Skittles, a brand name of candy products produced by the Wm. Company, come in a wide variety of flavors. Most of the varieties blueberry and blackcurrant available only in particular regions of the world. The first flavor was Original Fruit Skittles, first released in Europe in 1974, and then in the United States in 1979.
In 2013, Skittles changed its original flavor line-up to include green apple, causing a consumer backlash. Green apple also replaced lime in the sour packets. In Europe and Australia, purple Skittles are blackcurrant flavored. Blue-colored cherry cola flavored skittles were included in a limited edition variant in 2015.
In the United States and other countries excluding Europe and Australia, green Skittles were green apple flavored from 2013 until 2021. Green apple also replaced lime in the United States for a brief time in April 2001, as part of a promotion. In 2021, it was announced that, due to public demand, this change would be permanently reversed, bringing the lime flavor back to the original mix of Skittles for the first time since 2013. Tropical Skittles have two flavors in one Skittle.
