The invention discloses a method for rapidly determining a Kol-bach value of beer malt. The method comprises the following steps: under set modeling conditions, acquiring near infrared spectrum map information of a representative malt sample, and measuring the content of soluble nitrogen and the content of total nitrogen of the sample by using a traditional standard physicochemical method; selecting a proper chemometric resolution method, respectively establishing mathematical relationships between the spectrum map information and the soluble nitrogen of the sample as well as the spectrum map information and the total nitrogen of the sample, namely quantitative models; completing performances of the models by validating the sample, and analyzing the soluble nitrogen and the total nitrogen of an unknown sample by utilizing the models, so as to obtain the Kol-bach value according to a Kol-bach value formula. The method is operated easily, accurately and rapidly, and is relatively high in practicability; a single sample can be measured within 30 seconds; urgent requirements of beer brewing enterprises and malt production enterprises can be met.
