The story originated from a home-sick mother. After her children had all grown up and left, she fulfilled her dream of learning coffee and roasting, and backed to the place used to nurture her, Puzi of Chayi. She started the first specialty coffee brand and named it after herself, Isa.

Meanwhile, her family united ever since the cafe was about to begin. Her daughter took the part of patisseries and pastries, and endowed the cafe with its signature foods. The son worked on coffee with mom and even imported the latest oversea knowledge and technology to the cafe and roastery. Also, he won the cup taster championship in 2019.

They reunited because of the shop and ran the business together. Here, they put their heads together and shined the brand out. Currently the two branches became a name in Puzi, Chayi and are spreading out to more and more coffee lovers.
