title_body: Doppio vs. Short Black: What's The Difference?
upvoted_answer: As far as I know, a short black is a single espresso, as in it's literally just another word for a single espresso. A short black is a single 30ml shot, and a doppio is two, 60ml. Nothing added to either, and the vessel you're serving it in varies by where you are, and doesn't change the name in any case :-)
