I haven't heard that before but it would explain why I prefer coffee with the milk poured in before the water. I can always tell if it's done the other way around...
Whilst I do not know, what I do know is the instructions that came with the coffee filter thingy I bought a while back said it should be using hot not boiling water, so maybe there is something in it. In fact on the Internet (if one can believe what one reads there) IO recall one site suggesting tea should not normally use boiling either as it is only the black variety (which I guess is the one most used) that can cope with it.
But ... I reckon if you can't tell the difference with your instant brand then you need not lose much sleep over what the water temperature is.
very true - MIF. Tea on the other hand requires to water to be boiled and poured into to the cup straightaway.
This is why you shouldn't put milk in with the tea-bag before the water; it will cool the water quicker than you want. The Enzymic activity required when brewing tea will only happen properly in the first few minute or so of boiling point.
I think you are right, but an reall no-no is to pour boiling water into a cafetiere. As this can scald the ground beans, always leave 10 seconds after the kettle is boiled before adding the hot water.
How many people put a tea bag into a cup, splash on some cold milk and then add boiling water ?...Drives me mad !
