CDR WineLab® for the correct management of alcoholic fermentation
In extreme climatic conditions, in addition to the usual analysis of sugar, total acidity, pH and acetic acid, yeast assimilable nitrogen and gluconic acid are the fundamental parameters available to the oenologist to better manage the fermentative process, an essential starting point to obtain a quality wine.

Malolactic fermentation: chemical and biological aspects
Why is malolactic fermentation so important? How can the biological and organoleptic stability be enhanced? Which bacteria are responsible for malolactic fermentation? What conditions favour malolactic fermentation?
Follow up on the chemical and biological aspects of malolactic fermentation.

Managing at best maceration and micro-oxygenation in the winemaking process
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.
CDR WineLab® validation by an important reference laboratory
The CDR WineLab® wine analysis system has been validated by the ISVEA reference laboratory.
Comparative assays between the method exploited by the CDR WineLab® analyzer and the reference methods were carried out using sequences of samples made up of different types of wine in order to verify the reliability of the results obtained with the CDR WineLab® system.
Reference methods used for the validation:
- Glucose and fructose – HPLC method
- Malic acid – HPLC method
- Volatile Free Fatty Acid (FFA) – Titration after distillation method EEC regulation 2676/1990 17/09/1990 ECC OJ L272 03/10/1990, Exhibit point 14, OIV MA-F-AS313-02-ACIVOL 2006
- Total sulphur dioxide – Titration after distillation method EEC regulation 2676/1990 17/09/1990 EEC OJ L272 03/10/1990, Exhibit point 25 par 2.2
The reference institute concluded that the tested CDR WineLab® methods are to be considered substantially valid. In fact, the reference methods are statistically equivalent (95%) to CDR WineLab® methods.
