I've taken Organic I, II, Organic lab, Polymer Chemistry, P-Chem, Analytical Chem, Qualitative Analysis, Chemical & Material Balances, two Thermo classes, Environmental Modeling, Unit Operations and Processes in Env. Engineering among others, and I can safely say, none of those have helped me brew better beer.
Maybe I take for granted understanding the fundamentals of water chemistry and fermentation, but honestly, brewing beer is how you get better at brewing beer. If you want to read up on the science of brewing, look up scholarly articles on brewing. They're really out there believe it or not, and a whole lot more related to what we're interested in rather than being able to interpret a P-V phase diagram or the kinetics of the elimination rxn of 1,2-dibromo-1,2-diphenylethane and the resultant conformation.
