Beer brewing is an ancient practice that dates back to at least the 5th millennium BC. The first recorded mention of beer comes from Mesopotamia, where it was brewed with barley and other grains. The earliest beers were probably quite simple, and most likely resembled modern-day gruits.
Throughout the centuries, beer brewing evolved and became more sophisticated. New ingredients and methods were introduced, and beer became an important part of many cultures. In the medieval period, monasteries played a significant role in the development of beer brewing, as they produced large quantities of beer for both religious purposes and sale. Today, there are thousands of different brewers around the world, making a huge variety of beer styles.
