The burning isn't caused exclusively by alcohol; thymol also causes a burning sensation, and thymol is the active ingredient in Listerine.
I ran out of Listerine, so I'm using a Crest mouth rinse without alcohol, and it still causes a burning sensation. It's not as strong as Listerine, but it's still a burning sensation. Oddly enough, the Crest rinse doesn't have thymol in it either, so that's not what's causing the burning feeling. Since I know it's not alcohol, and I know it's not thymol, it must be something else causing that sensation. At least in Crest. In Listerine, it's both.
