Scholarship on brewing in early modern London is torn between two irreconcilable stories, one positing stunning growth before 1560 and the other insignificant change until after 1720. Careful attention to company and court records as well as state papers, however, reveals that by 1600 London brewing had boomed, likely making it Europe’s largest brewing centre, led by individual houses operating on scales close to the largest of the mid-eighteenth century. Such breweries were accurately perceived to be large scale and highly profitable, clustered along the Thames in urban industrial zones.
