How to stabilize espresso extraction in humid climates? Key details and parameter adjustments for making espresso on rainy days

On days of continuous drizzle and soaring air humidity, the biggest challenge a barista faces is often not technique, but the stability of espresso. A humid environment can cause coffee beans to absorb moisture and lose flavor, and the pressure of the espresso machine may also be weakened, making extraction extremely unstable. This article starts from three angles—reducing bean moisture exposure, adjusting grind and dose, and increasing the frequency of parameter calibration—to sort out the operational details to pay attention to when making espresso on rainy days, helping you maintain consistency and flavor in your output even as humidity changes.

Why does espresso require regular grind adjustment? An analysis of the key parameters for stable output in coffee shops

Espresso extraction is fundamentally different from pour-over or French press. It relies on an extremely fine grind and 9 bar of high pressure to concentrate flavor compounds in a short amount of time—highly efficient, but also extremely sensitive. The degassing state of the coffee beans, batch-to-batch differences, roast level, and even changes in the weather can all cause extraction results to deviate from expectations. For this reason, many coffee shops regularly calibrate their espresso flavor to ensure consistent output. Drawing on Front Street's hands-on experience, this article explains the necessity of dialing in the grind, the factors that affect extraction, and how to decide whether to adjust parameters based on extraction time and taste evaluation.

Chayan Yuese Pilots Fully Automated Milk Tea Robot: Cup Output Efficiency and Consumer Experience Spark Heated Discussion

During the National Day holiday, the fully automated milk tea robots that appeared in some Changsha Chayan Yuese stores became a focal point for tourists. Customers noticed that staff only needed to place a labeled cup in the designated position, and the robotic arm could complete most of the preparation process, with only the cream top needing to be added before handover at pickup. This experiment sparked polarized discussion online: supporters believe standardized operations help ensure consistent output and reduce the burden on employees; opponents point out that during peak customer flow, the robot's cup output speed is actually slower than manual work, resulting in longer waits, and equipment cleaning and customization needs still depend on staff handling. Whether automated tea-making can truly integrate into the freshly made tea beverage scenario has become a new topic of discussion in the industry. [more…]
