i make glogg throughout the holidays and the drinks are related but not quite the same
you can buy the commercial version of julmust at ikea usually in their cafeteria/food store
you can also get it at cost plus world market
it looks like this:
i just scored some in the off-season (not christmas)
good stuff really
sugar malt hops coloring and flavoring (tastes like fig or prune or pear)
ill take a look at the label and try to hack it out
or order it from here
the julmust i get here (sweden) doesn't taste anything like malt or hops to me. it tastes more like a soda. (but then again i don't really drink much of it, so what do i know) i usually drink the julöl (christmas beer)
Svagdricka on the other hand is much more beer-y in flavor. and i think it is actually made with some kind of grain
