Description
Vinoferm blue reagent is essential for measuring the acidity of wine or must, expressed in grams of tartaric acid per liter. Although the pH meter measures the concentration of hydrogen ions, it can be used in combination with the blue reagent for accurate acidity measurement.

Why can't a pH meter be used to measure must acidity ?
Measuring acidity in winemaking concerns the production of a certain quantity of acid in your wine or must, expressed in grams of tartaric acid per liter. This can only be measured with the blue reagent.
What is pH ?
pH measures the concentration of free hydrogen ions in a solution. For example, the pH of pure water is 7. Liquids with a higher concentration of hydrogen ions than pure water are acidic and have a pH below 7, while those with a lower concentration are basic (alkaline) and have a pH above 7. The pH scale ranges from 1 to 14.
Combined use of pH meter and blue reagent :
Instead of adding the reagent until the blue color appears, you add the blue reagent until you reach a pH of 7.00. This method is more accurate and easier to interpret, especially for red juices! The combination of pH meter, blue reagent and automatic burette is a professional technique for measuring acidity with great precision.
