Correctional Services said that “matters are under control” at Johannesburg’s Sun City Prison on Wed.
Janine van Stolk of SAB said there was a radical shift in the industry when Amstel terminated its contract with them.
She said the shift was created despite SAB having three companies that supply them with bottles.
Van Stolk said there has also been a significant growth in the market and demand exceeded supply.
"It is not that the supply was not enough, but demand grew faster than expected, and this created the problem that we find ourselves in today."
She said people should remember that beer was not only about the content in the bottle but the bottle itself.
