passport

I'm a little stuck... Click here to teach me more about this clue!

'that's commonly exhibited at the airport' is the definition.
(a passport is shown at the airport)

'hand round alcohol' is the wordplay.
'hand round' becomes 'pass' (synonyms. I am not sure about the 'round' bit.).
'alcohol' becomes 'port' (port is a type of wine).
'pass'+'port'='PASSPORT'

Can you help me to learn more?
