The Hershey's chocolate bar (usually called a "Hershey bar") is a flagship chocolate bar described as "The Great American Chocolate Bar" manufactured by the Hershey Company. Hershey Milk Chocolate and Milk Chocolate with almonds and peanuts were both introduced in 1900. A circular version of the milk chocolate bar called Hershey's Drops was released in 2010.
Hershey process milk chocolate is cheaper to make than other types of chocolate as it is less sensitive to the freshness of the milk. The process is a trade secret, but experts speculate that the milk is partially lipolyzed, producing butyric acid, which stabilizes the milk from further fermentation. This compound gives the product a particular sour, "tangy" taste, to which the US public has become accustomed, to the point that other manufacturers often add butyric acid to their milk chocolates.
Hershey bars are available in a variety flavors: Milk Chocolate, Milk Chocolate with Almonds, Special Dark Chocolate, Cookies 'N' Creme, Symphony, Mr. Goodbar, and Krackel. There were also six limited flavors: Double Chocolate, Nut Lovers, Twosomes Reese's Pieces, Cookies 'N' Chocolate, Twosomes Heath, and Twosomes Whoppers. All flavors
