Diet Coke
Diet Coke does not use a modified form of the Coca-Cola recipe, but instead an entirely different formula. The controversial New Coke, introduced in 1985, used a version of the Diet Coke recipe that contained high fructose corn syrup and had a slightly different balance of ingredients. In 2004, Coca-Cola introduced Coca-Cola C2, which it claims tastes much closer to Coca-Cola but contains half the carbohydrates. In 2005, the company introduced Coca-Cola Zero (replaced by "Coca-Cola Zero Sugar" in 2017), a sugar-free variation of regular Coca-Cola.
Steaz
Steaz products have met with generally positive reception. For instance, FastCompany and Greenopia have considered Steaz to be one of the most eco-friendly beverages available. Formal reviews of their individual products have generally been positive, although some have noted that Steaz products have similar caloric and sugar content per serving compared to traditional soft drinks such as Coke.
