Joseph Tobotham died after he was hit in the face with a bottle
Mr Robotham was rendered unconscious by the blow, and fell heavily to the floor, banging his head on the ground and fracturing his skull.
After seven-and-a-half hours of deliberations, they have now been told they can return a verdict of 10-2 or 11-1.
Rose was arrested the day after the killing when he was identified on CCTV footage of the incident and later admitted the manslaughter of Mr Robotham.
But he denies murder.
