Description
Small breweries have become a growing trend in the Pacific Northwest, as well as nationwide. Many microbreweries lack the advantages large breweries have (time, space, and money) when it comes to testing their beer in regards to quality analysis and control. The objectives of this study were to modify and develop QA/QC protocols from the American Society of Brewing Chemists Methods for Craft Breweries (ASBC) for use in classrooms or small breweries. This work focused on revising methods for international bitterness units (IBU), alcohol by volume (ABV), and standard reference method (SRM) for beer. Samples were donated from local breweries and analyzed using the standard operating procedures (SOP) developed in the study. Instrumentation included UV-Vis spectroscopy and gas chromatography with a flame ionization detector.
