In addition, great importance is also attached to the quality and authenticity itself, and more frequently, during production, different aromas of fruits and plants are added, which contribute to the uniqueness and distinctiveness of the final product. In this thesis, the craft beer "Brucošica" was designed and produced using the "Grainfather" system, and its physico – chemical analysis was carried out. The obtained beer is characterized by very good organoleptic properties, while its analysis showed slight deviations from the expected values of the examined parameters (primarily IBU and EBC values), the reason for which is oxidation processes
