Query: It's PLASTIC.

Pretty sure I can tell plastic from stainless steel and this carafe is plastic. That said, with the glass interior it keeps the morning coffee hot until mid-afternoon, it doesn't look bad aesthetically, and the imitation leather also pads the bottom of the carafe. So if you don't mind a plastic and faux leather carafe this may be the one for you.
