'sombre information' is the definition.
I know nothing about this answer so I can't tell whether this works.

'about the young french wine' is the wordplay.
'about' indicates putting letters inside.
'the young' becomes 'new' (I've seen this in another clue).
'french wine' becomes 'Graves' (wine from the Graves region in France).
'new' put within 'graves' is 'GRAVE NEWS'.
