Guaranteed quality !

 

Can I measure the pH instead of the acidity of my must?
No! In winemaking, the acidity is the representation of the number of grams of acid in your wine/juice, usually expressed in grams tartaric acid per litre. This can only be measured by means of a special indicating solution like VINOFERM blue indicator.

What is pH?
pH is the measurement of the concentration of free hydrogen ions in a liquid. The pH of pure water is 7. Liquids having a larger concentration of hydrogen ions than water are acid and have a pH-value of less than 7. Liquids with a lower concentration of hydrogen ions, on the other hand, are base and have a pH value higher than 7. The pH scale runs from 1 to 14.

You can use a pH-meter in combination with the blue indicator:
Instead of adding blue indicator until the colour turns blue, add blue indicator until a pH of 7.00 is obtained. This method is more accurate and gives better readings for, amongst other things, red juices! The combination pH-meter, blue indicator and an automatic burette is a professional set-up to accurately measure acidity.
