title_body: Can I have this type of coffee?
upvoted_answer: The beverage you make by diluting vending machine "espresso" with hot water is called "poor imitation of Americano". It is hard to say how much caffeine it contains because it's not clear what this particular vending machine is filled with. It would also be wrong to speculate on its health effects without this knowledge and without knowing whether in general coffee is good for you. Unfortunately, there're many people around who drink such poor substitute of a good espresso made by a professional barista with a real espresso machine from good and fresh roasted beans.
