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 Vanilla
Vanilla Coke was packaged in standard bottles in accordance with appropriate Coca-Cola packaging. For a brief period of time in mid-2003, the bottles that Vanilla Coke came in, which had before said "Vanilla Coke", were changed simply to "V" (which matched Cherry Coke's new labeling showing a picture of a cherry).In late 2002, a sugar-free version, Diet Vanilla Coke, became available. In some countries, including Australia and New Zealand, a similar drink is marketed as "Diet Coke with Vanilla" and in others is known as Coca-Cola light Vanilla (or Vanilla Coke Light) In 2005, the sugar-free product in the United States and Canada became "Diet Coke Vanilla," with more emphasis on the Diet Coke label. All varieties were discontinued in 2005 in the United States, Canada and the United Kingdom. Both varieties are still available in Australia and Hong Kong, Coca-Cola Vanille (translation) is also available in France and Germany. A new Coke Vanilla Zero was introduced in 2007, along with regular Vanilla. Only these two are available in the United States. The company has not announced any plan to resume production of Diet Vanilla Coke. Diet Vanilla Coke is, however, available using a Coca-Cola Freestyle machine. Coca Cola Zero sugar Vanilla will be available in the UK from April 2017 in 1.75L bottles, 330ml cans, 500ml bottles and multipack of cans.
