The chap consuming the house wine (5)
I believe the answer is:
macon
'wine' is the definition.
(macon is a kind of wine)
'the chap consuming the house' is the wordplay.
'the chap' becomes 'man' (chap can mean a man).
'consuming' means one lot of letters goes inside another.
'the house' becomes 'co' (I've seen this in other clues).
'man' going around 'co' is 'MACON'.
(Other definitions for macon that I've seen before include "red" , "Wandering (knight)" , "Drink" , "French wine district" , "A heavy Burgundy" .)
