Part three of the series will include basic chemistry techniques and some more advanced instrumentation used in the beer quality lab. We will discuss standard methods of the American Society of Brewing Chemists (ASBC) and the importance of standardization and repeatability. Participants will perform analyses including bitterness units, alcohol content, density, CO2 volumes, dissolved oxygen, and total package oxygen. Lab activities will involve an Anton Paar packaged beverage analyzer, UV/Vis spectrophotometer, Zahm & Nagel air tester, and mini gas chromatography system.
