I think without sugar you'll be ok....
I know the story of a museum trolley, originally built for Naragansett, and spent most of its life in Rio DeJanerio .... when they closed down the trolley system and it came back to the US to the museum, it was shipped on a coffee barge; the (wooden) body on the deck, and the trucks down in the hold, which was then filled with coffee beans.
For several years when you made the transition on the controler from Series to Parallel, the whole car filled up with the smell of roasted coffee....
