Try small drink producing gas (6)
I believe the answer is:
gossip
'gas' is the definition.
(I've seen this before)
'try small drink' is the wordplay.
'try' becomes 'go' (both can mean an attempt).
'small' becomes 's' (abbreviation - e.g. clothes size).
'drink' becomes 'sip' (sipping is a kind of drinking).
'go'+'s'+'sip'='GOSSIP'
'producing' is the link.
(Other definitions for gossip that I've seen before include "Chin-wag, chit-chat" , "Rabbit" , "Natter" , "Idle chat, tattle" , "Idle and mildly malicious talk" .)
