Abstract

Financial incentives from the state and wider distribution potential have lured many west coast brewers to open satellite breweries in Virginia. Quality control is crucial for any brewery and especially important in satellite breweries that need to imitate the standard set by the parent brewery. Zinc, magnesium, iron, sodium manganese, and calcium are trace elements found in wort and are essential for enzymes that catalyze fermentation reactions. These elements protect against cell stress, play a crucial role in flocculation, and can affect the flavoring and coloration of beer. Barley, water, and hops are the sources of these elements in beer. We propose that the concentrations of these elements in beer manufactured in California and its satellite locations in Virginia will be the same. We have acquired two sets of beer samples - one manufactured in California and one in Virginia - from Stone Brewing and Ballast Point Brewing Company respectively. Microwave Plasma Atomic Emission Spectrometer (MP-AES) is an atomic emission technique which quantifies the concentration of an element in a sample by comparing its emission to that of known concentrations of the element. MP-AES along with a multi-elemental calibration standard shall be used to quantitate the elements in the beer samples. The beer elemental concentrations shall be reported upon conclusion of this study.
