Making a drink can happen in many ways. 

History shows that people have enjoyed drinks for a long time. 

There are many specific facts about different drinks. 
Drinking connects to many parts of our daily lives. In ancient Greece, people held social gatherings called symposia. In ancient Rome, they held gatherings called convivium. Some people use a "loving cup" to share a drink at weddings. This is a large cup that everyone shares until it is empty. Toasting is another way to honor a person. These traditions show how much people value sharing a drink.
A drink, or beverage, is any liquid intended for human consumption. While the most basic function of a drink is to satisfy thirst, beverages play massive roles in human culture. Water is the most consumed liquid on Earth. Tea is the second most consumed drink in the world, following only water. 
Thirst is a biological signal regulated by the hypothalamus. This part of the brain responds to changes in blood volume and electrolyte levels. When the body becomes dehydrated, it creates an instinctive craving for fluids. Water is essential for life, but complete deprivation of water results in death faster than almost any other substance besides oxygen. 
Humans use several different methods to prepare and process beverages. To make juice, people use crushing or pressing. For example, basket presses were developed in the Middle Ages for winemaking. 

Other processes involve chemical or biological changes. Fermentation is a metabolic process that converts sugar into ethanol. This has been used since the Neolithic age to create alcoholic drinks. In winemaking, yeast is added to grape juice in an anaerobic environment. For beer, brewers use water, grain, yeast, and hops. They use malting to germinate grain and mashing to create sugars. 
History shows that beverages have shaped human civilization. Archaeological evidence suggests wine production existed in Georgia and Iran long ago. Beer may have been known in Neolithic Europe by 3000 BCE. Some argue the invention of beer helped humanity develop technology and build societies. 
Specific drink types have unique production requirements. Coffee comes from the roasted seeds of evergreen shrubs, mainly *Coffea arabica* and *Coffea canephora*. These plants are grown in over 70 countries. Milk is a primary source of nutrition for babies. In many cultures, humans continue to consume dairy from cattle, goats, or sheep. 
Beverages also serve as central tools for social connection. In ancient Greece, people held symposia to drink watered-down wine and hold discussions. Ancient Romans practiced similar social gatherings called convivium. Many traditions involve shared rituals. Toasting is a way to honor a person or wish them goodwill. The "loving cup" is a large vessel shared by a group at weddings or celebrations. Even religious history is tied to drinks. In East Africa and Yemen, coffee was used in religious ceremonies. Some religions also forbid or restrict alcohol for various reasons.
