What Is Coffee Made Out Of, and Why the Yak Milk Drink Changed
Heytea's limited Yak Milk Cha-An-Mo, launched at the end of last month, drew repeat buyers who reported the drink tasted different on a second visit: the milky aroma had weakened and the tea flavor came forward. Store staff told customers the recipe was altered on the morning of the second day after launch and fine-tuned again later, a change the brand did not announce publicly.
Yak milk itself has limited production, and many stores sold out quickly, with the official line that the item would come off the menu once ingredients ran out. The silent adjustment left some consumers feeling the delivered cup did not match the promotion, and staff worried they would be blamed for cutting corners. Knowing what is coffee made out of, and what goes into a milk tea, helps drinkers judge such shifts in ingredients.
Heytea's limited-time new product last month, Yak Milk Cha-An-Mo, quickly became popular thanks to the unique flavor of Tibetan yak milk, but it was in short supply due to scarce ingredients. However, recently, many repeat customers found that the drink's taste was very different from their first try—the milky aroma had become weaker and the tea flavor more prominent. When they checked with store staff, they unexpectedly got the answer that "the recipe was changed on the morning of the second day after launch." Employees also revealed that further fine-tuning was done afterward. This silent recipe change has sparked consumer dissatisfaction, as they feel the actual taste does not match the promotion and that it may cause store employees to be misunderstood as "cutting corners."

At the end of last month, Heytea launched a limited-time new product called Yak Milk Cha-An-Mo in stores nationwide, sparking strong interest in this specialty milk tea from Tibet, and many people rushed to order it to try this uniquely flavored drink.
However, because yak milk itself has limited production, many stores soon faced shortages and sold out of the limited-edition item. The official side also stated that once the ingredients for this product are used up, it will naturally be taken off the menu, and it is difficult to determine when it will return. This made fans who love Yak Milk Cha-An-Mo realize that if they did not drink it soon, they might miss their chance, so they rushed to buy a cup before nearby stores posted sold-out notices.
But recently, some consumers who repurchased Yak Milk Cha-An-Mo received their freshly delivered drinks, took a few sips, tasted them carefully, and then began to doubt the flavor in the cup: "Is this still the same Yak Milk Cha-An-Mo I drank last time?"
Some customers recalled that when they first drank this new product, the milky aroma was rich and the milk cap was thick and creamy, leaving a very deep impression. But the second drink they bought had a noticeably weaker milk flavor, and almost all they could taste was tea, making them wonder whether there had been a mistake in the ingredient ratio during preparation, causing such a big difference in flavor.
It is worth noting that this consumer was far from the only one who noticed a change in the taste of Yak Milk Cha-An-Mo. Others commented that the drinks they had recently bought were completely different from the flavor when Heytea first launched it: the milk flavor was weaker and the tea flavor dominated, and some even mistakenly thought they were drinking Assam milk tea.
Faced with this situation, consumers full of questions went to the store to ask Heytea employees and got a rather unexpected answer: "The recipe was changed on the morning of the second day after launch."
Some employees revealed that on the second day after the new product was launched, they received a notice from headquarters correcting the preparation method for Yak Milk Cha-An-Mo, and admitted that "now it is just an ordinary light milk tea, the same as Xiao Nai Mo, only with a different tea base and milk base, plus a milk cap." Other employees said, "Actually, after the recipe was changed on the second day, it was fine-tuned again on the third day," making further adjustments to the ingredient ratio.
After getting answers from Heytea employees, many netizens suddenly understood: "It really is not as good as it was on launch day; now the taste is very ordinary," "No wonder it tastes so unremarkable," "No wonder the second time I repurchased it, it was not as good as the first time I ordered it, from an obvious black tea aroma to hardly any tea flavor," "The first day my eyes lit up! The second day my eyes went dark!"
Some people were quite disappointed with the adjusted drink and said bluntly that the current Yak Milk Cha-An-Mo tastes similar to other milk teas Heytea sells, losing the stunning feeling of the first taste and instead seeming bland.

In addition, some netizens believe that Heytea quietly changing the recipe on the second day after the drink was launched will make the actual taste consumers get differ from the flavor promoted by the brand; at the same time, it can easily make repeat customers mistakenly think that store employees cut corners during preparation, creating unnecessary misunderstandings and bringing negative reviews to the stores.
