Why do acids taste sour?
Quick Answer
Acids sour-taste because hydrogen ions activate sour-sensing pathways in the tongue. Low pH changes how taste receptors respond.
The Full Story
Acidic foods such as lemons, vinegar, and yogurt taste sour because acids release hydrogen ions in the mouth. Those ions interact with sour taste receptors and ion channels in specialized taste cells. The tongue’s response is a built-in signal that something is acidic, which in nature can indicate ripeness, fermentation, or spoilage. Strong acids are dangerous and should never be tasted, but weak acids in food are a normal part of flavor.
