sour taste

Lemon's sharp bite

Sour taste is one of the five basic tastes, triggered by acidic substances like citrus, vinegar, or fermented foods.

The sensation comes from hydrogen ions stimulating receptors on the tongue.

Sourness can signal spoilage—milk that has gone sour—or be deliberately sought in foods like pickles, yogurt, and sourdough bread.
