— a "lungo" is a type of espresso (see the relevant paragraph), that is characterized by a larger volume of approximately 60 mL and a longer extraction time. The extended brewing process allows for a more intense flavor compared to a classic espresso, and it also contains a higher caffeine content both per serving and per unit volume. Some people refer to lungo as the "Italian version of an Americano", because it bridges the gap between espresso and Americano in terms of taste and strength.
