All Bundaberg Brewed Drinks naturally brewed products contain minute residual traces of alcohol. Our manufacturing process uses natural yeast which feed on sugars and ferments the 'brew' to be used as a base for our beverages. Alcohol is a by-product of this fermentation process. Before we fill the product into bottles we heat the brew to above 70 degrees C. to kill the yeast, halt the fermentation process, and remove the alcohol. After this heating process all of our products have a residual alcohol level of less than 0.5%... The legal level allowable in a soft drink for it to be labelled as a non alcoholic beverage is 0.5%.
