Being from Sweden I got pretty exited by looking at this site that says it reviews beverages from all sorts of places. So I started to look if they had reviewed the Swedish no 1 holiday beverage that is called Julmust. But no luck.
Anyway this beverage is so popular in Swe. so it even make Coca Cola sales drop during X-mas when it is availible

Kristall Soda is a really excellent Swedish soda here in the Us. Have you tried it?

They are selling Julmust at IKEA, would have tried it but the lines at the swedish food area were too friggen long. Oh well, maybe next time.

Bringing the Swedish Classic- Blabar to North American Ski towns.
It's a traditional hot blueberry beverage closely associated with
cross country skiing. Been serving it up by the cup here in Lake Tahoe, Ca. since season open.
It's climbing the charts. Watch out Hot Chocolate!
