Glasses upset — ten Grolsch bottles overturned (9)
I believe the answer is:
lorgnette
'glasses' is the definition.
(lorgnette is a pair of glasses with a handle)
'upset ten grolsch bottles overturned' is the wordplay.
'bottles' says the answer is hidden in the clue (bottling is a kind of containing).
'overturned' shows that the letters should be reversed in order.
'ettengrol' is hidden within 'upset ten grolsch'.
'ettengrol' written backwards gives 'LORGNETTE'.
(Other definitions for lorgnette that I've seen before include "Eyeglasses with a long handle" , "Device helping to read" , "Opera glass" , "Pair of spectacles on a stick" , "Handle-mounted glasses" .)
