Have you ever wondered what gives soda or carbonated water the extra kick? Did you know that it’s not the bubble popping sensation that makes a fizzy beverage delicious but the sour-sensing taste buds on your tongue?

The human tongue is supposed to sense just five flavors: bitter, sweet, salty, sour and umami or savory. And according to a paper published in Science, the taste buds that sense sourness have an enzyme that interacts with the carbon dioxide in soda and gives the beverage its unique sensation.

So the next time you are enjoying a carbonated beverage with a friend, you can share this fun fact with them.
