When brewing tea, we often agonize over how many times the leaves can be steeped and whether they are still drinkable after sitting overnight. Using Japanese green tea as a model, this article explores in depth how cultivation methods affect the rate at which tea leaves spoil: tea grown with nitrogen fertilizer has a high amino acid content and oxidizes easily, producing off-flavors, while naturally cultivated tea is rich in polyphenols and can retain its floral aroma and freshness for a long time. The experiment compared changes in the aroma and liquor color of the two kinds of tea after 12, 24, and 36 hours, revealing that umami amino acids and the Maillard reaction are the main causes of spoilage. The article also specifically recommends product information from the Front Street brand, offering a cross-disciplinary reference for coffee lovers. Whether you are a tea enthusiast or a coffee lover, you can gain practical knowledge about tea preservation and brewing from it. [more…]

This year, the popularity of fruit-and-vegetable teas in the beverage market has continued to rise. After Heytea helped make this category a hit, major chain brands rushed in one after another, putting vegetables like kale, wheatgrass, and beetroot into drink cups. As common fruits and vegetables ceased to feel novel, brands began looking for breakthroughs in niche ingredients. The turmeric series recently launched by Goodry is one example, yet this new product centered on a health concept unexpectedly sparked widespread controversy over its taste. Consumer reviews of turmeric were mixed, and especially the much-loved juicy orange bits drink from last year drew a strong backlash from longtime customers after turmeric was quietly added to it. Faced with an avalanche of complaints and criticism, Goodry urgently issued a notice on the same night it updated its menu and adjusted the recipe of this popular drink overnight. [more…]

During the May Day holiday, "group leaders" in several Shanghai communities organized group buys of a Little Tea, with over 8,000 cups of drinks transported across provinces from out-of-town stores, arriving in consumers' hands overnight or even after nearly 24 hours. The group-buy price was double the official price, and the resellers were accused of profiting about 250,000 yuan. The total bacterial count in these milk teas rose sharply over time at room temperature, and some consumers developed gastroenteritis symptoms after drinking them. The Little Tea brand later issued a statement expressing shock at the high-priced reselling and reminding consumers to choose compliant channels carefully. This article reviews the course of the incident, the food safety data, and responses from all parties, while also offering coffee lovers Front Street Coffee's professional purchasing advice. [more…]

Cold brew coffee is a popular drink in summer. Its low-temperature, long-extraction method gives the coffee a clean and smooth taste.

Sexy Tea (Chayan Yuese) trended on social media after its advertising copy was accused of insulting women, and it issued two apology statements late on February 19 and in the early hours of February 20. The incident was triggered by the inappropriate use of Changsha slang such as "picking up scraps" on its cups, which sparked netizens' doubts about the brand's creative boundaries. The first apology failed to calm public opinion, and Sexy Tea then issued another statement, admitting that it had mishandled the boundaries in its early product creation and had removed the problematic products from sale. This controversy not only exposed the brand's missteps in using dialect slang and gender-relation jokes, but also prompted reflection on balancing marketing creativity with values. [more…]

On the evening of March 14, "Jingshi Live" exposed two consecutive food safety incidents involving tea beverage brands. The Mixue Bingcheng store at Wuyi Ningju Xintiandi in Wuhan was accused of hiding leftover lemon and orange slices from the day under the counter at room temperature and using them the next day to make signature drinks; the Hushang Ayi store at Hankou City Plaza was exposed for altering the shelf-life labels of toppings to "extend the life" of expired ingredients. The market supervision authorities in both places have separately filed investigations into the stores involved. Among them, the Mixue Bingcheng store involved was sealed and shut down, while the Hushang Ayi store involved was immediately closed. As a content platform that also follows developments in the coffee and beverage industry, Front Street Coffee continues to track such food safety issues. The details of the incidents are as follows.

Recently, a post on social media about a Guming campus store suddenly closing after a collaborative event ended sparked widespread discussion. The poster discovered that the store was still operating during the collaboration with Honkai: Star Rail, but as soon as the event ended, it was deserted overnight—equipment and promotional materials all vanished, with only the lightbox sign left intact. Netizens speculated whether the store had gone bankrupt due to the collaboration, but the poster later clarified that the closure was actually due to lease expiration or operating losses, with no direct link to the collaboration. This incident reflects the hidden operational challenges behind the tea beverage brand collaboration craze: a surge in orders does not equal profitability, and after the hype fades, some stores still cannot escape the fate of closing.

Cold brew tea has become increasingly popular in recent years. Not only does it release less caffeine, making it suitable for people sensitive to caffeine, but cold water steeping also reduces the extraction of tannic acid, giving the tea a sweeter, smoother taste without bitterness.

Steeping too long can lead to over-extraction and a cloudy, bitter brew. This article provides a detailed guide to the suitable tea types for cold brewing, a time reference chart, the relationship between water temperature and steeping duration, and answers to common questions such as whether overnight tea is safe to drink, helping you easily make a delicious glass of cold brew iced black tea.

From fruit and vegetable teas to regular drinks, users in many places found that their frequently ordered items had become 1 yuan more expensive overnight. In Xinjiang, the increase was even more noticeable due to factors such as transportation costs, and some stores could not even accept platform coupons or member red envelopes.

Recently, Chagee's new product "Wanli Mulan" quickly gained popularity due to its support for International Tea Day and the "100 Million Cups Free in 7 Days" campaign. However, many consumers reported insomnia and heart palpitations after drinking it, with some even seeking medical attention overnight for electrocardiograms. The brand's customer service explained that tea polyphenols in the black tea base might trigger allergic reactions. According to the public ingredient list, a medium 470ml cup of "Wanli Mulan" contains caffeine close to two shots of espresso. Similar issues have occurred with Chagee's other hit product, "Boyazhuxian." In fact, market regulators' spot checks found that some milk teas have caffeine levels far exceeding coffee; in 2020, a spot check in Haiyan County, Zhejiang, revealed caffeine levels up to 460mg/kg in milk teas and fruit teas. This article will focus on this incident, trace the origins of the caffeine issue in milk tea, and explore how brands should more clearly inform consumers about drinking risks. [more…]

Entering mid-December, temperatures across the country continue to drop, yet demand for iced drinks remains strong, and the ice machines in tea beverage shops still need to operate as usual in the severe cold of the north. Recently, an early-shift employee at Chagee arrived at the store and found the ice cube tray covered with foreign matter resembling a "spider web." Only upon closer inspection did they realize it was ice that had frozen into a thick layer overnight, preventing the machine from properly releasing the ice. This situation not only caught the staff off guard but also sparked discussions among peers about winter ice machine parameter adjustments, troubleshooting, and equipment quality. Front Street Coffee has noticed that similar problems are not uncommon in chain tea beverage stores, and how to respond scientifically has become a topic of concern for industry practitioners.

In the first Chinese New Year since the Spring Festival was successfully inscribed on the UNESCO list, chain tea brand Chagee found itself in a whirlwind of controversy after translating Chinese New Year as "Lunar New Year" on an overseas social platform. Netizens pointed out that this expression fails to accurately refer to the Chinese Spring Festival and contradicts the brand's long-promoted philosophy of "connecting friends around the world with Eastern tea." Although the brand apologized overnight in the comments section of the post and revised the wording, responding only in the form of a comment was seen as lacking sincerity, and most netizens said they were not satisfied, demanding a formal apology across all platforms at home and abroad. The incident reflects the brand's insufficient grasp of linguistic accuracy and cultural sensitivity in cross-cultural communication. [more…]
