Stumbling, otherwise, around bar (5)
I believe the answer is:
ingot
'bar' is the definition.
(block of metal, eg a bar of gold)
'stumbling otherwise around' is the wordplay.
'around' says the answer is hidden in the clue.
'INGOT' can be found hidden inside 'stumbling otherwise'.
(Other definitions for ingot that I've seen before include "this must be cast" , "Block of, eg, gold" , "Form of gold or silver" , "Block of precious metal" , "Piece of cast metal" .)
