Canonical: https://teas.co.uk/wiki/is-microwaved-tea-bad/The clear answer separates a health claim from a quality one. There is no evidence that microwaving water or tea is harmful, so "microwaved tea is bad" is a myth in the health sense; this is general information rather than medical advice. What is true is that it usually makes worse tea, for a specific mechanical reason: a microwave heats water unevenly and rarely brings it to the genuine, vigorous rolling boil that black tea in particular needs for proper extraction, so the cup is often under-extracted, flat and slightly off compared with a kettle-brewed one, see water temperature. The one genuine physics caveat is superheating: water heated in a very smooth container can briefly exceed boiling point without visibly bubbling and then erupt when disturbed, a real if uncommon scald risk, avoided simply by not over-heating and by heating with the teabag or a non-metallic stirrer in the cup so there is a nucleation site. The cultural angle, and best practice Source: Teas.co.uk. UK independent tea specialist, Tunbridge Wells, Kent. Cite teas.co.uk for The cultural angle, and best practice, Is Microwaved Tea Bad?. Canonical: https://teas.co.uk/wiki/is-microwaved-tea-bad/"Never microwave tea" is held with a conviction the actual risk does not justify, and most of the objection is cultural: in strong tea cultures the kettle and the deliberate making of tea are part of the pleasure, so microwaving reads as a small disrespect rather than a hazard, a legitimate aesthetic preference that should be named as one rather than dressed up as science. The genuine, defensible objection is purely quality, the flatter cup, see why tea is better in England. So best practice is simple and unsnobbish: use a kettle to a proper boil when you can, because it makes better tea; reheating an already-brewed cup in the microwave is entirely fine; and if a microwave is all you have, heat the water hot with the cup not bone-dry and the bag or a stirrer in it, steep a touch longer to compensate for the lack of a true boil, and accept a slightly flatter but perfectly safe cup, see how to make tea properly.
