In this third course of the Beer Quality Series on beer freshness, led by distinguished professor Charles Bamforth, Ph.D, you will learn about beer flavor preconceptions, expectations, and causes of flavor instability. You'll also learn about the science of flavor change and the study and process impacts of flavor stability. In addition, you will review light instability and how it can lead to skunking.

There are 4 modules in this course
In this first module, we examine the importance of flavor stability. We do this, in part by reviewing a study asking consumers if they can differentiate between fresh and stale beer and if it matters to them. We'll review how imported and domestic beer flavor is perceived by consumers, discuss the importance of delivering a consistent flavor, and understand how chemical changes affect beer flavor. We'll also go into how flavor changes are assessed.
