Coca-Cola has vowed to retain a strong presence in South Australia despite closing its bottling line in Adelaide, and they end 66 years of local production.

The line will produce its final bottle of Coke on Tuesday. General Manager Mr. Mortimer said after 66 years and around 10 billion bottles produced, it's time for this plant to retire.

The decision to close the Adelaide bottling line came after a national review that recommended boosting production in Queensland and Western Australia but winding it down in SA.
