The story of Hoi An Mot drink originates from a young man named Nguyen Huu Xuan, born in the 1990s, in Hoi An Ancient Town, Quang Nam Province (now Da Nang City). Mr. Xuan's family owns the An Thai Ong Thay Tai herbal medicine store – a traditional medicine shop over 100 years old located right on Tran Phu Street. Since childhood, he observed his grandfather preparing herbal prescriptions and learned about traditional medicine formulas.
In 2013, Mr. Xuan began experimenting with brewing a drink based on the family's traditional "An Thai Ong Thay Tai" recipe, combining locally available ingredients such as lemongrass, lime, and herbs. The initial goal was simply to create a refreshing drink for his family during hot summer days. However, its special flavor quickly spread, and he decided to sell it at a small stall in front of his house. The name "Mot" is not derived from "mat" (cool/refreshing, as many wrongly assume), but is actually Mr. Xuan's childhood nickname – simple, warm, and easy to remember for both domestic and foreign tourists.
From a homemade drink, Mot drink quickly became a specialty of Hoi An, attracting thousands of check-ins on social media. Today, Mot Hoi An shop has become a familiar stop, contributing to the ancient town's culinary map.
