In the food service industry, it is already the norm for employees to wear masks at work. However, during the hot summer days, keeping one's mouth and nose covered under a mask for long periods inevitably causes discomfort. Recently, employees at Luckin Coffee stores noticed that the new masks distributed by headquarters differ noticeably from the old version—lighter in color and thinner in material, yet breathability does not seem to have improved as expected. After wearing them for a few days, many employees developed red bumps and itching on their chins and cheeks, and some suspect this batch of "veil masks" is the culprit behind their skin breakouts. Employees also reported that the new masks have an odor, and a few sensitive individuals experienced itching in the nose after putting them on. Everyone worries that these thin masks not only have questionable protective effectiveness but may also trigger allergies due to material issues. Some employees have already said they will buy their own masks as replacements. Although requiring masks is intended for food safety reasons, the skin problems reported this time may be worth Luckin re-examining the quality of its masks. [more…]

When grinding coffee beans, static electricity often sends fine particles flying and clumping together, not only dirtying the grinder's chute but also disrupting the uniformity of water flow during extraction. To solve this problem, as early as 2005 someone proposed spraying a small amount of water onto the coffee beans, commonly known as RDT (Ross Droplet Technique). Does this method actually have a scientific basis? Will it have a negative impact on grind quality? This article starts from the mechanism by which static electricity is generated, combines it with the latest research, analyzes the actual effectiveness of the water-spraying method, and also points out the risks to watch for during operation, especially the problems that can arise when the amount of water sprayed gets out of control, such as coffee grounds becoming damp, clumping, and even burrs rusting. For friends who like making coffee at home, as well as for Front Street Coffee, which insists on professional output, understanding these details helps in using this technique more rationally.

Judging whether a cup of coffee tastes good varies from person to person, but when it comes to the defective flavors caused by extraction problems, people often reach a consensus. This article, from the perspective of Front Street, introduces the specific taste manifestations of under-extraction and over-extraction. When under-extracted, coffee presents sharp acidity, noticeable saltiness, a lacking finish, and thin flavor; over-extraction, on the other hand, allows bitterness to greatly suppress other flavors. The article also specifically reminds us not to rigidly adhere to the golden cup extraction numbers, because bean quality and processing methods can cause deviations from theory, and ultimately the real sensation on the palate should be the basis for judgment.

It is no longer news that chain coffee brands sell merchandise. Products such as cups, pins, and canvas bags can not only increase revenue but also cultivate fan loyalty. However, once merchandise has quality problems, after-sales disputes follow one after another. Recently, a netizen posted that the bottom of the inner liner of a stainless steel insulated cup they bought from Starbucks had black rust spots, and when they asked the official side for a replacement, they were refused on the grounds that it was "beyond the after-sales time limit." The post resonated with a large number of consumers. Some complained that quality control was worrying, while others believed that the way it was used might be the key. Three days after the incident gained traction, the blogger updated the progress, saying that Starbucks had agreed to replace it. Who is actually responsible in this dispute? And how should brands balance the appearance and quality of merchandise? [more…]

Making SOE with light-roasted beans is one of the more challenging aspects of espresso extraction. Drawing on the hands-on experience of Front Street Coffee, this article explains in detail how to set the extraction formula, how to adjust the grind setting according to the roast level, and provides troubleshooting approaches and adjustment plans for three common problems: sharp acidity with no lingering aftertaste, excessive bitterness from over-extraction, and thin crema. The core logic is: light-roast SOE requires higher extraction efficiency, and a brew ratio of 1:2 with a time of 30–35 seconds is a common starting point, but the final taste still depends on cupping judgment—fine-tuning the grind size and the yield are the keys that determine success or failure.

The taste of coffee does not have only three dimensions—sourness, sweetness, and bitterness. Saltiness also objectively exists in the coffee liquid, but it is usually masked by other flavors. When an obvious salty taste appears in a pour-over, espresso, or cold brew coffee, it often means that there is a problem in one of the links: bean quality, water quality, or brewing parameters. Starting from the daily communication cases of Front Street Coffee, this article sorts out the sources of saltiness in coffee, analyzes the two typical situations of under-extraction and excessively high concentration, and gives judgment methods and directions for parameter adjustment. At the same time, in response to the problem that cold brew coffee tastes too weak, the article also provides bean selection suggestions to help coffee lovers make a cup of cold brew with clear flavor and balanced acidity and sweetness in summer.
