The maker's page gives the same list word for word as usda-2025 plus the phenylketonurics warning, so the normalised rows stay on usda-2025. It covers Diet Coke in every size ("Available Sizes: 7.5 fl oz, 8 fl oz, 12 fl oz, 13.2 fl oz, 16.9 fl oz, 20 fl oz, 1.25 Liters, 2 Liters") and prints "Caffeine Content: 46mg / 12 fl oz"

About this product
Diet Coke 20 fl oz is the single 591 ml PET contour bottle of Diet Coke sold in the United States, The Coca-Cola Company's sugar-free cola.[2][3] The front label reads "NO SUGAR NO CALORIES" and carries a "0 CALORIES PER BOTTLE" badge.[4] It is sweetened with aspartame, preserved with potassium benzoate "to protect taste" and caffeinated, and the maker gives 46 mg of caffeine per 12 fl oz, with a warning for phenylketonurics that it contains phenylalanine.[3] Coca-Cola US lists 20 fl oz among eight Diet Coke sizes, from a 7.5 fl oz can to a 2 litre bottle.[3] Two New England stores, Klem's in Spencer, Massachusetts and Percy's Hardware in Litchfield, Maine, sell the bottle under this UPC for USD 2.39 to 2.99.[1][5]
Diet Coke launched in 1982; Coca-Cola US distinguishes it from Coca-Cola Zero Sugar, launched as Coca-Cola Zero in 2005, by its lighter taste.[3]
