In opposition to what we think, the stinging sensation of bubbly wines such as Champagne or Prosecco is not due to bubbles exploding on our tongue. Some researches have found out that a chemical reaction actually happens between Carbone Dioxyde (CO2, bubbles that we see in the glass) and saliva. The combination of both creates some Carbonic Acid (H2CO3) which exites our nerves, especially the Trigeminal Nerve. This latter is connected to our mouth, our eyes and our nose. This is what provocates this stinging feeling. Just like when we eat mustard or an onion…
