JMich: Quaff is the way Vikings are portrayed as drinking beer. Big gulps, with half the beer ending on the face and/or vest.
Chugging usually requires a funnel, or a pitcher of beer. Again, large quantities in too short a time.
Guzzling is more often encounter with cars, as in gas guzzler, but one can be guzzling beer as well.
Sip and swill are more often about wine or other high volume alcohol drinks, since one takes smaller sips.
Imbibe is quite similar to consume, so a bit rarer to find.

Either way, the words are out there. The fact that they ain't used often is a vocabulary problem, not a language one.
