FIELD: beer.

SUBSTANCE: invention relates to brewery. Described is non-alcoholic fermented beer with an alcohol content of less than 1.0% ABV, containing methional, 2-methylbutanal, 3-methylbutanal, 2-methylpropanal, phenylacetaldehyde, and furfuryl alcohol and maltotriose in certain concentrations. The method for producing the beer therein includes the stages of: fermentation of wort with live yeast to produce fermented wort; subjecting the fermented wort to one or more additional stages of the method, producing non-alcoholic beer; and pouring the non-alcoholic beer in sealed containers; where either the fermentation results in the production of non-alcoholic fermented wort or the fermentation results in the production of alcoholic fermented wort and the alcohol is then removed, producing non-alcoholic fermented wort or non-alcoholic beer; and where the heated wort, non-alcoholic fermented wort, and/or non-alcoholic beer is brought into contact with a hydrophobic molecular sieve based on a silicate containing SiO₂ and Al₂O₃ in a molar ratio of at least 15.

EFFECT: possibility of effectively removing flavouring substances promoting the occurrence of undesirable flavouring notes in non-alcoholic beer.
