   Can someone explain the science to me of why if you make pour over coffee with water from a kettle vs water from a microwave it tastes so different? I’m always on team kettle but I want to know why I genuinely feel like it tastes so different. Microwaved water coffee tastes muddy and flat to me

     @skinnylatte my first question would be "does the effect survive a double-blind trial?" :blobfoxlaughsweat:

     but otherwise the mineral content others mention could be responsible? I'm very skeptical of the proposed aeration mechanism since it's being poured over anyway.

     I used to microwave water for french press coffee before I got a kettle and I've never noticed a difference, so that's part of what informs my intuition for a psychological effect here

     @SnoopJ I don’t feel it as strongly with a French press compared to pour over and Chinese and Japanese teas

     But I’m also used to kettle only (never heard of microwaving water until I came to Murica hahah)

     @skinnylatte this article suggests it is because the kettle heats the water evenly while the microwave does not
