The book “Beer in the Middle Ages” is dedicated to the history and development of brewing in medieval and Renaissance Europe. During the era of fierce wars and crusades, beer was a part of everyday life and a drink for people of all ages and social groups: it was drunk at almost any time of the day or night. In early modern times, the foamy drink, which was first brewed at home, became an export product and came under the protection of the state. European kings and lords tried in every possible way to control the beer trade, and ordinary people tried to make money from the preparation and sale of the intoxicating drink. Surprisingly, monasteries played a special role in the development of medieval brewing: thanks to the use of high-quality equipment that was not available to poor residents of villages and cities, the monks managed to significantly develop the brewing industry. It is not for nothing that St. Patrick, the Baptist of Ireland, had a personal priest-brewer. The publication will be of interest to historians, cultural experts, as well as a wide range of readers interested in the Middle Ages. The publishing design is preserved in PDF A4 format.
