Micro-oxygenation and maceration are two very important phases of winemaking that influence the stability and quality of the wine. Both processes are related to the content and characteristics of the polyphenols present in wine. Monitoring the evolution of these compounds over time is a fundamental tool in the hands of the winemaker to better manage winemaking processes and guarantee the quality of the finished product.
Download the article “Managing at best maceration and micro-oxygenation in the winemaking process” to find out which are the most effective methods to monitor the parameters that influence these processes and carry out the necessary operations to obtain both a stable and quality product.
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.
The 2018/2019 oil campaign can now be considered concluded for this year and, as in other years, we are able to comment on the results of the analyses carried out on a few dozen samples from various areas of Tuscany. Furthermore we have carried out a small study to learn more about determination of the appropriate harvesting period in the case of a heterogeneous olive grove that has several cultivars.
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.

Case study: It has been thought that late-hopping and dry-hopping do not contribute to IBUs in beer. In Hackney Brewery, contrary to popular belief they have demonstrated a considerable increase in IBU value from both late and dry-hopping.
Can you perform the chemical analyses of beer in-house to monitor all the parameters useful for the production process in a simple and fast way? Discover how to save money and time improving, at the same time, the quality of your beer.
The beginning of the season was rightly perturbed by forecasts of reduced production which came true. In particular, in a few central Italian region, productivity was very low, whereas at a national level, production was below average, despite being slightly up compared to the previous oil production season. What about quality?
A low productivity and high quality of the oil have been foreseen at the launch of the 2017 oil season. In the chemical laboratories of CDR we started to analyze the oil samples of the 2017 season. We see the first results of the analysis of the oil. Are the forecasts respected?
