By Shumaila Saeed || Updated on December 25, 2023
Tart is a sharp and acidic taste often pleasantly invigorating, while sour is a basic taste sensation often associated with acidity and can be less pleasant or harsh.
Key Differences
Tartness is characterized by a sharp and often pleasantly stimulating taste, commonly associated with certain fruits like lemons and berries. Sourness, on the other hand, refers to an acidic taste that can range from lightly tangy to harshly acidic, often associated with spoiled or fermented foods.

Tart flavors are typically perceived as zesty and refreshing, often found in fruits like apples and grapes, and are sometimes sweetened to balance the taste. Sour tastes are more closely associated with a high level of acidity, as found in unsweetened yogurt, vinegar, or spoiled milk.
