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).
Even though a wine will probably taste different if itâs been open for a couple daysâincluding possibly the alcohol sticking out a bit moreâthat doesnât mean the percent of alcohol by volume will change. Same thing with changing a wineâs temperature or even aging a wineâalcohol percentages donât change. Perception is one thing, but the chemistry of wine is another. A wineâs alcohol content is determined during fermentation, when the sugar in the grapes is converted to alcohol.
