Beer in Egypt has long held a significant role, and its presence in the country is thought to date back to the Predynastic period. In ancient Egypt wine was preferred by the upper class, whereas beer was a staple for working class Egyptians and a central part of their diet. Despite religious restrictions and conflicting views on alcohol after the Muslim conquest of Egypt, the consumption of beer did not cease, and it still remains the most popular alcoholic beverage in the country by far, accounting for 54 percent of all alcohol consumption.
