Can I make tea with carbonated water?

Question

Whilst staying with a friend who lives somewhere with very hard water, we got used to making tea with bottled, still, water as the tap water was too hard to make a good cuppa.

One day, we ran out of still water, but had some bottles of carbonated water.

Having previously ruined a kettle when I was a kid with the 'genius' idea of boiling milk in there I was reluctant to risk ruining his kettle to see if you could make tea using the carbonated water. Once bitten, twice shy as they say.

So would this have worked out ok? ie would anything have been damaged? would boiling water have spurted out of the kettle?

And could I have made a good cuppa from carbonated water, or would it have worked but tasted terrible (no dissolved oxygen?)?

Answer

In the interests of science I gave this a try. Used a can of carbonated water, boiled in my kettle. There was no boiling water explosion, although I more than half expected one. It seemed to maybe boil a little faster, but that's more likely due to the fact that it's less liquid than I usually heat.

Being a tea fanatic I have a lot of flavored teas but I opted for PG Tips, figuring I would taste any difference a little more easily. I caught very little flavor difference from usual, maybe a little stronger but that could be chalked up to any number of things besides using carbonated water.

So yeah, I think carbonated water would probably work in a pinch. Probably don't put too much of it in the kettle, though. (A small part of me still suspects that had it been full it would have shot boiling water everywhere).
