Fiji
I have one sourced drink connected to Fiji. 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 Fiji
Signature drinks and regional ones, with the evidence behind each. A drink marked non-alcoholic has no alcohol in the traditional serve.

Yaqona (Kava)
IconicRegional drinkNon-alcoholic
Powdered or whole kava root mixed with water and strained, served from a legged wooden bowl called a tanoa, often carved from a single piece of wood, into a bilo, a coconut shell cup. A guest receiving a cup claps once with cupped hands, says bula and drinks it down, and the group claps three times. Sherman's Travel calls it mildly narcotic and not so much intoxicating.
Wikipedia says kava is called yaqona or grog in Fiji, is drunk at all times of day and is a cornerstone of Fijian culture. A visiting guest presents kava to the chief of the host village as a gesture of goodwill, and Sherman's Travel says the village chief drinks first and then kava is offered to everyone in the room.
Made with: kava root, water.
