Maybe hunting family with small wine (10)
I believe the answer is:
bloodsport
'maybe hunting' is the definition.
I can't judge whether this defines the answer.
'family with small wine' is the wordplay.
'family' becomes 'blood' (blood can mean one's family).
'with' is a charade indicator (letters next to each other).
'small' becomes 's' (abbreviation - e.g. clothes size).
'wine' becomes 'port' (port is a kind of wine).
'blood'+'s'+'port'='BLOODSPORT'
Can you help me to learn more?
(Other definitions for bloodsport that I've seen before include "bullfighting, perhaps" , "Perhaps hunting" .)
