Tanduay Distillers, Inc. is an Philippine alcoholic beverage company that is a subsidiary of Lucio Tan's conglomerate LT Group. As of 2019 it is the world's largest rum brand.
Tanduay traces its origins to a distillery in Hagonoy, Bulacan originally owned by Elías Menchatorre. In 1856, the distillery was acquired by Valentin Teus e Yrisarry and brought into Ynchausti y Compañía, a prominent Philippine multi-national conglomerate led by the Ynchausti family. By the 1900s, production would shift to the Manila distillery. By the 1930s, the rum it produced became branded as Tanduay Rhum and its packaging was changed from the 10 gallons dama juana container to the smaller (375 ml, 750 ml) glass bottles.
In March 2020, during COVID-19 pandemic the company starts producing Ethyl Alcohol with Absolut Distillers, Inc. for hospitals to help the alcohol shortage in medical facilities.
Out of all the Rum Brand Champions, Philippine rum Tanduay was the only million‐case brand to report double‐digit growth, securing the top accolade of Rum Brand Champion 2021. Tanduay managed to grow volumes from 20.5 million cases in 2019 to 23.9m cases in 2020 – a 16.6% increase.
