"This is a problem I can't believe no one has covered. This idea seems great, but here is the problem, something I didn't think about happening. The constant heat that comes from the tea light candle will continue to 'cook' the elements of the tea, altering it's fresh made flavors. The tea will become darker, and the fine characteristics of the tea begins to get covered up in a short time over the candle. This is coming from someone with not the greatest nose, but you can easily see it darkens cup after cup, and I can taste it changing. So if I notice it, others must be able to. I did Ali Shan, and Silver Needle White teas. It's as if the constant heat gives the tea a plain 'Lipton' tea flavor over time, that begins to cover up certain characteristics. The Ali Shan suffering this outcome far worse than my white tea. Probably not the best thing to steep Ali Shan in, since it is hard for the leaves to open, however even when done, after a half an hour over a candle, the tea is not the same as fresh. The idea behind this is to be able to drink warm tea over a long period. I will not, at the expense of what the tea is supposed to taste like. Sorry to burst someone's bubble, but if it was a light ambient heat over the entire kettle, it probably would not suffer this outcome. I am sticking with single cup brewing, as the flavor is always consistent, with a little more work. Perhaps this will not bother some people, but it certainly does me."
