Chemical Analysis of Beer

When does the fermentation process end? How much sugar do you need to add in the priming phase? Researchers at the CDR chemical lab “Francesco Bonicolini” conducted a study on brewing with the aim of:
• understanding which is the best method to determine the end of the fermentation process;
• determining the residual sugar concentration in order to avoid problems in the priming phase.
For this purpose we studied the evolution of fermentable sugars as well as the variation of wort density during fermentation.

Department of Agricultural, Food, Environmentaland Animal Sciences of the University of Udine Italy, under the guidance of Dr. Stefano Buiatti, performed:

  • the evaluation of correlation between the results obtained using CDR BeerLab®  and those obtaibed with EBC (European Brewery Convention)  official methods
  • the evaluation of the correlation between the results obtained with the CDR BeerLab® and those obtained with the official methods of analysis on the parameters relating to the quality control of water used in brewing

The methods of CDR BeerLab® for analysis of beer, wort and water provided statistically correlated results (p <0.05) with low standard deviation values indicating good accuracy.

The reuse of yeasts requires particular attention to recovered cell efficiency, in order to ascertain just how much sediment is required to achieve suitable fermentation for the type of beer you are looking to produce.
Determining viability, the number of live cells in yeast sediment available for reuse, is a solution to this problem, but it will be not enough.
It is important to assess recovered yeast in terms of VITALITY.
Vitality analysis indicates yeast cell health, enabling us to ascertain to what extent cells are capable of feeding and reproducing so that alcoholic fermentation can take place.
provides results in acidification power.
Therefore the CDR BeerLab® method for determining is simple to use, provides rapid results, is reliable and usable by any operator directly at the brewery on the production line.

The international reference laboratory Campden BRI, innovation, research and technology centre for the food and drinks industry, carried out a study to evaluate the performance of the CDR BeerLab® for the analysis of yeast vitality and beer VDKs concentration. In summary, the CDR BeerLab® yeast vitality and VDK analyses show a linear correlation with the results obtained by the reference methods and the values obtained were similar (correlation R2 ≥ 0.9).

Case study: is it possible to reduce the mashing time improving the process efficiency with in-house brewing process control? The case study shows that it is possible to reduce the mashing time improving the process efficiency using CDR BeerLab® to perform chemical analysis of beer for in-house brewering process control.

With the CDR system, you can perform your tests in total autonomy

Neither skilled staff nor a dedicated external laboratory is needed to use our systems. CDR FoodLab® optimizes traditional testing methods, making them faster and easier, while guaranteeing accuracy standards in line with the reference methods.

Analytical kit

CDR FoodLab® Analysis Systems use disposable pre-vialed reagents specifically developed by the research laboratories of CDR. The use of pre-vialed reagents and the analytical procedures allow:

  • a sample preparation that is quick and easy, when needed at all;
  • making analytical procedures extremely fast and easy;
  • removing all needs for complex calibration procedures.

Reagents come in aluminum packages containing 10 test tubes each to perform 10 tests (or packages for 100 tests containing 10 single packages of 10 test tubes each).

Just a few steps and results are yielded right away

Just a few steps will suffice to carry out your analysis in a rapid way in total autonomy. The system is composed of both the analyzer based on photometric technology and a kit of low toxicity, pre-vialed reagents, developed by CDR.

CDR FoodLab® is cost-effective because it does not require the use of expensive equipment and does not entail maintenance, assistance or calibration costs.
