Sour Skittles

Skittles candy products, produced by the Wm. Wrigley Jr. Company, come in a wide variety. Most of the varieties are available only in particular regions of the world. The oldest Skittles product is Original Fruit Skittles, which was originally released in Europe in 1974, and was launched in the United States in 1979. The most recent flavor, Pride Fruits, was released in June 2017. Earlier Skittles products tended to focus on fruit flavors, more recent products have branched out to include flavors such as chocolate, bubble gum, popcorn, mint, and sours. Skittles products also come in a wide variety of colors, although different Skittles products often use the same colors for sweets with different flavors. For example, the color yellow is associated with lemon flavor in Original Fruit Skittles and as banana berry in Tropical Skittles.

The original Skittles in the United States were orange, lemon, lime, grape and strawberry. Skittles no longer has the original Skittles for sale in the United States, although they label the package as if they are original. Skittles lime was changed to green apple.

In Taiwan, South Korea, China, Australia, and, as of 2014, the United States of America Lime is replaced with Green Apple flavor.
Lime was moved to the "Darkside" flavor in 2013. Green Apple also replaced Lime in the United States for a brief time in April 2008, as part of a promotion. In 2013, this change was made permanent.

*Sour Green Apple replaced Sour Lime in the U.S., likely in late 2012.
