Every Macbook or Macbook Pro I've had since ~2012 has had this issue. It doesn't present primarily as a "metallic taste", though. It's more of a barely perceptible tingle when my fingers touch the metal casing. It's especially noticeable when it's cold and when the ambient air is dry.
It only happens when I'm using the power brick with the two-prong "duckbill" plug; it doesn't happen with the old three-prong extension cable attached. From that, I assume it's a grounding issue.

It's well documented and as you noticed, only happens when 2 things are true: * The battery is charging; and * The charger is ungrounded If you read through the thread, OP says: > only have tried battery so far. https://forums.macrumors.com/threads/weird-taste-in-mouth-when-using-midnight-13-m3-air.2422177/?post=33017781#post-33017781 https://forums.macrumors.com/threads/weird-taste-in-mouth-wh...
