Stainless steel makes everything worse. It’s the worst material for a beverage vessel

I drink my coffee from a ceramic mug and it’s pretty good

Might sound odd, but give it a try: put a pinch of salt in your coffee. Just a very small one. Helps even with the most terrible coffees.

do you just not have ceramic or glass cups

Nah, coffee in ceramic cups also tastes awesome! You should go to a speciality coffee place and let them recommend something based on what you like :) Don’t go to Starbucks or the like tho
