coffee steam?

Coffee and the hiss of Kingman's gas stove fill the air.

When we talk about something in the air. We usually refer to something untouchable, such as steam, air, gas, sound, etc. Yet in this sentense the author use "coffee" as the Subject, in parallel to "hiss" (which is the sound of the gas stove), I am curious about this. Do you often describe things like that? If coffee can fill the air, what else can fill the air, too? A cup of tea? Wine? Liquid volatile? For I think the author refer to the steam, doesn't he?
