Do you know if that metallic taste is considered (in-)healthy? I have no clue and actually like that taste and must admit that in the steel for everything department I’m following the trends as well (steel for cooking - no PFAS; steel for drink containers - no plastics).

Stainless steel has nickel and chromium in it which can leach out, but I don't think incredibly tiny amounts have been shown to be bad.

It's harmless. The sensation is electrolytic in origin rather than caused by taste receptor activation; it's like when you put a 9 V battery to your tongue except much less potential and therefore weaker feeling.
