Friday Flick ... and a Mystery, too!

The good folks at Affligem (hard g) recently sent me an interesting package.  It included a bottle of beer and an embossed goblet--naturally--but also a wee cordial and an odd wooden serving tray.  A visual:

There are two mysteries here: what's the purpose of the cordial glass, and what am I supposed to put in that extra hole next to the bottle?  (You may glean a clue to question #1 here.)  Today's Friday Flick--which I shall embed below the fold to give you a chance to consider these mysteries--answers only one.  I invite your solutions to the unsolved mystery--and I'll even send out a copy of the nationally-touted Beer Tasting Toolkit if someone can convincingly answer it.  Have at it.
