Biogenic amines are low-molecular organic bases, formed by the decarboxylation of neutral and basic amino acids. The accumulation of amines in the human body, leading to a series of adverse reactions such as vomiting, diarrhea or headaches is caused by the adoption of excessive doses or impairment of natural enzymes. The aim of the work was to determine the level of biogenic amines in samples of sour beer available on the market, worts of varying degrees of bitterness (0, 4 and 8 IBU) and in beers produced from these worts. Based on the results, it was claimed that the concentration of biogenic amines in acidic beers exceeds even 10 times the concentration found in lager beers. However, no significant effect of bitterness on the final content of biogenic amines with the exception of histamine and cadaverine was observed.
