

When you use the stovetop, the entire heating kettle becomes hot, including the handle.  This can lead to a burn.  The conventional kettle can also pick up flavors and aromas from previous uses, impairing the pure green tea aroma and flavor. 


What Do I Use for Boiling Hot Water?

Readers often ask me what teapot I use to brew my tasty Japanese green tea.  For those who wonder, the tea ware that I currently use is the OXO BREW Cordless Glass Electric Kettle, Stainless Steel.

Some of the main reasons I prefer this tea pot are listed below:

  1. Temperature Control – Essential to each variety of tea preparation is the water temperature.  This product temperature dial maintains the precise temperature for brewing up to 30 minutes.

  2. Quick Heating – The OXO Brew provides boiled water very quickly.

  3. Yuzamashi is EasyYuzamashi, or the process of first boiling tea water then letting it cool, is simple with this teapot.  After boiling, I can remove the kettle for a few minutes and then replace it again to check the water temperature. (Read more about yuzamashi technique here)
  4. Cordless Design is Convenient – The OXO’s cordless design provides easy maneuverability once the water temperature is reached.  The cord also stores easily when not in use.

  5. Wide Spout is Great – Many tea kettles have a narrow spout, more advantageous for pouring coffee than green tea.  The OXO spout also has a convenient spout strainer, which can be easily removed for cleaning

The only drawback I have found for this tea ware is that there is some difficulty draining out the last few drops of tasty Japanese green tea.  But, hey, if this happens, looks like it’s time to brew another pot.
