    I think it's ok as long as you boil it first.

    No you should boil water once if making tea. If you don't use it, draw a fresh kettle and boil this new water.

    Can I ask why? (you shouldn't re-boil water?)

    Water's water, the structure of it doesn't change nor is anything added/removed when it's re-boiled?

    That is true if you used pure distilled water, but you're using tap or bottled water which contains loads of other stuff as well. Re-boiling removes more of the gases in the tap water, including oxygen, which you want for tea. That's not a big problem apart from taste, the bigger concern is that re-boiling increases the concentration of nitrates, fluoride and arsenic, which you really don't want to happen.

    For adults it's never really an issue unless you're a complete snob.

    For babies you shouldn't re boil water as it will concentrate the minerals etc... in the water.

    Eh? No need to be offensive about it, its only tea we talking about here!? If you disagree put it on a civil manner like @Synesthesia did above.

    Reboiling deoxygenates the water, affecting the brewing process and resulting in an inferior cup of tea.
    It matters if you like tea and want to make it properly. Not snobbery just interest.

    sorry perhaps should have put tea connoisseur meaning someone who uses proper tea rather than the dust you get in a bag.

    I admitted I was wrong and said Id start taking the tea bags out without squeezing them. Which I do and is a lot better !!

    He did do that very well.
    Reboiling deoxygenates the water,
    Yes and no. The amount of gas water can hold is a function of temperature. As you boil water, the dissolved gasses will 'boil off'. After that, as the water cools, oxygen will again start to dissolve into the water via the surface. If dissolved oxygen is important to tea making, then re-boiling might make very little difference to the Oxygen.
    affecting the brewing process and resulting in an inferior cup of tea.

    "Like" is entirely personal. If you like it, great. "Properly" implies that there is some universally accepted definition of _The_ drink of tea, or perhaps at least that good data is available - maybe double blind trials that says people can pick a signal out from the noise, and demonstrate that oxygen makes a difference to 'like'.

    Learn something new every day My favoured tea is the dust in bag type so it probably wouldn't make much difference to me. I may well try it though, just out of idle interest. Come to think of it I had heard about not re-boiling water for children when bringing mine up.

    It often surprises people how much of a difference it makes.

    Yes good point. This is of course correct. My old Head used to wring the teabag to within an inch of its life. Tasted terrible to me but he seemed to like it.

    I can't fully substantiate this but I believe that the 'recommended' tea making process is a refinement over the number of years tea has been drunk to produce a drink that is most appealing to the majority of people. Believe it or not, making the 'perfect' brew has been the subject of more than one university study.

    I can understand that. I can't make coffee to save my life. The term 'black sludge' has been used on many occasion. I have been repeatedly shown by colleagues but I just can't do it, I think its because I have never drank it.
    People come to me for tea but avoid my coffee like the plague

    I've always thought the best thing you can do for a cup of tea is chuck it out and put something with taste in the cup, something like coffee. Still each to their own

    There are no variables in making a cup of tea if you follow ISO 3103.

    I've tried to find something on re-boiling that makes sense - and largely failed. The "concentrates harmful chemicals" doesn't really do it for me. Those chemicals are in the water and the amount of water you drive off as steam is fairly minimal, especially with today's automatic kettles, so the amount you are concentrating is tiny and it would take a huge number of cycles to make much difference chemically. If the chemicals were particularly harmful then just drinking another cup of tea would give you the elevated dose that re-boiling 50-100 (probably lot's more) times time would.
