This method describes the determination of color of (Congress) wort using color discs.
Malt intended for use in beer brewing or elsewhere in the food industry
The determination of the color of the Congress wort is carried out under defined lighting conditions through a visual comparison of the wort color with the appropriate color discs. Please note that several individuals should perform the color measurement if possible.
The method describes how to determine the β-glucans in wort or Congress wort by means of a colorimetric method.
Applicable for all (laboratory) worts
The colorimetric method may be used for the determination of high molecular weight β-glucan in wort; it is based on the photometric evaluation of a β-glucan color complex. The soluble β-glucan from barley reacts with a buffered solution, forming a color complex within 30 minutes. The absorbance of the β-glucan color complex is measured at 550 nm.
This method describes the spectrophotometric determination of the color of roasted malt beer/extract.
Roasted malt beer/extract intended for use in beer brewing or elsewhere in the food industry.
This method describes the visual determination of the color of roasted malt beer/extract.
Roasted malt beer/extract intended for use in beer brewing or elsewhere in the food industry.
The method describes the determination of the color of wort and beer by means of color discs.
Suitable for all beer worts and beers.
The colour is determined under defined lighting conditions by an optical colour comparison, whereby two halves of vision must be adjusted to the same colour intensity [1, 2].
Barley intended for the production of malt is to be evaluated on the basis of the characteristics described below.
