Red Dwarf is beneath me (5)
I believe the answer is:
medoc
'red' is the definition.
(type of red wine)
'dwarf is beneath me' is the wordplay.
'dwarf' becomes 'doc' (dwarf in Disney's Snow White and the Seven Dwarfs).
'is beneath' says to put letters next to each other (in a down clue).
'doc' after 'me' is 'MEDOC'.
(Other definitions for medoc that I've seen before include "that's regularly drunk?" , "Wine-growing area" , "Red wine from southwest France" , "French red wine" , "Type of wine" .)
