A soft drink is a beverage that does not contain alcohol; generally it is also implied that the drink does not contain milk or other dairy products and that it is consumed while cold. Carbonated soft drinks are commonly known as soda, soda pop, pop, coke, cola or tonic in various parts of the United States, pop in Canada, cooldrink, colddrink, fizzy drink or soft drink(formal) in South Africa, fizzy drinks, pop or soft drinks in the United Kingdom and Australia and sometimes minerals in Ireland. The adjective soft specifies a lack of alcohol by way of contrast to the term "hard drink". The word drink, while nominally neutral, sometimes carries connotations of alcoholic content. Beverages like colas, flavored water, sparkling water, iced tea, sweet tea, lemonade, squash, and fruit punch are among the most common types of soft drinks, while hot chocolate, hot tea, coffee, milk, tap water, juice and milkshakes do not fall into this classification. Many carbonated soft drinks are optionally available in versions sweetened with sugars or with non-caloric sweeteners.
