The Bhirombhakdi family, who've produced Singha beer at Boon Rawd since 1933, is following the lead of billionaire Charoen Sirivadhanabhakdi, who expanded his property business amid government measures to curb alcohol consumption. Mr Charoen was forced to list his Thai Beverage Plc unit in Singapore in 2006 after activists and monks held protests to block a local share sale by the maker of Mekhong whiskey.
