'sombre information' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'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' going within 'graves' is 'GRAVE NEWS'.
