Technical Abstract: The National Institutes of Health reports that 1% of the United States population suffers from celiac disease, an immune reaction to gluten proteins found in wheat, rye, and barley. There is a limited market of gluten-free products for celiac patients to consume. One product frequently demanded by persons with celiac disease is gluten-free beer. The objective of this study was to produce a gluten-free beer that would be acceptable to both persons with celiac disease and the general population. Sorghum syrup formulations were used to create several different gluten-free beers to evaluate ingredient functionality in gluten-free beer. The different formulas were compared against each other and current gluten-free beers on the market. The beers were brewed, fermented, and bottle-conditioned. Each beer was evaluated throughout the process. Physical and chemical tests were used to evaluate the beer include Brix, color, specific gravity, viscosity, and pH measurements were taken. A sensory panel evaluated the beers on flavor, color, mouth feel and overall acceptability. The experimental beers had a Brix measurement that ranged from 5.0 to 6.2 compared to the commercial beers which averaged 6.1. Color ranged from 3-5°SRM for the experimental beers, and 7 to 8°SRM for the commercial beers. The specific gravity showed decreasing trend for all experimental beers (3.0% decrease). The commercial beers had an average pH of 4.61 and the experimental beers average pH was 4.81. The sensory panel indicated that there is a potential for gluten-free beers for the general population but that additional work needs to be completed.
