The document provides a comprehensive overview of pasteurization in small breweries, focusing on its historical context, mechanisms, and critical role in microbial control. It distinguishes pasteurization from sterilization and elaborates on the use of tunnel pasteurizers to manage time and temperature effectively. The Pasteurization Project is highlighted, addressing challenges such as temperature stratification and flavor profile alterations in beer. Experimental trials, including sensory testing and laboratory analyses, demonstrate successful microbial reduction and preferences for pasteurized beer, with plans for ongoing research.
