Nepal
I have one sourced drink connected to Nepal. The label on each card says how: where it began, what the country is known for, what people drink there, or where the origin is disputed.
Drinks of Nepal
Signature drinks and regional ones, with the evidence behind each. A drink marked non-alcoholic has no alcohol in the traditional serve.

Tongba
Eastern Nepal (Limbu)
IconicRegional drink
Fermented finger millet placed in a hollow bamboo vessel and covered with boiling water. It steeps for a few minutes and is sipped through a fine bamboo straw whose base filters out the grains. The same millet takes several refills of hot water, each round milder than the last.
Wikipedia calls tongba the traditional drink of the Limbu people of eastern Nepal and the neighboring Indian regions of Sikkim and Darjeeling. Offering it to a guest is a sign of respect, and at weddings the couple shares it as part of the ceremony.
Made with: fermented finger millet, hot water.
