There are two main methods to measure the acidity of wine: 1. Litmustest (litmus test).
Drop the wine on a piece of paper, and the PH of the color on the paper will reflect the acidity level of the wine.
The PH ranges from 0 to 14, with 7 being the median, representing neutral.
The lower the PH number, the more acidic the wine is;
The higher the PH, the more alkaline it is.
2. Total acidityValue This method quantifies acidity to the degree of g/L.
Winemakers can use scientific instruments such as acidity titrators to calculate the acidity of their wines.
