A rampant wild boar will find water (5,4)

I believe the answer is:

adams wine

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

'water' is the definition.
(I've seen this before)

'a rampant wild boar will' is the wordplay.
'rampant' is a reversal indicator (rampant can mean rearing).
'wild' becomes 'mad' (similar in meaning).
'boar will' becomes 'swine' (I can't justify this - if you can you should believe this answer much more).
'mad' back-to-front is 'dam'.
'a'+'dam'+'swine'='ADAMS WINE'

'find' is the link.

Can you help me to learn more?

(Another definition for adams wine that I've seen is " water".)

I've seen this clue in The Times and The Sunday Times.
