unwed

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

'single whiskey' is the definition.
'unwed' can be an answer for 'single' (I've seen this in another clue). I'm unsure of the 'whiskey' bit.

'in france one day' is the wordplay.
'in france' becomes 'un' (I've seen this in other clues).
'one day' becomes 'wed' (abbreviation for Wednesday).
'un'+'wed'='UNWED'

Can you help me to learn more?

(Other definitions for unwed that I've seen before include "Not married" , "Without benefit of clergy?" , "Divorced" , "Single" .)

I've seen this clue in The Times.
