The Primary Sweetener in Australian Coca-Cola Classic
For decades, Coca-Cola Classic in Australia has relied exclusively on sugar, which is derived from cane sugar, as its primary sweetener. This contrasts sharply with the recipe used in the United States, where high-fructose corn syrup is the standard. The choice of sweetener is influenced by regional economics and agricultural factors; the US has a high supply of corn, while Australia has a robust cane sugar industry.
This distinction is not just a technicality; it has a noticeable impact on the beverage's flavour profile. Many enthusiasts claim that Coke made with cane sugar offers a crisper, cleaner taste, and a less syrupy mouthfeel than its HFCS-sweetened American counterpart. While the difference is subtle, it is significant enough for many consumers to express a preference for either the Australian or Mexican version of Coke, both of which use cane sugar.
The Sweeteners in Australian Sugar-Free Options
For those seeking the classic Coke taste without the sugar, the brand offers zero-calorie alternatives, which use intense artificial sweeteners. On its Australian website, Coca-Cola confirms that its no-sugar varieties are sweetened with a blend of specific ingredients.
Sweeteners in Coke Zero Sugar and Diet Coke
- Aspartame (951): This artificial sweetener is a staple in many diet beverages worldwide. It is about 200 times sweeter than sugar and is made by combining two amino acids, aspartic acid and phenylalanine. Because it contains phenylalanine, products with aspartame are required to carry a warning for individuals with phenylketonuria (PKU), a rare genetic disorder.
- Acesulphame Potassium (Acesulphame-K or 950): Often used in conjunction with aspartame, this sweetener is also around 200 times sweeter than sugar. The combination of aspartame and acesulphame-K creates a synergistic effect, enhancing the sweetness and providing a taste closer to that of regular sugar.
These formulations allow Coca-Cola to deliver a zero-sugar, zero-calorie product that mimics the sweetness of cane sugar without the kilojoules. The taste profile for Coke Zero Sugar is specifically formulated to be closer to that of Classic Coke, while Diet Coke has its own distinct flavour.

Why the Different Sweeteners Exist
The use of different sweeteners serves both economic and marketing purposes. For decades, the US has used HFCS because it was a cheaper alternative to cane sugar due to government subsidies. In contrast, Australia's strong domestic cane sugar industry has made it the logical and economically sound choice for the local production of classic Coke. For sugar-free versions, the goal is to provide a guilt-free option for health-conscious consumers or those with specific dietary needs, such as diabetics. The use of intense artificial sweeteners allows for a sweet taste without the caloric load of sugar.
Sweeteners and the Australian Consumer
In Australia, as with many other markets, there has been a growing demand for low-sugar and no-sugar options. Coca-Cola has responded to this trend by expanding its portfolio of low and no-calorie drinks, including Coke Zero Sugar and Diet Coke, which are clearly labelled and marketed. In the past, the company also offered a mid-calorie cola called Coca-Cola Life, which used a blend of sugar and stevia (960), but this product was eventually discontinued in Australia. The move reflected a refinement in the company's strategy to focus on its most popular sugar-free offerings. Consumers can confidently check the ingredients list on any Coca-Cola product to determine the exact sweeteners used.
Conclusion
In summary, the question of what sweetener is in Coke in Australia has a two-part answer depending on the product line. Coca-Cola Classic in Australia is sweetened with cane sugar, which contributes to its unique flavour profile and distinguishes it from the high-fructose corn syrup version found in the US. The zero-sugar varieties, such as Coke Zero Sugar and Diet Coke, are sweetened with a blend of artificial sweeteners, including Aspartame (951) and Acesulphame Potassium (950). This tiered approach ensures that Coca-Cola can cater to a diverse range of consumer tastes and dietary preferences across the Australian market.
