History
While touring Europe in 1979, Alfredo Yao learned about the Doypack packaging format in one of the European trade exhibits he visited. He bought one machine and tried to market the Doypack packaging format to juice drink manufacturers in the Philippines. When no company took interest, he decided to market his own brand of fruit juice drink. He put up a company called SEMEXCO Marketing Corporation and launched Zest-O orange juice drink in 1980.[1][2]
Zest-O Cola, Zest-O Dalandan & Zest-O Calamansi carbonated soft drinks were introduced in 2000 while Zest-O Root Beer was introduced in 2005.
