Beastly blenders of wines (5)
I believe the answer is:
swine
'beastly blenders of wines' is the definition.
I can't judge whether this definition defines the answer.
'of wines' is the wordplay.
'of' is an anagram indicator (the answer comes from or 'of' the letters).
'wines' with letters rearranged gives 'SWINE'.
Can you help me to learn more?
(Other definitions for swine that I've seen before include "Contemptible person; pigs" , "Pig, pigs" , "Pig; unpleasant person" , "cad" , "Nasty people" .)
