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

Malt og Appelsin
Christmas season
IconicRegional drinkNon-alcoholic
Two Icelandic sodas mixed in a glass: Appelsin first, then malt extract soda, to keep the foam down. It is the Icelandic Christmas drink, also called jolaol, and is sold premixed. No ratio is given in the opened source.
Wikipedia dates Appelsin to 1955 from the Egill Skallagrimsson Brewery and says it is traditionally mixed with Malt at Christmas, as jolaol. The sources opened give no date for the mix. A retailer lists Egils Malt as non-alcoholic, which is why the drink is listed as not alcoholic.
Made with: malt extract soda (Malt), orange soda (Appelsin).
