Morphology
The meaning 'to begin serving beer by opening a keg' follows directly from combining 'tap' (make an opening to draw out liquid) with 'keg' (a small barrel): the action is literally to make an opening in the barrel to draw drink. This simple verb+object compositional pattern is common and predictable, so a B1 learner who knows the constituent words would readily infer the MWE meaning.
Etymology
Tap the keg comes from the real action of putting a tap into a full keg so beer flows out. So when someone says tap the keg, it means 'to begin serving beer' at a party.
