Beer is a low-alcohol drink with a characteristic aroma and a pleasant bitter taste. The main raw materials for beer production are malt, brewer's yeast, hops and water. The total phenolic content as well as the total flavonoid content in selected beer samples shows significant differences depending on the type of beer and ranges from 263.3 mg gallic acid/L in light to 590.7 mg gallic acid/L in dark beers, respectively and 53.9 mg catechin/L for light beers up to 214.8 mg catechin/L for dark beers. The presence of phenolic components is also important because of the sensory characteristics they can give to beer.
