Lemonade is a fruit-flavoured drink made from water. Lemonade usually contains carbon dioxide, which is responsible for the small bubbles. The most common types of lemonade are orange and lemon. But there are also lemonades made from other fruits, such as strawberries, limes or passion fruit. Cola and energy drinks are also a type of lemonade.
Soft drinks like lemonade have been around since ancient times. In the Roman Empire, there was a drink called posca. It consisted of water with vinegar mixed in. Posca was still very popular many centuries later. It is not known exactly when the current form of lemonade was created.
Lemonade is usually made from a syrup on which water is poured. When the syrup mixes with the water, the lemonade is created. The syrup usually consists of pieces or juice of the fruit that the lemonade is supposed to taste like. It also often contains sugar, citric acid and carbon dioxide. Sometimes colouring agents are also mixed into the syrup. In cola, the syrup consists of flavouring from the kola nut, which contains caffeine. In addition, cola syrup usually contains phosphoric acid, a chemical that enhances the flavour.
