Heating method of kettle affects the taste of tea
- [2016.05.18] Posted By Akira Hojo
Have you ever thought that the taste of water varies a lot depending on the type of heating device we use for boiling water? Regardless of using a cast iron kettle (tetsubin) or normal stainless steel kettle to boil water, the taste is not the same if we change the heating method. I think only few people know this fact since we hardly have a chance to compare the taste of water boiled with different heating devices.
IH reduces body
If the Induction Heater is used, the water from cast iron kettle or stainless steel kettle has very light body, although it has quite strong aftertaste. The flavor of tea becomes slim and less complex. I guess it is due to an electromagnetic wave. I observe the same trend in taste if we heat water or in microwave. If you like rich and bold body in taste, and widely spreading flavor, you may want to avoid using an Induction Heater.
Please look into the heating method
Likewise, the taste of water (and subsequently the taste of tea) heated by gas stove, wood stove or electric heater is completely different, eventhough you are using the same kettle. If you are very particular about the taste, you may look into the heating method. I personally using electric heater. In term of taste, this is not the best choice. However, it gives reasonably acceptable taste. I would say it is a safe choice. I have set up an Induction Heater in my office for boiling water. Eventually I have not used it for more than 2 years, since the taste of water is not ideal.
