Nongpho milk reported a sharp increase in sales after Lisa of Blackpink fame and her friends recently posted a video showing them drinking the chocolate milk on Instagram.
The chairman of Nongpho Dairy Cooperative thanked K-pop singer Lalisa "Lisa" Manoban for helping to popularise milk on social media.
"Orders for Nongpho dairy products have increased three-fold," he said.
The Nongpho factory in Ratchaburi can produce 300 tonnes of dairy products a day. The company buys raw milk from 5,000 local farmers.
On June 12, Lisa posted a clip of chocolate-flavoured Nongpho milk on her Instagram story and was later tagged in her friend's Instagram story while holding a carton of Nongpho milk.
Both Instagram stories were posted as screenshots on the Blackpink YG Thailand Facebook by her fans.
Thailand is the largest manufacturer of unpasteurised milk in Southeast Asia. Yet Thai people drink just 18 litres of milk per year on average, compared to 60 litres per year in Southeast Asia overall and 103.9 litres a year globally.
