Apo (drink)
Apo or apung is an alcohol drink popular among the tribes in the North East Indian states of Arunachal Pradesh and Assam. It is prepared by fermentation of rice. It is generally distributed among the participants in a bamboo shoot.
The Nyishi people, who form the national part of the local tribal population in Nirjuli, celebrate Nyokum annually. They serve the local drink, apung. The Nyishi people offer the drink, every time they drink it, to the spirits by letting few drops of it fall on the ground.
