Why did German-style lagers become widespread in the Americas?

German-style lagers became widespread in the Americas primarily due to the advancement of industrial technology and the adoption of standardized brewing practices. While traditional brewing was once limited by seasonal temperature constraints, the development of refrigeration and ice-making equipment in the late 19th century allowed brewers to produce lager beer year-round.12

Furthermore, the industry benefited from the implementation of pure-culture technology. By utilizing pure yeast cultures—a practice quickly adopted by Continental lager brewers—producers were able to achieve greater consistency in their products. Following the repeal of Prohibition in 1933, larger breweries that had survived the era were well-positioned to dominate the market. These major corporations focused on producing consistent, mild, and light-coloured lagers, which eventually led to their overwhelming dominance of the commercial beer industry by the mid-20th century.234
