Which shot has the highest amount of water in its preparation?

The shot that has the highest amount of water in its preparation is indeed the Lungo. A Lungo is an espresso shot that is pulled with more water than a standard shot, typically by increasing the extraction time or the grind size. This results in a longer brew time and yields a shot that is not only larger in volume but also has a different flavor profile.

The increased water ratio in a Lungo dilutes the coffee more than other espresso shots, leading to a milder taste compared to a Normale, which is the standard espresso shot with a balanced water-to-coffee ratio. On the other hand, a Ristretto is made with less water, resulting in a shorter extraction and a more concentrated flavor.

Thus, among the choices provided, the Lungo is correctly identified as the shot with the highest amount of water.
