Do carrots become sweeter when old?

Yes, carrots can become sweeter as they age, particularly if they are left in the ground longer. This is due to the conversion of starches into sugars, which can occur in cooler temperatures or after exposure to frost. However, as carrots continue to age beyond a certain point, they may start to lose flavor and texture, becoming woody or bitter instead. Therefore, while some aging can enhance sweetness, there is a limit to how long they should be stored.
