If the brewed espresso isn't finished on the same day, can it be safely stored in the fridge or freezer overnight and still be enjoyed the next day? Beyond food safety concerns, what coffee lovers really care about is whether the flavor will take a serious hit. Front Street Coffee used the same espresso blend, storing espresso in the refrigerator and freezer overnight respectively, then comparing them with freshly brewed espresso—tasting each as straight espresso, Americano, and milk coffee—to see just what overnight coffee turns into, and how big the gap is between freezing and refrigerating.

Many people hesitate when ordering: should a latte be hot or iced? And how long do you have to finish an Americano?

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…]

Starbucks partnered with Stayreal, the streetwear brand co-founded by Mayday lead singer Ashin and Taiwanese artist No2Good, instantly igniting the enthusiasm of the band's fans and netizens alike. The online limited-edition themed cups were snapped up by tens of thousands of people the moment they went on sale, with the official app and mini-program lagging due to overwhelming traffic. Some users failed to complete payment and missed out on the cups they wanted, sparking complaints. Meanwhile, the limited-edition Starbucks gift sets released at physical stores, thanks to their relatively low threshold for acquisition, attracted a large number of fans who queued up with stools in the early hours of the morning. This collaboration craze showcased the fans' frenzy while also exposing the inadequate capacity of online channels and the controversy over offline queuing rules. [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…]

Luckin's Orange C Americano has always been a favorite among many coffee lovers, winning a large number of loyal fans with its refreshing, sweet taste. However, recently this popular drink has received negative reviews from consumers due to the orange sauce becoming thicker in texture and the taste being too sweet and cloying. Luckin responded quickly, requiring stores to thaw overnight and destroy the problematic batches of orange sauce, while urgently removing the Orange C Americano from the ordering platform. This move sparked heated discussion among netizens: some worry that this drink will disappear for good like previously discontinued flavored coffees, while others feel it is a pity to destroy so many raw materials. Luckin employees revealed that the orange sauce will be replaced, and in the short term most stores may not be able to sell the Orange C Americano. Whether this adjustment can bring the "white moonlight" back to its original taste remains to be seen by consumers. [more…]

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

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.

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.

Starbucks China recently announced the launch of its "True Flavor, Zero Sugar" innovation system across stores nationwide, splitting classic flavored syrups into zero-sugar flavor concentrates and separate original syrups, allowing flavor and sweetness to be customized separately, and adding two new flavors, "Berry Berry" and "Pandan." However, with the rollout of the new policy, staff at stores nationwide were required to centrally destroy old syrup inventory after closing on the 7th, with classic flavors such as vanilla, hazelnut, and salted caramel poured down the drain. This sudden "one-size-fits-all" sugar swap not only marks the beginning of Starbucks' flavor customization era, but also leaves many baristas lamenting the end of an era. [more…]

At the start of May, two pieces of earnings warnings from industry giants came one after another in the coffee sector. Starbucks suffered an intraday plunge of nearly 18% in U.S. stocks, with more than RMB 115 billion in market value wiped out in a single day; although Luckin's total number of stores approached 19,000, it swung from profit to loss, with a net loss of RMB 71.42 million.

The ingredient cost of an iced Americano may be only 1.5 yuan, and a coconut latte is just 4.2 yuan. Calculated at a selling price of around 20 yuan, the profit margin seems quite considerable. Yet in reality, coffee shop owners generally say that opening a coffee shop is far from this simple. Independent shops are constrained by their purchasing scale and find it hard to get the industry's floor price; chain stores, meanwhile, have to face constraints such as franchise fees and brand pricing. Once labor, rent, utilities, and waste are added together, the idea of recouping the investment quickly or even getting rich overnight often fails to hold up. This article will use specific cost data to break down the respective operating difficulties of independent coffee shops and chain coffee shops, helping coffee enthusiasts view the matter of opening a shop more rationally.

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.

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…]

Recently, the Maan Coffee branch at Chongqing Fuyuehui was reportedly forcibly demolished by the mall owner late at night. The store's equipment and furnishings vanished overnight, the interior was smashed, the entrance was barricaded, and advertising posters for the next tenant were already put up. The shop owner claims to have signed a ten-year lease with the mall, currently only in its fifth year, and has always paid rent and utilities on time, never defaulting even during the pandemic. After the incident, the owner called the police and posted a notice promising to refund customers' prepaid balances. However, some netizens expressed doubts about the poster's account due to last year's Maan Coffee runaway incident in Beijing. The operator clarified that the store had switched to independent operation and had nothing to do with the brand. Furthermore, a former tenant came forward alleging that the mall had repeatedly forcibly evicted tenants before their leases expired. The incident continues to escalate, and the mall has not yet responded. [more…]
