Is there a general consensus on what some of the best mugs out there are in terms of keeping (drip/pour-over) coffee warm, style, and flavor? Ceramic? Double-walled glass?

Ceramic is more porous than glass, so a ceramic mug insulates better than regular glass and thus keep the coffee hotter, but double-walled glass insulates even better than ceramic.

A porous mug might exchange molecules from one cup to the next. (Is there experimental data on that?)

From experience, glass or ceramic is usually better, but eitherway whatever kind of cup you use, make sure to warm it before pouring your coffee in it.
