I personally really like my digital electric kettle, that way I can set the temperature specifically meant for various types of tea. Black tea is typically brewed the hottest (190* iirc) while green tea is lower and oolong and herbal teas are even lower than that.You do tea in a machine?......sacrilege ......always in a pot, bring the heat up slowly to just under boiling, back it off a bit and let sit heating for 30 min.....off with the heat for another 30. into the jug with the sugar in there, stir.
