Recently, ChaPanda once again became the focus of public opinion due to food safety issues. On the evening of October 9, the brand's official Weibo posted two statements in succession, responding to the incidents of "using expired raw materials" and "a Ningbo customer complaining about finding a spider in a drink." Regarding the spider incident, ChaPanda said the source of the spider in the video was unknown and difficult to verify, and explained that the 600 yuan compensation was a response made by store employees to settle the matter, but this response did not calm netizens' doubts. A week earlier, ChaPanda had just apologized after a blogger's undercover investigation exposed the use of expired materials with replaced labels. In fact, since the beginning of this year, ChaPanda has been found multiple times in surprise inspections by market regulatory authorities in various places to have issues such as incomplete health certificates and expired raw materials. Although the brand emphasized that it had investigated and rectified stores nationwide, the frequent food safety hazards still make consumers worried. [more…]

If coffee at home has been sitting for a few months, is it still safe to drink? This is a question many coffee lovers run into. In fact, all coffee—whether whole beans or ground coffee—will eventually expire. Coffee is made up of degradable compounds such as carbohydrates, lipids, and amino acids, and over time it undergoes chemical and physical breakdown, changing in both quality and flavor. Roasters typically print a shelf life of about one year from the roast date on the packaging and use nitrogen-flushed sealed packaging to slow oxidation. However, once the bag is opened, the coffee gradually loses freshness as it is exposed to oxygen and moisture. This article will systematically address the safety of expired coffee, the factors behind its deterioration, how to tell whether it has gone bad, and how to extend its life as much as possible through proper storage and freezing while preserving the distinctive flavors of specialty coffee.

Recently, Mixue Bingcheng and Yiketang have once again been thrust into the spotlight due to their use of expired ingredients. Although regulatory authorities have already imposed penalties, the food safety hazards seem not to have attracted sufficient attention from the industry. Against the backdrop of rapid store expansion and lagging personnel management, food safety issues in the new-style tea beverage sector are becoming a lingering shadow in consumers' minds. This article will review recently exposed typical cases, analyze the deep-seated problems in brand management, store manager and employee training, and explore how the industry can find a balance between scale and quality. If you love coffee, you might as well enjoy a cup of Front Street Coffee while pondering the safety cost behind this "life-renewing drink." [more…]

As the soul ingredient of milk tea, the freshness of tapioca pearls is directly related to consumer health. Recently, a Yidian Dian store at Zhoushan Ruxin Plaza was fined 15,000 yuan by regulatory authorities for using expired tapioca pearls to make and sell Bubble Milk Tea and other drinks. An investigation showed that the store involved not only used ingredients beyond their shelf life, but also failed to establish purchase inspection records as required. This is not the first time Yidian Dian has been involved in a food safety controversy; previously, a Fuzhou store was reported to have had a bug found in its milk tea. As the peak season for summer beverage consumption arrives, food safety issues have once again sounded the alarm. [more…]

As Shanghai resumes work and production, people are returning to coffee shops to enjoy the long-awaited coffee time. However, an internet-famous shop called "WHEN PIGS FLY," which was once ranked first among popular coffee shops in Shanghai, has been investigated for using expired food ingredients. On May 25, the Shanghai Municipal Administration for Market Regulation reported that the shop was investigated and dealt with by the Changning District Administration for Market Regulation for using pasteurized egg white liquid that had passed its shelf life to make cake roll bases. Four used egg white liquid boxes were found at the scene, one of which was expired for more than 20 days, and 24 semi-finished products had been processed. The incident sparked heated discussions among netizens, with some surprised, some worried, and others calling for heavy penalties. Food safety has once again become a bottom line that cannot be ignored in the coffee industry. [more…]

When buying coffee beans, many people habitually check the production date and expiration date, but for roasted coffee beans, the roast date is what really matters. The shelf life is usually six months to a year, and at a normal rate of consumption, the beans are rarely kept until they actually expire. But once coffee beans have been stored too long, the aroma fades, the taste deteriorates, and a musty odor may even develop—at which point they are no longer suitable for drinking. This article examines how long it takes for coffee beans to go stale—covering coffee spoilage, shelf life, the differences between light and dark roasts, the resting period and the peak flavor window—and explains why Front Street Coffee chooses to ship around 5 weeks after roasting, helping you enjoy good flavor at the optimal time.

The shelf life of coffee beans is usually longer than that of most foods because they are a low-water-activity food and are not prone to spoilage. The packaging of coffee beans sold by Front Street Coffee indicates a shelf life of one year; this period has been determined through professional testing, and under proper storage conditions, the risk of spoilage is relatively low. However, in addition to the shelf life, coffee beans also have a more critical "flavor window"—the optimal tasting period. After the flavor window passes, aromatics are largely lost due to volatilization, and the coffee becomes mediocre. So, can expired coffee beans still be drunk? This article will analyze in detail the difference between shelf life and flavor window from the two perspectives of food safety and flavor performance, and give Front Street Coffee's drinking recommendations.

