Caffeine-Free Pepsi is a version of the cola Pepsi that omits the caffeine that is customarily part of a cola. It was introduced, under the brand namePepsi Free, in 1982 by PepsiCo as the first major-brand caffeine-free cola sold in years. A sugar-free variant, originally known as Diet Pepsi Free, was also introduced. The "Pepsi Free" name itself was phased out in 1987, and today these colas are known simply as Caffeine-Free Pepsi and Caffeine-Free Diet Pepsi.
Background
When it was first introduced, Caffeine-Free Pepsi's label background was red, but to avoid any confusion with Coca-Cola, the background color was changed to gold in 1987. As part of Pepsi's changing their background to blue in 1998, Pepsi Caffeine Free's background changed to blue with the letters outlined in gold. In 2008, the caffeine-free version reverted to a gold background. Caffeine-Free Coca-Cola labels also have a gold background. The logo letters are bordered in red for the regular variety, in the case of the diet variety, they are entirely red in color.
Two cans of Pepsi Free are seen, at separate times, in the 1983 filmMr. Mom. Two-liter bottles and 6-packs of cans of Pepsi Free appear in a refrigerator case behind Sylvester Stallone’s character in the grocery store scene in the 1986 filmCobra. Pepsi Free was the subject of a scene in the 1985 filmBack to the Future. Upon entering a café in 1955, Marty McFly asks for a Tab and is told that he cannot have a "tab," unless he orders something. He then asks for a Pepsi Free and is told, "If you want a Pepsi, pal, you're gonna pay for it!" Finally, he asks for "something without any sugar in it," and is served black coffee. A can of Diet Pepsi Free can be seen beside Marty's alarm clock towards the beginning of the movie when Doccalls him to remind him to meet him at the mall. The can is also seen toward the end of the movie when Martywakes up in the morning at his house in 1985. When introduced, Pepsi Free was available in cans, 2 liter bottles, and 20 ounce glass bottles. Caffeine-Free Pepsi is currently available in cans, 16 oz. plastic bottles and 2 liters, though availability varies from store to store.
