Wine you may want when it's wet (5)
I believe the answer is:
macon
'wine' is the definition.
(macon is a kind of wine)
'you may want when it's wet' is the wordplay.
I cannot quite understand how this works, but
'when' could be 'on' (I've seen this in other clues) and 'on' is located in the answer.
The remaining letters 'mac' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for macon that I've seen before include "Dry white Burgundy wine" , "French wine region" , "Variety of Burgundy" , "red" , "Burgundian wine" .)
