Recently, multiple Luckin Coffee users on social platforms have reported that their go-to Little Butter series drinks have developed a distinct mutton-like gamey odor. The series was launched last October in a collaboration with the Thai IP Butterbear, and during a second collaboration in February this year, it was announced that the New Zealand butter would be upgraded to French President butter. It had once been highly popular for its popcorn-like sweet and fragrant flavor. However, from Jiangsu, Zhejiang, and Guangdong to Shaanxi and Chongqing, consumers across various regions have posted that the Little Butter Latte and Little Butter Americano they recently purchased carry an unacceptable fishy, gamey smell, whether served hot or cold. Luckin's customer service did not directly respond to whether the formula had been adjusted, and store employees also denied that ingredients were expired or that preparation methods had changed. Whether it is due to differences in raw material batches or other reasons, there is still no official conclusion. [more…]

In recent years, more and more coffee enthusiasts have chosen to buy their own espresso machines at home, starting with espresso and gradually mastering the preparation of drinks like lattes, latte art, and dirty coffee. Recently, a netizen tried to recreate the butter latte commonly seen in coffee shops at home. To skip the wait for butter to soften at room temperature, they had a sudden idea: put a block of butter directly into the portafilter and tamp it together with the coffee grounds for extraction. This method sparked a nationwide copycat challenge, but the results often ended in failure—the butter was squeezed into thin strips by the pressure and shot out from the bottomless portafilter, coffee liquid splattered everywhere, and the countertop was left in a mess. Onlookers joked that the espresso machine had switched careers to become a pasta maker. This article fully documents the process of this creative experiment, the real feedback from netizens, and warm reminders from experienced individuals. If you're also tempted to try it, you might want to first read this compilation by Front Street Coffee before making a decision. [more…]

Luckin Coffee's co-branded campaign with the popular IP Butterbear launched on September 30, introducing four themed cups and a Little Butter drink series that drew widespread attention from fans. However, after the campaign began, many consumers reported that orders placed through third-party platforms such as Ele.me did not come with the co-branded stickers, which was inconsistent with the official promotion's promise of "free with any 2 cups." Customer service responded that peripherals could only be obtained by ordering through the Luckin App or mini-program, prompting consumer questions about the lack of transparency in channel rules. The incident reflects the problem of inconsistent messaging in brands' multi-platform marketing and serves as a reminder that consumers should carefully confirm giveaway conditions before placing orders.

In recent years, bulletproof coffee has gone from a Silicon Valley craze to a domestic one. Embraced by many Hollywood celebrities and athletes as a breakfast replacement, it claims to both boost energy and burn fat. Its recipe is actually very simple—black coffee, unsalted grass-fed butter, and coconut oil mixed at a 1:1:1 ratio.
