The goal of this project was to determine the effects of dissolved oxygen (DO) and other phenomena on the shelf-life of Purgatory Beer Company's Two-Car Garage Double IPA, maintained at two separate storage temperatures. Indigo carmine titration and oxygen analyzing equipment were used to identify the changing profile of DO, while sensory analysis and Fourier-transform infrared spectroscopy were used to measure variations in physical qualities and chemical composition. Data from these tests indicate that the DO reactions were most likely diffusion-limited. Recommendations of a 7-week shelf-life and refrigerated storage were made to Purgatory Beer Company after analysis.
