"SAB confirmed that its soft drinks division would in all probability be facing intermittent product shortages due to CO2 supply issues," the company said in a statement.
The company uses the carbon dioxide for carbonation. The shortage follows the unplanned shutdown of PetroSA's Mosel Bay refinery.
SABMiller is the world's third-largest brewer and the country's biggest producer of soft drinks.
"The soft drinks division is prioritising its key packs during this period while it continues to investigate aletrnative supplies of CO2 to ensure availability of its products," the company said.
