Wine Trivia #1
B. Its naturally high acidity ensures that it maintains its freshness
The acids in wine are an important component in both winemaking and the finished product of wine. They are present in both grapes and wine, having direct influences on the color, balance and taste of the wine as well as the growth and vitality of yeast during fermentation and protecting the wine from bacteria. The measure of the amount of acidity in wine is known as the “titratable acidity” or “total acidity”, which refers to the test that yields the total of all acids present, while strength of acidity is measured according to pH, with most wines having a pH between 2.9 and 3.9. Generally, the lower the pH, the higher the acidity in the wine.
The acidity of a wine is one of its most appealing characteristics, enhancing its refreshing, crisp qualities as well as enabling wines to be paired with foods so successfully. Acidity complements foods in a palate-cleansing, refreshing manner. The acidity is usually tasted as soon as it comes into contact with the sides of your tongue, similar to biting into a cold Granny Smith apple. Cooler growing climates produce wines higher in tartaric and malic acid, so a Chardonnay from Burgundy will have a higher acidity level than California Chardonnay.
