Application of Near Infrared Spectrometry for Determination of Original Wort Gravity.Peer-reviewed article

P. ČEJKA, V. KELLNER, J. ČULÍK, L. TENKL

Near infrared spectrometry makes possible determination of several analytical values in wort, respectively in beer. The advantage of the method is a speed of determination, a small necessary volume of sample, undestructivity of determination, multipurpose of apparatus. Disadvantage of the method is a higher purchase cost. In the work is made comparison of this method with results of analysators SCABA and DSA 48 on 86 samples of beer. The applied method provides better results than DSA 48, but worse than SCABA. But differences are not high and therofore it is possible to use the method in skilled practice.
