Although the woman at the desk insists Absolut - the vodka company - has nothing to do with the place, it does have a section where a revolving exhibition displays the Absolut advertising works of Andy Warhol and those who came in his wake for whom art and commerce were interchangeable currencies.
So on any given day the advertising of Keith Haring, Holly Johnson (of Frankie Goes to Hollywood), outsider artist Howard Finster, Ralph Steadman and a number of contemporary Swedish artists are on display.
But the real attractions of the museum are the installations and displays upstairs, where you can walk through Sweden's sometimes troubled encounters with hard liquor.
You may sit in a room designed to replicate a hangover (you need to supply the dry mouth, headache and regret yourself) and can sniff various herbs and ingredients used to give an otherwise bitter, clear and brutally-powerful liquor some semblance of taste.
All this seems rather ambiguous: visitors appear to be counselled about the dangers of over-imbibing, in other places images of drunk people show them having a very good time. A recent exhibition celebrated 150 years of clubbing.
Sweden has a curious relationship with alcohol. It has a highly-regulated system overseeing the production, distribution and sale of alcohol - only low-alcohol beverages in supermarkets - and the liquor shop chain Systembolaget is a government-owned monopoly and isn't allowed to advertise.
The emphasis is on moderation and many Swedes seem happy with low-alcohol options. So maybe that Spritmuseum hangover room is for the curious who are lucky enough never to have had one.
After a pleasant lunch of herring and aquavit downstairs in the Spritmuseum - while looking at the black water of the harbour under a slate grey Stockholm sky - I'll never hear Fairytale of New York in quite the same way again. Skal.
