Abstract: | The history of beer: from a staple food to a consumer product with an enormous variety of styles and tastes. Subject Categories: Biotechnology & Synthetic Biology, History & Philosophy of ScienceAs far back as we can retrace history, beer has always been an important part of human life: it was and still is a valuable food staple that has been constantly improved and adapted to human needs. For most of the time, intoxication was not the main purpose and could only be achieved to a limited extent, if at all, given that beer had a low alcohol content for most of human history. Instead, beer, owing to its specific ingredients and characteristics—alcohol, carbon dioxide and a low pH value—was often the only safe liquid to drink when clean water was rare.For most of the time, intoxication was not the main purpose and could only be achieved to a limited extent, if at all, given that beer had a low alcohol content for most of human history. In addition, beer and other fermented foods are an important source of essential vitamins, such as vitamin B or riboflavin, trace elements and other health‐promoting ingredients. Especially for poorer people who mainly lived on bread or porridge, supplementing their diet with beer was beneficial to their health. Beer was also an important staple for certain professions, such as seafarers, who had to live of vitamin‐poor foodstuffs for longer times. Not surprisingly, many seafaring nations contributed to the spread and improvement of beer brewing (Fig ).Open in a separate windowBeer brewing over timeThe most important discoveries and developments during a history of 10,000 years of brewing beer. |