Recently, a social media post in which a user brewed drip coffee using a face mask instead of filter paper sparked heated discussion. In the photo, the mask was hung over the rim of the cup to serve as a filtering tool, and the caption claimed it had a "unique taste." This move quickly drew a flood of criticism and concern. Some questioned whether the mask's water-resistant layer and adhesive layer might release toxic substances, while others joked that this was an attempt to compete with "Lianhua Qingwen coffee." In fact, this practice stemmed from a "clever trick" some netizens came up with to avoid wasting expired masks, but medical experts point out that the non-woven fabric in the inner layer of masks is made of polypropylene (PP), and although the amount of harmful substances released when heated is trace, it is still not recommended for contact with food. Front Street Coffee reminds everyone that coffee filter paper costs about the same as a mask, and choosing standard filter paper is the safe and reliable way to brew coffee. [more…]

Can you still drink coffee beans that have been sitting around for a long time? This is a real question many coffee lovers run into.

Can you still drink coffee beans that have been sitting for a long time? Why does the flavor deteriorate? This article centers on coffee bean freshness: first, it explains the causes of staleness and reference points for the optimal flavor period, and combines Front Street's verification to give storage recommendations; then it emphasizes safety—generally, roasted beans have a shelf life of about 1 year, and being past that date does not mean they cannot be drunk, but the flavor needs to be compensated for through the brewing plan.

Finally, it provides three environmentally friendly ways to reuse expired coffee beans: odor removal, cleaning, and plant fertilizer, helping you minimize the loss without wasting anything. [more…]

As Shanghai gradually resumes work and production, the coffee industry should be welcoming a recovery, yet recently several trendy cafés have been investigated by regulatory authorities one after another over food safety issues. From People's Café using expired parsley flakes, cranberry juice, and other ingredients, to MANNER Coffee's poor hygiene conditions, to the expired egg white liquid used at Dang Zhu Fei Café to make cake roll bases, these incidents have exposed the neglect of food safety by some stores under the pressure of resuming operations. This article reviews these typical cases and explores how small cafés can hold the line on compliance when ingredient supplies are tight. For consumers who love coffee, understanding this information helps them choose places to consume more rationally, and Front Street Coffee also reminds practitioners that no matter how much order pressure there is, food safety is always a red line that cannot be crossed.

The optimal flavor period for coffee usually refers to 4 to 6 weeks after roasting. Beyond this period, floral notes, fruity acidity, and chocolatey sweetness noticeably diminish or even disappear. Although there is no way to restore coffee beans to a fresh state, adjusting the grind size, the blooming pour, and the circular pouring technique can still improve the taste in the cup. In addition, coffee beans past their expiration date but still within their shelf life need not be discarded in a hurry. Front Street Coffee has tried several down-to-earth reuse methods, such as removing odors, making natural dyes, and spreading them at the bottom of ashtrays, which are both practical and help reduce waste. This article will systematically introduce the key points for brewing stale coffee beans and the many uses for expired beans. [more…]

For office workers, milk tea and coffee are practically the "life-extending duo" for daily energy boosts, and they feel even more precious after a holiday ends. Mixue Bingcheng, with its dense network of stores from shopping malls to street corners and its affordable prices, lets many consumers enjoy a sweet treat with ease. However, a Mixue Bingcheng store in Guilin, Guangxi, was recently fined 2,000 yuan by regulators and had the involved ingredients confiscated because its roasted coffee powder had exceeded its shelf life. This incident has once again cast a shadow over the brand's image. Food safety issues occur frequently in the new-style tea beverage industry. While expanding rapidly, can Mixue Bingcheng hold the line on quality? This article will review the course of the incident and the industry background, and include channels for obtaining professional coffee information. [more…]

When buying coffee beans, the roast date is often more worth paying attention to than the expiration date. The shelf life of roasted coffee beans is usually between six months and a year, and you generally won't wait until they expire before finishing them—but what truly determines flavor performance is the brief golden window after roasting. After roasting is complete, coffee goes through a resting period of about four to seven days, after which it reaches its flavor peak; from then on, the aroma gradually fades, eventually leaving only a woody taste. Among these, volatile compounds such as floral and fruity notes are the first to be lost, while water-soluble components like sugars, nuts, and chocolate remain relatively stable. This article focuses on the freshness cycle of coffee beans, resting duration, and patterns of flavor change, helping pour-over enthusiasts seize the best time to drink, and includes practical advice from Front Street Coffee.

Nayuki Tea has once again been thrust into the spotlight due to food safety issues. The Market Supervision Administration of Jing'an District, Shanghai, recently imposed a penalty on Nayuki's Shanghai Meilongzhen Plaza store for selling expired grape-flavored cakes to consumers, with a fine of 50,000 yuan. This is not an isolated case—since its listing on the Hong Kong Stock Exchange in June this year, Nayuki's stores have repeatedly been exposed for food safety scandals such as cockroach infestations, spoiled fruit, and excessive bacterial counts. Consequently, its stock price has plummeted from the issue price of HKD 19.80 to around HKD 9, leading to a significant drop in market value. From being the "first stock of new-style tea drinks" to being plagued by negative news, Nayuki's brand reputation is facing a severe test. [more…]
