'famous red' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'clarets spilt drunk by dog' is the wordplay.
'spilt' indicates anagramming the letters.
'drunk by' means one lot of letters goes inside another.
'dog' becomes 'fido' (I've seen this before).
'clarets' is an anagram of 'elcastr'.
'elcastr' placed into 'fido' is 'FIDEL CASTRO'.
