Latent flaws and contaminations, undetectable by most sensory and 
chemical-based quality control programs, pose a risk to breweries—how 
can you detect and fix the cause of a flaw that has not yet developed? 
In this research, we present a novel approach to predicting latent flaws
 and tracing their creation back to the root cause in the beer brewing 
process. Furthermore, we show that the process may be able to predict 
flaws that occur in beer after packaging and distribution, increasing 
the actionability of any quality control program. At Analytical Flavor 
Systems, machine learning and artificial intelligence are used to build 
quality-control and flavor-profiling tools for the food and beverage 
industries. By applying our algorithms to production data and human 
sensory data collected with the Gastrograph review application, 
predictions can be made as to the likelihood of a flaw appearing and how
 to prevent, delay, or mitigate these flaws.
Zachary Bushman is a chemist at Analytical Flavor Systems and an 
avid home brewer. He received his B.S. degree in chemistry from the 
University of Wisconsin-Platteville in 2013. In 2015, he began working 
at Analytical Flavor Systems (AFS) in State College, PA. AFS is a 
company dedicated to flavor profiling and quality control in the craft 
beverage industry. He is now the head chemist at AFS and directs 
projects on flaw detection and hardware development.
