In the country, high taxes make it expensive and some people can turn to potentially dangerous home-made liquor.

The government-run Subang district general hospital in West Java province admitted 18 victims for "alcohol intoxication" on Saturday, said hospital spokesperson Wawan Gunawan. 

"There are five people under observation and 11 people died (at the hospital)," Wawan told AFP Monday, adding that the victims were aged between 16 and 45 years old. 

Another victim was pronounced dead on arrival at the hospital, Wawan added. 

The victims died after buying the bootleg booze to be consumed at a wedding party on Saturday, according to a local police report.

Four of the victims were in critical condition and one was recovering, said Wawan.

Police have arrested a suspect in connection with the incident, said Subang police chief Adj. Sr. Comr. Ariek Indra Sentanu. 

Local media reported a thirteenth victim had died after their family requested an early discharge from the hospital, but Wawan could not confirm their status.

In 2018 more than 60 people died from drinking cheap home-made alcohol with police conducting raids across the country to arrest more than half a dozen vendors, including one who mixed mosquito repellent into his concoction. 

In 2016, 36 people died in Central Java after drinking locally-brewed alcohol.
