Beer
Beer was initially invented during the Agricultural Revolution, as a byproduct of fermenting wheat in water. It soon became a popular drink with wealthy families, but became popular among commoners as well because it was so easy to produce. Beer is associated with prosperity and happiness.
Wine
Wine was developed soon after beer, and rose to prominence during the reign of the Ancient Greeks. It continued to be popular in the Roman Empire, and the area is still well known for its numerous varieties of wine and grapes.
Rum
Rum was initially used as a way to keep sailors from getting thirsty on long ocean trips, particularly when international trading began to grow. Rum was commonly traded with Africans for American and Spanish slaves, and could have sparked the American Revolution when Britain raised taxes on its primary ingredients.
Coffee
Coffee was initially produced in Western Europe, and soon coffeehouses could be seen across Britain and France. Although it later became one of the most popular American drinks, it was created in Europe. During the American Revolution, there were numerous American coffeehouses, where men gathered in the morning, and, excited by caffeine, began to orally disdain their horrible British overlords.
Tea
Tea was originally created in China, and the British quickly began trading to obtain the valuable drink. Tea played a role in why the British colonized India, as well as for the spices that can be used alongside tea. Tea became a drink synonymous with Britain, with some meals and/or snacks being simply referred to as "Tea".
Coca-Cola
Coke was initially created for medicinal purposes and contained the drug cocaine. Once people realized how good it tasted, it became a pop-culture icon from its countless advertisements that were seemingly everywhere. The spread of the drink internationally shows the influence of America on the global culture.
