PRINCIPLE

A fixed quantity of copper sulfate mixed with alkaline salts in tablet form is added to a known quantity of diluted wine. The mixture creates a temperature increase that causes the typical reaction of reducing sugars. The results are obtained by observing the color resulting from the excess of blue copper salts and/or red copper oxide formed. 

ADVANTAGES

- Quick determination of the stage of alcoholic fermentation
- Analysis in less than 1 minute (except for discoloration)
- Clear results thanks to a color chart
