cast iron vs stainless steel

by orguz » Oct 9th, '08, 21:01

want to add my 2 cents worth, recently acquired an electric kettle made of stainless steel, I noticed that my teas don't taste as good when the water came from my cast iron kettle.

The difference is noticeable the C.I gives the tea a fuller open taste whereas the steel kettle makes my tea flat and boring.

Has anyone paid attention to this ?

If you like your new kettle, maybe you should consider using bamboo charcoal to compensate.

Your CI kettle, I am assuming it is a kettle, another words not lined with enamel. Just cast iron?

If so, that enhances my desire to own one some day soon.
blah blah blah SENCHA blah blah blah!!!

I have noticed that as well. I use my electric kettle most days, just for tastings and simplicitea, but when I am sitting down to tea I use my bakufu era cast iron. It gives the tea a mellow, yet complex, flavor that is not present otherwise. I would love to see a picture of your CI pot if you have one.

My cast iron is an unlined Tetsubin and to Victoria I did add bamboo charcoal and that didn't do it either. I admit that cast iron really makes a difference, having used the C.I for at least 1/2 year and switching to the other, one's taste buds notices the obvious change.

Orguz, what is the design on that delightful tetsubin of yours?

I think I can possibly make out rice-ears and a sparrow, but that may just be wishful thinking (since it's also one of my favourite motifs).

I have questions too! How long does it take to bring water to a boil in that tetsubin? And how much water does it hold?

It's fast when you use a conduction plate. 3 mins tops at medium setting. Tetsubins are available in various sizes. Mine is 1.5 litres, go check out Artistic Nippon. How is the overcooked tea leaf taste doing? Resolved that yet or still persisting, must be Montreal water I think. :P

Haha I have concluded that the bad tea taste is a result of ........ bad tea. Basically, the few teas it was happening with just couldn't handle the high heats and I will avoid them from now on.

I know they're available in different sizes... I was just asking so that the heating time made sense relative to how much you're heating. 3 minutes is faster than my electric kettle takes. I thought tetsubins were supposed to take forever to heat up... I guess I was wrong. Or is it just that conduction plates are amazing?

conduction is fast, than again tetsubins are not that thick walled, so the heating time is reduced also. I recommend using one if you're anal about taste like me.

I have tried the lined testbutin but the taste was not as good as clay pots....I might have to look into unlined testbutin....

Artistic Nippon is quite expensive, buyer beware.

3 minutes :shock:?
It takes 15-30 minutes to bring my tetsubin to boil on 'normal' stove. Do you mean induction plate?

Yes I meant using induction plate. 15 - 30 minutes is awfully long, too long buy an induction plate online I think you can get one for $50 to $60 or less.

When I read this tread (and something similar on the teamasters blog) I went to my parents place to borrow this old tetsubin:
Image
My dad bought this more than thirty years ago, and it's a bit rusty. It took a little less than ten minutes to bring half a litre of water to the boil. Maybe it would take less if the bottom were more flat? This tetsubin is only in contact with the hotplate along the border of its bottom.
Image

My first impression was that the tea I made from this tasted a lot more of fresh water than the tea I make from my eletric kettle! In fact, it reminded me of water from wells.
But I am not entirely sure how much was up to my expectations, or if I was influenced by the nice looks, smells and sounds from the kettle...
I certainly will have to make some experiments (and blind tests) with this!

One thing is certain anyway, there is quite a lot of iron dissolved from this tetsubin - when I poured up a glass of the boiled water it was light yellow and clearly had an iron taste. Maybe this will diminish if I use it for some time?
