Web2 days ago · pH is the quantitative measure to gauge the acidity or basicity of a solution. The value on the pH scale ranges from 1 to 14, amongst which 7 is the value for the neutral solution. The solutions having a pH value below 7 are acidic while those having a pH value above 7 are alkaline. WebIf you measured the SO2 immediately after fermentation, you would find little to no free SO2 and a total SO2 less than half of your pre-fermentation addition. A standard addition at first racking of 80 ppm is usually required. Wines with a high pH (above 3.5) or late-harvest wines might call for 10-20 ppm more SO2.
