What should you aim to monitor during the espresso brewing process?

Monitoring espresso volume and extraction during the brewing process is crucial for achieving a consistent and high-quality coffee. The espresso volume indicates the amount of liquid produced, which should align with the desired serving size. This ensures that the drink is properly portioned, providing the right experience for the customer.

Extraction refers to the process of dissolving flavors and compounds from the coffee grounds into the water. Proper extraction is critical; if the espresso is under-extracted, it can taste sour and weak, whereas over-extraction can lead to bitter flavors. By focusing on these two factors, a barista can adjust variables such as grind size, water temperature, and brew time to enhance the overall quality of the espresso.

In contrast, while customer satisfaction is undeniably important in the service industry, it is not a direct measurement or monitoring factor during the brewing process itself. Brewing temperature is a significant element of espresso preparation, yet focusing exclusively on this aspect does not encompass the broader picture required for quality brewing. Cleaning frequency, while important for maintenance and hygiene, does not directly pertain to monitoring the actual brewing process of the espresso.
