Sour is a taste sensation that is often described as sharp, tangy, or acidic. It is one of the five basic tastes and is commonly experienced when consuming foods that contain acids, such as citrus fruits, vinegar, and fermented products. The perception of sourness is primarily due to hydrogen ion concentration and pH level in the food or drink.
