Craft Beer Science: Chemistry, Brewing, and Sensory Evaluation

Beer is more than just a popular beverage; it is a complex product of precise biochemical reactions, microbiology, and agricultural science. Understanding the science behind brewing elevates your appreciation and gives you the tools to analyze flavor profiles, fermentation, and production methods. This text-based course guides you through the scientific principles of beer production, from the molecular structure of water and barley to the metabolic pathways of yeast and modern quality control standards. In this course, you will: 1. Understand the biochemical roles of water, malt, hops, and yeast in the brewing process. 2. Analyze the fermentation cycle and the metabolic pathways that produce alcohol and flavor compounds. 3. Learn the sensory science of beer evaluation, identifying key aroma compounds and off-flavors. 4. Explore modern sustainable brewing practices and resource management in commercial production. 5. Examine how alcohol affects human physiology, metabolism, and overall health outcomes. 6. Evaluate the chemical reactions during boiling, hopping, and packaging that preserve freshness. You will start with foundational terminology, beer styles, and raw ingredients before progressing to the chemistry of the brewhouse, fermentation dynamics, sensory analysis, and packaging science. This course is designed for beginners, homebrewers, and hospitality professionals, requiring no prior background in chemistry or biology. Begin your journey into the fascinating scientific world of beer today.
