The goal of this project was to craft a pleasant tasting non-alcoholic beer from Wachusett’s Green Monsta IPA. Experiments were developed for ethanol absorption that utilized the techniques of an oil layer, freezing, and heating. Results showed use of castor oil, corn oil, and coconut oil as a boundary layer have promise, but require further stimuli to lower ABV beyond 4%. Freezing was successful in removing adequate ethanol to form a NA beer, but the quantity produced from this technique was insufficient to be deemed feasible. Heated trials showed a continued downward trend in ABV, but exhibited degradation in color and aroma. Future research is to be guided towards the effect of pressure and chemical oil composition.
