not always! if you say that ,how about a sweet green kiwi compared to a sour yellow lemon?it depends on the fruit.
because there is an ingredient that makes a acidy solution to make a sour taste in the mixture
Ascorbic acid (aka vitamin C) gives many fruits that crisp, slightly sour taste. Add citric acid of the citrus fruits and you get sour like a lemon. Malic acid in apples provides the sour/tart flavor. Tartari acid in grapes provides the tart taste there.
There are naturally occurring sugars and ascorbic acids in fruits that cause this.
