Colour measurement (beer)

The colour of beer is an important quality attribute. According to EBC standards, the colour of beer, wort and liquid malt substitutes is determined by measuring the absorption at a wavelength of 430 nm with a path length of 1 cm, with EBC (colour) being the measuring unit used. To eliminate possible sources of error resulting from turbidity in process measurement, turbidity compensation is used with a second wavelength of 700 nm.
