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.
Coca-Cola with Lemon
Coca-Cola with Lemon is a soft drink brand owned by The Coca-Cola Company, launched to compete with Pepsi Twist. It is produced and distributed by The Coca-Cola Company's bottlers. Diet Coke with Lemon was introduced in the United States in 2001 and is still available as a semi-sugar free version in Coca-Cola Freestyle machines.
