History.
Pepsi was first introduced as "Brad's Drink" in New Bern, North Carolina, United States, in 1893 by Caleb Bradham, who made it at his drugstore where the drink was sold. It was renamed Pepsi-Cola in 1898 after the
—a blend of kola nut extract, vanilla, and "rare oils"—for what was initially known as "Brad's Drink," but on August 28, 1898 was renamed Pepsi-Cola. Bradham named his drink after a combination of the terms “pepsin” and “cola,” as he believed that his drink aided digestion much like the pepsin enzyme does, even though it was not used as an ingredient. His assistant James Henry King was the first to taste the new drink.
