What are the three styles of espresso shots?

The three styles of espresso shots are Ristretto, Normale, and Lungo, each differing based on the amount of water used and the extraction time, which ultimately affects the flavor profile and strength of the espresso.

Ristretto is a shorter extraction, using less water, which results in a more concentrated and intense shot of espresso with a sweeter flavor and less bitterness. Normale, or a standard espresso shot, balances water and coffee to produce a well-rounded flavor profile, typical of what most people envision when they think of espresso. Lungo, on the other hand, involves a longer extraction with more water, resulting in a larger volume of coffee that tends to be milder and sometimes more bitter due to the extended contact time with the coffee grounds.

The other options encompass different categories or types of coffee drinks rather than styles of espresso shots. For instance, the second choice lists different coffee drinks made with espresso, while the third mentions sizes often used in coffee shops rather than styles of espresso itself. The fourth option includes various brewing methods rather than focusing solely on espresso shots, thereby clearly differentiating it from the correct answer.
