A detailed study traces beer's development from ancient brewing practices to modern commercial production, interweaving historical anecdotes, portraits of notable brewers, and descriptions of early and contemporary breweries. It explains brewing methods and the evolution of ale, porter, and lager, and presents economic analyses of the beer trade, consumption statistics, and industry tables. The author examines beer's social and sanitary claims, contrasts fermented beverages with distilled spirits, and argues that beer can mitigate intemperance. Chapters assess agricultural ties, effects of prohibitory laws, and policy debates, while appendices supply quantitative production figures, chemical analyses, illustrations, and a directory of brewers.
