Many coffee enthusiasts are puzzled by the practice of coffee shops adjusting their espresso every day, believing that as long as the dose, water temperature, yield, and grind size stay consistent, the taste should remain stable. However, the pressurized extraction method of espresso is extremely sensitive—the degassing state of the coffee beans, the weather humidity, and the wear on the grinder burrs can all cause flavor deviations. This article analyzes in detail how carbon dioxide affects the crema and extraction, why it is harder to pull a good-tasting espresso on rainy days, and the reasons behind changes in grind size, while also sharing Front Street Coffee's professional interpretation of the necessity of daily espresso calibration.

Spring has arrived, and Guangdong is experiencing continuous rainy weather. For baristas who need to get up early every day to dial in espresso, this period is undoubtedly a challenge. Many coffee enthusiasts have noticed that with the same beans and the same parameters, as soon as a rainy day comes, the espresso machine seems to throw a tantrum, and the extraction results are always less than satisfactory. What exactly causes espresso to be so difficult to dial in on rainy days? This article will analyze in depth from multiple angles such as humidity, temperature, and bean condition, helping you understand the real reasons why espresso machine extraction is unstable in wet weather, and offering practical approaches to deal with it.

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.

Under rainy weather, espresso extraction often becomes especially tricky, and even experienced baristas may need to adjust repeatedly before getting a satisfactory cup. The root of the problem is not simply under-extraction or over-extraction, but uneven extraction caused by the combined effects of high humidity and low air pressure. Starting from Front Street's hands-on experience, this article first analyzes the two major reasons why espresso is difficult to dial in on rainy days—a surge in environmental humidity causes coffee grounds to absorb moisture and clump, while lower air pressure weakens extraction efficiency—and then provides specific response strategies, including dehumidification and moisture prevention, sealed storage, and compensating for the amount of dissolved flavor substances by extending extraction time or making the grind finer. The article also includes a parameter comparison of Front Street's classic blend under normal weather and rainy days for readers to refer to when adjusting. [more…]

Honestly, Front Street Coffee believes that in a barista's daily work, there is nothing more painful than the morning ritual—dialing in espresso. If there's anything more painful than that, it must be dialing in espresso on a rainy day. Because if you're not careful, you'll end up full of espresso, drinking it until you're sick of it. Some friends find this very hard to understand; they think [more…]

The same shop, the same beans, yet the americano can often come out tasting like two completely different cups—Front Street Coffee's store received exactly this kind of feedback from customers this week. The article starts with the minimalist essence of the americano: "espresso diluted with water." Since the recipe is fixed and water has no flavor of its own, any variation can only come from the espresso itself. It then breaks down, one by one, four variables that are often overlooked: the resting rhythm and ongoing degassing of the coffee beans, the interference of rainy, high-humidity weather with grinding and pressurization, particle size drift caused by hopper pressure, and the heat effects of a grinder running nonstop. It also includes the actual brewing parameters and bean-resting experience for Front Street Coffee's Warm Sun beans, helping you understand the story behind the flavor ups and downs of a single cup of iced americano.

The Huila region of Colombia lies among the mountains of the south, where high altitude, volcanic ash soil, and a climate with distinct wet and dry seasons together shape the clean, balanced, and mellow character of the local washed coffee. For those just getting into pour-over coffee, Huila washed beans are often the most friendly entry-level choice—they are not as bright and flamboyant in acidity as Yirgacheffe, nor as rich and heavy as Mandheling, but instead present the sweet aromas of nuts, chocolate, and caramel in a gentle manner. Front Street Coffee lists it as its top recommended everyday bean, using a medium-dark roast and pairing it with a KONO dripper and medium water temperature for extraction, allowing the bean's complex fruity juice sensation and roasted aroma to be fully released. This article will completely break down the flavor sources of Huila washed coffee, from the growing region's environment, variety composition, and picking and processing to the brewing parameters.
