Original Abstract

The present work conducted a comparative chemical analysis of traditional Czech beers with degrees Plato (degrees P) ranging from 10 degrees to 12 degrees. As some breweries in the Czech Republic may use the protected geographical indication mark (PGI) "Czech Beer" (provided that the production conditions are met), differences in the chemical composition of beers, with and without the PGI, may arise. Significant differences were observed in the chemical composition of Czech beers with different degrees P values. Generally, beers with 12 degrees P exhibited significantly higher concentrations in all examined parameters, including total protein content, total carbohydrate content, total phenolic content, concentration of individual phenolic compounds, ABTS and DPPH radical scavenging capacity, organic acid concentration, and concentrations of selected elements compared to beers with 10 degrees P. The results also indicated that beers, with and without the PGI, particularly the 12 degrees P beers, did not differ in terms of chemical composition. This suggests that the production of these beers in the Czech Republic adheres to traditional brewing practices, using quality malt and typical Czech hop varieties.
