Generally, the lower the pH, the higher the acidity in the wine. However, there is no direct connection between total acidity and pH (it is possible to find wines with a high pH for wine and high acidity).
Having the correct level of acidity will also significantly aid the fermentation process and help to inhibit the growth of unwanted micro-organisms during and after the fermentation. Having the proper acidity level in the finished wine will also help to keep the negative effects of oxidation to a minimum.Finished wines that are too low in acid can eventually take on a slight raisin or caramel flavor, and in more extreme cases the wine can turn slightly brown or orange in color as well.cidity is a major component to producing a stable wine with an agreeable balance and overall character. Without controlling acidity the result can be a wine that either tastes too sharp at one extreme, or flat and lifeless at the other.
