While fruit is a common ingredient in beer, our research takes a unique approach by studying the effects of pomegranate juice (PJ) on the physicochemical and nutraceutical characteristics of craft fruit beer. These properties have been studied in PJ and other beverages using pomegranate; however, there is insufficient information on fruit beer. PJ, known for its health benefits, was obtained by compressing the fruit in a manual press and characterizing it. The base beer, a blonde ale with two hops, Cascade (C) and Saaz (S), was used. PJ was added to the beer during the second and third fermentation steps. Beer quality was analyzed using ASBC methods: phenolic compounds, sugars, and ethanol content by HPLC, and antioxidant capacity by ORAC. PJ presented a pH of 3.8 and 14°Brix. The beer evaluated was the third fermentation beer called 3FC and 3FS; due to the type of hops used, in general, 3FS presented better physicochemical characteristics; the relevant result was alcohol content around 6.0%, but ethanol content by HPLC was 7.36% for 3FS and 7.19% for 3FC. PJ in phenolic compounds provides the beer with 4-hydroxybenzoic acid, epicatechin, and synaptic acid. However, the hop used influenced the phenolic profile of each beer. The antioxidant capacity of 3FC was higher at 19.75 mm ET/L. In conclusion, our study demonstrated that pomegranate juice in a fruit beer style provides good physicochemical and nutraceutical characteristics, offering a unique twist to the craft beer industry.
