Dissolved CO2 forms carbonic acid which like most acids has a sour taste. It's not as strong as something like citric or lactic acid but it's certainly present.

Dissolved CO2 forms carbonic acid which like most acids has a sour taste. It's not as strong as something like citric or lactic acid but it's certainly present. I personally don't really think of it while drinking carbonated beer but I definitely notice it while drinking sparkling water without other flavors to distract me.
- couchand 3y agoThe reaction you describe exists but this is not generally referred to as sour in the context of beer tasting. Carbonic and citric acid are usually described as "tart" or "acidic" flavors, with "sour" generally being reserved for lactic or acetic acid.
- GoldenRacer 3y agoThe guy that initially commented on it being sour was talking about Czech beers and using Euros so I assumed they were European and English might not be their first language. Their language may not have the distinction you described. I believe German uses the same word for sour and acidic for example.
- couchand 3y agoIt's the difference between bissig, like a Berlinerweiss, and sauer, like a Lambic.
