Soft drinks, also known as soda pop or simply pop, are non-alcoholic beverages that typically contain water, sweeteners and flavorings. Soft drinks come in a variety of flavors beyond the classic cola, including citrus flavors like lemon-lime and orange, various fruit flavors and specialty flavors like ginger ale, root beer and cream soda. They are generally carbonated through the addition of carbon dioxide, giving them effervescence, a slightly sting tongue sensation and a refreshing crispness. Soft drinks are highly sweetened, usually through the use of high fructose corn syrup, cane sugar or other caloric sweeteners.
