Lemonade is the name given to either of two main types of lemon-flavoured beverage.
In North America, lemonade is a cold beverage made from freshly-squeezed lemon juice, diluted with water and sweetened with sugar. There are also artificially-flavoured lemonades and lemonade powders, and low-calorie lemonade made with artificial sweeteners such as sodium saccharin or aspartame instead of sugar.
In the British Commonwealth, lemonade is a carbonated lemon-flavoured beverage that Americans would call "lemon-lime" soda. American-style lemonade is known as "lemon squash".
