Luckin Coffee's SOE Little Black Cup series has always presented itself as a single-origin specialty line, with beans like Yirgacheffe, Huakui, and Geisha maintaining consistently high popularity, priced 20% to 30% higher than regular coffee, with its 12oz small cup size and rich flavor as its signature. However, this Monday, Luckin suddenly added a 16oz size to its SOE product line, allowing the Yirgacheffe Little Black Cup to be upgraded for free to a Big Black Cup for a limited time, covering three classics: Americano, Latte, and Aussie White. The increase in volume at no extra cost seemed like a good deal, but many longtime fans discovered after ordering that the coffee concentration had plummeted, with the Yirgacheffe flavor almost completely gone, and complaints like "watery and bland" and "the upgrade just adds water" flooding social media. Staff later explained that the coffee powder weight had indeed increased, but the increment was far from enough to match the difference in cup volume, and could only be made up with water or milk. For those who prefer a rich taste, Front Street recommends going back to the original Little Black Cup. [more…]
