Introduction:Manner collaborated with the Power Station of Art (PSA) in Pudong to launch a caramelized burnt toast-flavored latte and a limited-edition tote bag, which garnered an enthusiastic response from consumers. However, some drinkers reported experiencing gastrointestinal discomfort symptoms such as diarrhea and vomiting, making this new product the center of discussion. This article delves into the characteristics of the latte, actual consumer experiences, and possible reasons for the discomfort, helping readers gain a more comprehensive understanding of this seasonal beverage.

Manner and the Power Station of Art have joined forces once again, this time drawing inspiration from the famous work of British Romantic painter J.M.W. Turner, “The Blue Rigi, Sunrise,” to release a limited-edition artistic tote bag and a brand-new caramelized burnt toast-flavored latte. Since the limited set went on sale, the oil-painting-textured tote bag has quickly become a must-have item for social media photo opportunities, sparking a buying frenzy among fans.

This is not the first collaboration between Manner and the Power Station of Art. As early as December last year, the two parties launched a limited-edition peripheral collection themed around Manet’s “The Rider: Woman on a White Horse,” where the tote bag was also highly sought after by art enthusiasts. This new creation continues the art crossover style—featuring not only an eye-catching design but also successfully attracting a large number of consumers to stores to purchase the limited set.

However, with the launch of this caramelized burnt toast-flavored latte, another wave of discussion has emerged online. Many consumers reported experiencing gastrointestinal discomfort symptoms such as diarrhea, vomiting, and even “vomiting and diarrhea” after trying the new flavor latte. One netizen mentioned that they and their friend bought the set just to collect the beautiful merchandise, but ended up frequently rushing to the bathroom shortly after drinking, which came as a complete surprise.

In fact, this latte belongs to the flavored latte series, flavored with caramel as the base. Many candidly admitted that just hearing the name “caramelized burnt toast” intuitively suggested it would be very sweet, leading them to be cautious about the sugar content. However, according to multiple customer feedback, baristas typically adjust the syrup ratio based on customer preferences, and the actual taste wasn’t as overly sweet as expected, with the flavor being quite acceptable.

What really came as a surprise were the physical reactions after drinking. One consumer described in detail: “From yesterday morning until now, at least 10 times, and it felt like everything I ate came out completely unchanged.” “It was a total mess, I thought I had eaten something bad.” “I drank one this morning and had to go three times.” “Drank it and had vomiting and diarrhea, still haven’t recovered yet.” These posts quickly resonated with others, with many netizens commenting that they had experienced similar issues.

In response to these reports of gastrointestinal discomfort, various speculations have emerged online. Some consumers suspect that in addition to regular fresh milk, the latte may have additional thick milk or other dairy products, causing noticeable discomfort in those who are lactose intolerant. Others suggest that if the drink is served cold, it might irritate the stomach, placing an extra burden on those with more sensitive digestive systems, thereby triggering symptoms like diarrhea.

Although the new product features an eye-catching design and the merchandise is highly sought after, the uncomfortable experience after drinking has led many to say they’d “rather not drink it.” Some netizens even jokingly referred to the latte as a “laxative miracle,” playfully claiming it indeed gave them a “full-body cleanse”—of course, this is meant as a joke, but it reflects the consumers’ concern for beverage safety and bodily reactions.

Interestingly, some users who have long suffered from constipation became eager to try it after seeing the discussions, hoping the latte might improve their intestinal condition. Although this approach is unscientific, it does demonstrate the topicality and influence of this seasonal beverage.

In summary, Manner’s collaboration this time achieved good feedback in terms of art and brand synergy, with the limited-edition tote bag successfully appealing to both art and coffee enthusiasts. However, the gastrointestinal discomfort issues caused by the caramelized burnt toast-flavored latte also serve as a reminder for consumers to pay more attention to their own physical conditions and the ingredients of novel-flavored beverages when trying them out, in order to enjoy coffee while maintaining a healthy and comfortable experience.
