Introduction:Luckin Coffee recently launched a new regional-exclusive drink in Shanghai — the Lactic Acid Bacteria Americano, which combines plant-based lactic acid bacteria with cold brew coffee. Marketed for its refreshing and palate-cleansing qualities, it has sparked discussions due to its potential “gut-friendly” effects. This article delves into the formulation features, market feedback, and real-world experience of this new beverage, helping readers determine whether it’s worth trying and who it might suit best.

Luckin Coffee has quietly introduced an innovative iced drink — the Lactic Acid Bacteria Americano — in its Shanghai stores, drawing considerable attention from consumers. This regional-exclusive beverage blends plant-based lactic acid bacteria with Americano coffee, claiming to deliver a refreshing taste and aid in post-meal digestion. However, because both lactic acid bacteria and caffeine can potentially stimulate intestinal motility, netizens have jokingly dubbed it the latest “gut-smoothing wonder,” sparking heated discussions on social media.

According to current information, this new product is currently only available at Luckin stores within Shanghai and is part of a limited-edition iced drink series. The official description mentions that the drink contains imported patented plant-based lactic acid bacteria, with an overall flavor profile that is sweet and tangy. It emphasizes a “refreshing and palate-cleansing” drinking experience, making it suitable for hot weather or after meals, offering coffee lovers a unique alternative.

In fact, the combination of lactic acid bacteria and coffee is not entirely new in the world of creative coffee. Many coffee enthusiasts have long experimented with mixing yogurt or Yakult with espresso to create their own tangy-flavored custom drinks. As a result, for consumers who regularly follow coffee innovation trends, Luckin’s Lactic Acid Bacteria Americano may seem somewhat less surprising, with some netizens feeling its level of innovation fell short of expectations.

Feedback from actual tastings has been polarized. Some consumers pointed out that the prominent sourness of the lactic acid bacteria tends to overshadow the coffee aroma, which should be the star of the drink. For those unaccustomed to acidic beverages, it may be harder to accept. However, users who prefer a refreshing taste have given positive reviews, suggesting it’s suitable for summer or when a clean, crisp flavor is desired. They also recommend that visitors to Shanghai try it for themselves.

Notably, beyond its flavor, one of the key points of online discussion about the Lactic Acid Bacteria Americano is its potential “gut-smoothing” side effect. Some netizens observed that lactic acid bacteria naturally promote intestinal movement, and caffeine has similar physiological effects. When combined with the ice typically found in the drink, these three elements seem to “stack up” for bowel movement support.

Some consumers even joked that they don’t buy Luckin primarily for the caffeine boost, but rather in hopes of maintaining good gut function through specific drinks. Upon hearing about the “lactic acid bacteria + Americano” combo, many felt it sounded like a gut-health-focused “bowel-moistening beverage,” and even speculated that Luckin might roll out more health-oriented coffee products in the future.

Based on feedback from those who tried it, some users reported noticeable intestinal responses within an hour of drinking, with some even saying its effects were more significant than Luckin’s previously released Prune Americano. However, so-called “iron guts” consumers mentioned feeling no difference even after drinking two cups a day, indicating that its “smooth-moving” effects may vary by individual constitution and aren’t universally the same.

While some Shanghai users feel that the Lactic Acid Bacteria Americano doesn’t have as immediate an effect on “promoting gut health” as the once sensational “Pupu Water,” fans in other regions remain highly interested in this new drink, eagerly hoping the brand will roll it out nationwide soon so more people can experience its unique flavor and potential added benefits.
