Today, Riesen is well established in many European and North American markets, such as Germany, Scandinavia, the UK, the United States and Canada. The Riesen brand successfully expanded internationally and was introduced to the United States in 1991. RIESEN's success continued: together, chocolate and the basic idea of an extra long-lasting chewy treat resulted in the RIESEN Chocolate Chew – which became extremely popular. The inimitable, intensively chocolatey taste is due to the special blend of selected Gavoa cocoa beans. Riesen ( / ˈ r iː z n/ ⓘ; German pronunciation: [ˈʁiːzn̩]) ( German for Giants) is a confectionery of chocolate and chocolate-flavored caramel produced and distributed by August Storck KG, a German confectioner that also produces Werther's Original.

Dark chocolate on the outside, rich chocolate caramel on the inside – a particularly long-lasting chewy treat. It contained chopped peanuts in caramel covered in chocolate; however, it was discontinued in 2002 due to poor sales.
