From "Dark Cuisine" to Sold Out: Why This Cup of Milk is Sweeping the Internet

A single, humble cup of milk — once joked about as "dark cuisine" — has become the latest viral commodity in China's short‑video era. Videos and posts showing the drink and quirky ways to prepare or enjoy it have spread across Douyin (抖音) and Xiaohongshu (小红书), turning what began as a meme into real consumer demand. It has been reported that retailers and online merchants scrambled to restock after the wave of clips; many outlets reportedly listed the product as sold out within days.

The viral jump

Short‑form platforms are built to amplify simple, repeatable actions. A handful of creators posted quick, shareable clips; the algorithm did the rest. View counts reportedly climbed into the millions, and creators added commerce links directly into livestreams and product pages on Taobao (淘宝) and other marketplaces, closing the loop between discovery and purchase. Why do viewers buy a cup of milk? Novelty, relatability, and the pleasure of participating in a meme — packaged as a low‑risk impulse buy.

Why it matters

This episode is a small but telling case study of China's digital ecosystem: platforms, creators, and e‑commerce tightly integrated, capable of turning cultural oddities into commercial frenzies overnight. For brands and manufacturers, it shows how fast demand can spike — and how fragile supply chains can be in the face of viral attention. For observers outside China, it’s a reminder that attention on Douyin and Xiaohongshu translates into real economic effects, not just online chatter. What started as a joke becomes a business in hours — and then a shortage. Who ultimately benefits: the platform, the micro‑influencer, the producer, or the consumer? That question remains partly unresolved.
