The victims fell ill after drinking the locally made liquor over the weekend in Garut and Sumedang districts, provincial police spokesman Martinus Sitompol said.
"Apparently the drink contained 90 per cent alcohol and was mixed with drugs and mosquito repellent," Sitompul said.
Police have arrested the distributor of the drink, he said.
Dozens of Indonesians die every year after consuming home-brewed drinks, often adulterated with a variety of toxic substances to increase their potency, including methyl alcohol and mosquito repellent.
