Beer is one of mankind’s oldest beverages. When cereals were first grown for food, thousands of years ago, a fortunate by-product was discovered. When these tasty grains got wet, they would ferment. This process of fermentation had the ability to transform water into a very palatable drink and so the first beer had been discovered. Nowadays we know for a fact that this transformation is not some dark magic but is caused by the presence of wild yeasts in the air. Although Belgium is, without doubt, the world’s beer capital, the great drink was not invented in Belgium. Clay tablets indicate that brewing was a well-respected occupation in what is now Iran more than 7,000 years ago, but it’s thought that beer was already known to the Sumerians and Babylonians some 3,000 years before that. Back then most brewers were even women.
