Tap it

ALE

Think of a frothy beverage often served on draft at a pub, especially one that’s not a lager.

Tap it" is a playful hint pointing to "ALE" because ale is traditionally served from a tap in pubs. The word "tap" here works as both a verb (like tapping a keg) and a noun (the spout itself), making it a clever double-meaning clue. It’s a common crossword trick where the surface meaning misleads slightly until you think of the drinking context.
