Guangzhou's "hui nan tian" (return of the southern damp) has arrived, with walls sweating, floors never drying, and coffee beans facing a moisture crisis. A surge in humidity directly affects the stability of espresso extraction: beans in the hopper absorb moisture and clump together, water vapor interference during grinding intensifies, and as air pressure drops, the espresso machine's extraction pressure slightly decreases, ultimately leading to weaker flavor and longer shot times. How should baristas respond to such harsh weather? This article approaches the problem from three angles—reducing moisture absorption, solving clumping, and adjusting parameters—and combines Front Street Coffee's hands-on experience to offer concrete, actionable solutions that help you pull a stable, delicious espresso even in the humid season.

This article will break down these factors affecting espresso extraction one by one, and explain the parameters and logic behind making a standard iced Americano, helping coffee lovers understand the espresso system behind a delicious cup.

Starting from a real conversation at a Front Street location, this article breaks down the logic behind americano coffee "losing its flavor."

By understanding these variables, coffee enthusiasts can gain a more comprehensive understanding of the espresso coffee system and discover more possibilities in a cup of iced americano through products such as Front Street's Warm Sun Blend.

Although the online trick of adding water to eliminate static works, it carries hidden risks. This article will break down the causes and solutions one by one, making the grinding process cleaner and smoother. [more…]

In recent years, more and more people have chosen to buy whole coffee beans and make freshly ground coffee at home, and the coffee market has continued to expand. However, a recent recall notice issued by Costco in Taiwan drew widespread attention—some organic Sumatra coffee beans were urgently recalled because the packaging seals were incomplete. Some consumers reported finding large holes in the bags or incomplete seals during inspection. It is worth pondering that this problem may not be a simple sealing defect, but may be related to the design of the one-way degassing valve on the bag. After roasting, coffee beans release a large amount of carbon dioxide. If the degassing valve does not function properly, the pressure inside the bag becomes too high and pushes the seal open. In that case, will the coffee beans spoil? And how should beans be properly stored when stockpiling them in daily life? This article will answer these questions one by one. [more…]

When grinding coffee beans, have you ever encountered coffee grounds splattering everywhere or sticking to the dosing cup or the exit chute? There are usually two reasons behind this: the oils seeping out of dark-roasted beans, and static electricity in a dry environment. Dark-roasted beans have a loose structure, and as carbon dioxide is released, oils seep out along with it, making the ground particles prone to clinging to the cup walls; static electricity, meanwhile, causes fine particles to stick to the grinder's exit chute, reducing the actual amount of grounds you get. Some newer electric grinders come with anti-static plates, but many small electric grinders and hand grinders don't have this design. The Little Fuji grinder that Front Street Coffee once used had long-standing problems with flying grounds and retained grounds, and the bottom of hand grinder burrs often end up covered in coffee grounds. In addition to analyzing the causes, this article will also share a simple anti-static method of stirring coffee beans with a wet spoon, and remind you of the risks and precautions involved, helping you reduce waste and improve your grinding experience.
