Foods with low to moderate acidity taste tart. Foods with high acidity levels taste sour. For example, lactic acid in yogurt creates a tart flavor, while citric acid in lemons creates a sour flavor.
This difference in pH level affects how strong the taste feels. Higher acidity leads to a stronger, sharper reaction on your tongue.
