As the 2024 WBrC World Brewers Cup came to a close, curiosity was once again piqued about what judges feel inwardly when tasting coffee. A team from Italy's National Research Council has designed a tasting helmet that, through wearable sensors such as electrocardiogram, galvanic skin response, and electroencephalogram, transforms abstract emotions like pleasure and disgust during coffee tasting into biomedical data. This technology is expected to assist the SCA coffee value assessment system, reduce subjective bias, and open up new perspectives for coffee sensory analysis. At present, the helmet still needs refinement, and there are plans to work with professional tasters to advance its practical application. [more…]

Besides refreshing the mind and waking you up, coffee can also promote intestinal peristalsis, which unexpectedly makes the restroom experience an important standard for judging whether a coffee shop is comfortable. Recently, a netizen from Shandong posted on social media, reviewing some of the coffee shops they had visited from the perspective of the restroom, with a unique angle and rich details. Cleanliness and hygiene, along with smooth flushing, are the basics, while spaciousness and ventilation, pleasant aromas, and the provision of disposable toilet seat covers, wet wipes, sanitary pads, and hand cream become bonus points. A layout with dry-wet separation and a reasonable flow also greatly increases favorability. At the same time, many coffee shops cannot provide restrooms due to space or plumbing limitations, or they impose restrictions on customers using the toilet. Those shops with complete facilities not only meet physiological needs, but also win repeat customers and reputation through detailed service. Front Street Coffee reminds us that paying attention to these often overlooked experiences may bring coffee shops an unexpected win-win effect. [more…]

The Spring Festival is traditionally a time for family reunions, but for frontline employees at Luckin Coffee, this year's triple-pay shifts have brought unprecedented challenges. The Guangzhou branch recently issued a notice requiring stores with fewer than 200 items to have only one person on duty all day during the Spring Festival, from opening early to closing, all completed by the same person. This means that employees on duty must single-handedly handle multiple tasks such as production, packaging, cleaning, and dealing with sudden order surges. Timely output rates, physiological needs, and unexpected order surges have become the three major problems weighing on their shoulders. What worries employees even more is that if they need to temporarily close the store to use the restroom, they must apply to the district manager in advance and submit a screenshot of the item count. This high-intensity labor efficiency management has sparked widespread discussion, with some employees bluntly saying it is "harsher than the King of Hell." This article will delve into the details behind this scheduling adjustment and the voices of the employees. [more…]

Many people assume that hot coffee is more invigorating than iced coffee, but this is not actually the case. The amount of caffeine depends mainly on the variety of coffee beans used and the amount of caffeine released during extraction, with little relation to whether the drink is hot or cold. If you want to get a large amount of caffeine quickly, cold brew, pour-over drip, or Americano are all viable options. In addition, iced Americano has become the first choice for many people to replenish caffeine because it is affordable and served quickly. As for adding milk to an Americano, although it makes the taste smoother, it is not the same thing as a latte. Using its own house blend as an example, Front Street Coffee shared suggestions for the ratio of milk added to an Americano. Finally, it will also explain the physiological mechanism by which caffeine boosts alertness, as well as the recommended daily intake, to help coffee lovers enjoy coffee in a more rational way.
