Vinegar reduces bitterness?

[Isabelle49]

Bitter is bad, for my taste anyway. Am reading that vinegar can counteract bitterness. Is this for realz? Thanks.

What are you vaping that's bitter? I've tried e-liquid I didn't like- coffees, but none have ever been bitter...

I've read that adding a tiny amount of apple cider vinegar can round off sharp tastes. I can't vouch for that advice, though it's not specific to bitterness. But as a thought experiment, it holds up a bit. Alkali usually imparts a bitter taste, and vinegar might provide a balancing acid.
