The acidity of a beverage is quantified using a pH scale, which ranges from 0 to 14. A pH value below 7 indicates acidity, 7 is neutral, and above 7 is alkaline or basic. Mountain Dew, a popular citrus-flavored soft drink, registers on the acidic side of this scale. Typical measurements place its pH around 3.2 to 3.7. This acidity stems from ingredients like citric acid, which contribute to its tart flavor profile.
The acidity level of beverages is relevant for several reasons. From a food science perspective, pH affects the taste and preservation of a product. In terms of health, highly acidic drinks can contribute to dental erosion by weakening tooth enamel over time. Historical trends show a general increase in the consumption of acidic beverages, making awareness of their pH increasingly important for informed consumer choices.
