Even though both Diet Coke and Coke Zero appear to be the same in terms of not having sugar and calories, there is a lot of difference between them. They have a different chemical composition which makes them differ in taste. Even in terms of branding, they cater to different target audience. However, for the common man, these both terms are much same and hence it is very important to clear the difference between these both.
With the massive promotion and branding, the Diet Coke has become very popular even since it was launched in 1982. During this period, many people became health conscious and started to worry about the calorie content of these drinks. Coca-Cola launched the Diet Coke for people who are conscious about their weight. It became very popular with women for its low-calorie content. Diet Coke has 338 and 330 citric acids. It has a caffeine content of 12.8 mg per 100 ml. Diet Coke is sweetened with aspartame. The taste of the Diet Coke has attracted a lot of soft drink lovers.
Coke Zero was launched much later in the year 2005. This was aimed at the male audience as men did not show much interest in Diet Coke. Coke Zero has a caffeine content of 9.6 mg per 100 ml. Coke Zero tastes similar to the regular coke and has 338 and 331 sodium citrate. Coke Zero is sweetened with a blend of low-calorie sweeteners. With the help of the Coke Zero, the users who were not much keen to taste the Diet Coke also got an option of a low-calorie soft drink.
These are some of the differences between Diet Coke and Coke Zero. Coca-Cola wants to capture the market segment by promoting similar products aimed at a different section of the audience. While Men prefer Coke Zero for its familiar taste, women are likely to go for Diet Coke.
