CDR BeerLab® - simple, fast and reliable analysis system of beer.

Determination of polyphenols in beer

The presence of polyphenols in beer can cause off flavours and unwanted turbidity. This phenomenon can be reduced by treatment with PVPP (Polyvinylpolypyrrolidone) during boiling or maturation, before filtration.

With CDR BeerLab® it is possible to determine the total polyphenols in a simple and fast way directly in the brewery, following its evolution throughout the brewing process.

In this way, CDR BeerLab® allows optimal processing of polyphenol removal treatment with PVPP.


Test Principle

The test is based on the use of a chromogen that reacts with the polyphenols leading to the formation of a compound that absorbs at the wavelength of 280 nm.

Calibration curve

The CDR BeerLab® method has a good correlation with the official EBC 9.11 method.
