Must. Don't know an English word for it, but it looks like Coke but is made of some of the ingredients that beer is made of but it's non-alcoholic and pretty sweet. I think the closests you can come to the taste is American root beer, but it doesn't taste like root beer either...We drink it around Xmas, and then it's called
julmust and around Easter, when it's called
påskmust. 
was it something I said?
