Light Muscat or Chablis bottles (5)
I believe the answer is:
torch
'light' is the definition.
(torch is a kind of light)
'muscat or chablis bottles' is the wordplay.
'bottles' indicates the answer is hidden within the clue (bottling is a kind of containing).
'TORCH' is hidden in the letters of 'muscat or chablis'.
(Other definitions for torch that I've seen before include "Portable lamp; set alight" , "Link" , "Source of light" , "Deliberately set fire to" , "Set fire to - hand-held light" .)
