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.Read more
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.Read more
As is known, due to global warming, we are witnessing increasingly adverse and difficult weather conditions. The rise in average temperatures is in fact causing an increase in the frequency of hot and dry vintages alternating with rainy and cool years. In difficult 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. What are yeast assimilable nitrogen and gluconic acid? How can these analyses affect alcoholic fermentation? For further information on these important themes you can download the article: VINIFICATION IN THE ERA OF GLOBAL WARMINGRead more

A wine’s distinguishing features arise from the must it is made from. The latter’s analytical monitoring during the pre-fermentation phase is an essential requisite to obtain a high quality wine. Total acidity, pH, sugar content, volatile acidity are just some of the tests that allow an accurate analytical monitoring of wine must, both before and during the alcoholic fermentation phase. These analyses might not be sufficient to achieve a quality wine if the grapes have been harvested in specific weather conditions, namely hot and dry, or cool and rainy. In such years it is of paramount importance to quickly and easily assay further parameters such as gluconic acid, yeast assimilable nitrogen and malic acid. Let us see when.Read more
One of the most important processes impacting biological and organoleptic stability in wine is the so-called malolactic or secondary fermentation. Through this process, the wine sheds acidity, grows smoother and acquires more complex, mature flavours. Here you will find some key points to fully understand and control malolactic fermentation.Read more
