How long are espresso shots considered good for in the shot glass?

Espresso shots are typically considered good for about 30 seconds after they are extracted. This timeframe is important for maintaining the quality and flavor of the espresso. Over time, the espresso can lose its crema, which is the golden, foamy layer on top that contributes to both texture and flavor. After 30 seconds, the espresso can become flat or develop bitter flavors, diminishing the overall drinking experience.

It's crucial for baristas to serve or use the espresso quickly to enhance customer satisfaction and ensure that the beverage is at its best. This understanding of timing is vital for baristas, as it helps them deliver the high-quality coffee experience that Biggby Coffee aims to provide to its customers.
