What is pH? 

pH measures the concentration of free hydrogen ions in a liquid. The pH of pure water is 7. Liquids with a more significant concentration of hydrogen ions than water are acids with a pH value of less than 7. On the other hand, liquids with a lower concentration of hydrogen ions are base and have a pH value higher than 7. The pH scale runs from 1 to 14.

Can I measure the pH instead of the acidity of the must?

No! In winemaking, acidity represents the amount of acid in your wine/juice, usually expressed in grams of tartaric acid per litre. This can only be measured with a particular indicating solution like Vinoferm® Blue Indicator. However, you can use a pH meter combined with the blue indicator: instead of adding the 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 automatic burette is a professional set-up for accurately measuring acidity.
