Either that or stainless steel makes it worse.
my secret is that I skip micro plastics and go straight for the macro plastics
a diner style ceramic mug is top. Those warm curves make the coffee better
diner style
Makes me wonder what on earth you use at home
I have diner style mugs. It just refers to the shape and style of the mug. Top tier for some pour over straight black imo
Ceramic or nah, for me
You know the little oily colorful sheen on the top of a cup of coffee?
At one point just at random I made a pot of coffee from a jug of distilled water I had, instead of the filtered tap water.
It had no little colorful sheen.
I have no idea if it’s a big deal or not, but it made me legitimately concerned.
I thought the sheen was from oils naturally present in the beans.
Former barista here! This is what that is. Different machines using different roasts, water, settings, etc. will extract differently, resulting in different oil amounts.
That was my understanding, as well. I can only report to you what I observed.
Maybe something present in the tapwater allows more oil to be drawn out?
